How Long Does It Take to Build an App? Timeline Data From Our 44 Builds
First-party app development timeline data from the 44 builds in our published case studies. Every first version shipped in 5 to 10 weeks, with a median and a mean of 7 weeks. This paper breaks the timelines down by industry, product type and platform, counts which builds reported time saved, revenue, conversion or volume results, and sets the numbers next to Clutch's published project timelines (9 to 13 months) with an honest account of why a first release and a full engagement are different measurements.
Part of the guide: Software development
Key takeaways
- Across the 44 builds in our published case studies, the first launched version took 5 to 10 weeks. The median was 7 weeks and the mean 7.05 weeks.
- 27 of the 44 builds (61%) took 6 or 7 weeks, and 40 of 44 (91%) shipped in 8 weeks or less. Only 4 took 9 weeks or more.
- Booking and dispatch products ran longest (median 8 weeks across 9 builds), because they connect to live inventory, payments or other parties. Social and community apps ran shortest (median 6 weeks across 7 builds).
- Mobile-only apps had a median of 6 weeks (7 builds); apps with both a web and a mobile side had a median of 8 weeks (5 builds); web apps a median of 7 weeks (28 builds).
- 42 of 44 builds report a volume result (users, listings, transactions), 30 report time saved on a task, 20 report a conversion or retention rate, and 16 report a money result (11 revenue or value, 5 cost).
- Clutch's pricing pages (updated Sep 21, 2026) give about 13 months for a typical custom software project, about 11 months for mobile apps and 9 months for web development. Those figures and ours measure different things: a whole client engagement versus a first release.
How long does it take to build an app?
A focused first version of an app takes about 5 to 10 weeks to build once the scope is agreed. That is not an estimate: it is the full range across the 44 builds in our published case studies, where the median and the mean were both 7 weeks. A full product with many roles, integrations and later phases takes longer, which is why published market figures run to months.

Most pages that rank for this question give ranges from agencies’ experience, such as “2 to 4 months for a simple app”. This paper does something different: it publishes one team’s actual build times, product by product, with the client names and links, so you can find the build that looks most like yours.
Key findings
- The middle is narrow. 27 of 44 builds (61%) took 6 or 7 weeks. The standard deviation is 1.1 weeks.
- Only 4 builds took 9 weeks or more: Spirit Airlines (10), Homer (9), the Miami Dolphins (9) and Life Line Ambulances’ event dispatch platform (9). All four connect several parties or live inventory.
- Product type matters more than industry. Booking or dispatch products had a median of 8 weeks; social and community apps a median of 6. Industry medians sit between 6 and 8.
- Mobile alone was not slower. Mobile-only apps had a median of 6 weeks. Adding a web side as well (web and mobile) moved the median to 8.
- Results are mostly measured as volume and time. 42 builds report a volume result, 30 report time saved, 20 a conversion or retention rate and 16 a money result.
- Fast did not mean small. Builds that reported a revenue or cost result averaged 6.81 weeks, a little under the overall mean.
- Market figures measure something else. Clutch’s pages give 9 to 13 months for typical projects. That is a whole engagement as reviewed by clients; ours is the first launched version.
Method: what this data is and what it is not
The dataset is the 44 software builds published as case studies on this site, all delivered by our in-house engineering team. For each build we took the reported timeframe (in whole weeks), the industry, product type and platform labels from our case study records, and every impact statistic the case study reports. We counted them with a short script on October 31, 2026. Nothing was sampled, adjusted or removed.
What the data is:
- Our own builds. These are first-party numbers from one engineering team, not a market survey.
- First releases only. Each timeframe is the time to the first launched version, not the life of the product. Work after launch (new features, phase two, maintenance) is not counted.
- The timeframe as reported. Most case studies describe it as kickoff to a finished build; one (GoHangars) as first call to a shipped MVP. Scoping before kickoff is not consistently included. Timeframes are whole weeks, so a “7 weeks” build could be 6.5 or 7.4.
- No survey. We did not ask clients to estimate anything. The impact numbers are the ones each case study reports.
What it is not:
- Not every project we have done. It covers the builds we have published as case studies, which are, by definition, ones that launched. Projects that changed direction, paused or are under NDA are not in it. That is a selection effect and it probably makes the published set look tidier than a full project log would.
- Not a price study. Our builds typically cost $7,000 to around $25,000 to $30,000, but this page studies time, not price.
- Two of the 44 are websites, not apps (Internet Travel Solutions and JetStarix, 5 weeks each). We keep them in the headline numbers because they are in the portfolio; without them, the 42 app builds still have a median of 7 weeks and a mean of 7.14.
How we coded the groups:
- Industry: the industry label on each case study, grouped into 11 families (for example, “Healthcare (EMS)” and “Health and Fitness” both count as healthcare and wellness).
- Product type: a build can carry more than one type. Marketplace = marketplace in the type or the marketplace service; booking or dispatch = booking or dispatch in the product type, or a booking-platform tag; AI = AI app development is a core service; internal tool = internal tools or custom CRM service; ecommerce = an ecommerce industry label or a store; social or community = consumer social, community, dating, networking or social fitness; portal = customer portal service on an app build.
- Results: we coded each of the 211 impact statistics (the build-time line excluded) by hand into time saved, money, conversion or retention, volume, or other. Definitions are in the results section below.
How are build times distributed?
Build times cluster tightly around 6 to 8 weeks. 38 of the 44 builds (86%) fall in that three-week band, and the tails are thin on both sides.
| Weeks | Builds | Share | Cumulative |
|---|---|---|---|
| 5 | 2 | 4.5% | 4.5% |
| 6 | 14 | 31.8% | 36.4% |
| 7 | 13 | 29.5% | 65.9% |
| 8 | 11 | 25.0% | 90.9% |
| 9 | 3 | 6.8% | 97.7% |
| 10 | 1 | 2.3% | 100% |

Does the industry change how long an app takes?
Only a little. Every industry group in the data sits inside the same 5 to 10 week band, and the medians run from 6 to 8 weeks. Where an industry looks slower, it is usually because its builds in this set happen to be booking platforms or multi-party transaction tools.
| Industry group | Builds | Median weeks | Mean weeks | Range | Builds in the group |
|---|---|---|---|---|---|
| Travel and aviation | 7 | 7 | 7.0 | 5 to 10 | Alendil, Birdie, GoHangars, Internet Travel Solutions, JetStarix, Spirit Airlines, Wingman Pilot |
| Healthcare and wellness | 6 | 7.5 | 7.3 | 6 to 9 | Infuse CTL, Life Line Ambulances (3 builds), StackStack, Stridely |
| Food, hospitality and local | 5 | 6 | 6.6 | 6 to 8 | Adapted Co, Coo Local Deals, Farmers Market Haul, Fer Vor, Push App |
| Social, community and publishing | 4 | 6.5 | 6.5 | 6 to 7 | Common Faktor, GreekVibes, Our Fusion, Papri |
| Marketing and creators | 4 | 7 | 6.8 | 6 to 7 | Campaign Sync, DEMP Agency, Eva Social, Social Grid |
| Sports and entertainment | 4 | 7 | 7.3 | 6 to 9 | Bingo Buddy, Load Management, Miami Dolphins, Miami Open |
| Education and nonprofit | 3 | 6 | 6.7 | 6 to 8 | Coo Fundraiser, HirePrep, My Rich Aunt |
| B2B software and finance | 3 | 7 | 7.0 | 6 to 8 | Edge Case Capital, Think K-12, Probado |
| Ecommerce and retail | 3 | 8 | 7.3 | 6 to 8 | Cyrano Brands, Drop My Drip, Loop Biolabs |
| Real estate | 3 | 8 | 8.0 | 7 to 9 | DAIN, Homer, Vassumable |
| Home services | 2 | 7.5 | 7.5 | 7 to 8 | Hago, Simply Bids |
Source: industry labels and timeframes on our 44 published case studies, grouped by us, counted Oct 31, 2026. Groups of 2 or 3 builds are too small to generalise from.
Real estate has the highest mean (8.0 weeks), and two of its three builds are transaction platforms where agents, lenders, inspectors, servicers and buyers all need their own view. The quickest groups, food and local and social apps, are mostly single-sided consumer products.
Which kinds of app take longest to build?
Booking, dispatch and portal products take longest; social apps and marketplaces take least. The difference is about one to two weeks at the median, and it tracks how many outside systems and user roles the first version has to handle.
| Product type | Builds | Median weeks | Mean weeks | Range | Examples |
|---|---|---|---|---|---|
| Marketplace | 16 | 7 | 6.8 | 6 to 8 | Hago, GoHangars, Wingman Pilot, Simply Bids, Infuse CTL |
| Booking or dispatch | 9 | 8 | 7.8 | 6 to 10 | Spirit Airlines, Miami Dolphins, Miami Open, Bingo Buddy, Respond Central |
| Social or community | 7 | 6 | 6.6 | 6 to 8 | Stridely, Common Faktor, Our Fusion, Push App, Papri |
| AI feature at core | 6 | 7.5 | 7.5 | 7 to 8 | DAIN, Birdie, HirePrep, Eva Social, Think K-12 |
| Portal | 5 | 8 | 8.0 | 6 to 9 | Homer, Miami Dolphins, Miami Open, Loop Biolabs |
| Internal tool | 4 | 7 | 7.3 | 6 to 9 | Edge Case Capital, DEMP Agency, Life Line event manager |
| Other SaaS or workflow app | 4 | 6.5 | 6.8 | 6 to 8 | Campaign Sync, Coo Fundraiser, StackStack, Vassumable |
| Ecommerce | 3 | 8 | 7.3 | 6 to 8 | Cyrano Brands, Drop My Drip, Loop Biolabs |
| Website (not an app) | 2 | 5 | 5.0 | 5 | Internet Travel Solutions, JetStarix |
Source: our 44 published case studies, product types coded by us as described in the method, Oct 31, 2026.
Two things stand out. Marketplaces are the most common build in the set (16 of 44) and still came in at a 6.8-week mean: two-sided does not have to mean slow when the first version keeps to one transaction type. And every AI build took 7 or 8 weeks, never 6, which fits the extra testing that model output needs on real inputs before launch.
Web, mobile or both: does platform matter?
Platform matters less than you might expect. Mobile-only apps were the quickest app group in our data, and the slower group was builds with both a web and a mobile side, which is two front ends on one back end.
| Platform | Builds | Median weeks | Mean weeks | Range |
|---|---|---|---|---|
| Web app | 28 | 7 | 7.3 | 6 to 10 |
| Internal tool (web) | 2 | 6 | 6.0 | 6 |
| Mobile app | 7 | 6 | 6.6 | 6 to 8 |
| Web and mobile | 5 | 8 | 7.6 | 6 to 9 |
| Website | 2 | 5 | 5.0 | 5 |
| All web-based apps (web app + internal tool) | 30 | 7 | 7.2 | 6 to 10 |
| Any mobile (mobile + web and mobile) | 12 | 7 | 7.0 | 6 to 9 |
Source: platform labels and timeframes on our 44 published case studies, counted Oct 31, 2026.
The 5 web-and-mobile builds include three for Life Line Ambulances, where crews use handsets in the field and dispatchers or facilities use a web view. That two-audience shape, not the mobile part on its own, is what adds the time.
For mobile, add store review to the calendar. Apple says App Review typically reviews at least 50% of submissions in less than 24 hours and 90% in less than 48 hours (checked Oct 31, 2026). Google Play says some new apps from certain developer accounts may see review times of up to seven days or longer in exceptional cases (checked Oct 31, 2026).
What results did these builds report?
Nearly every build reports a volume result, two in three report time saved on a real task, and about one in three reports a money result. We coded every impact statistic on the 44 case studies, 211 in total once the build-time line is removed.
| Result kind | What we counted | Builds | Share of 44 | Statistics | Mean build weeks | Example |
|---|---|---|---|---|---|---|
| Volume | Users, listings, transactions, jobs, bookings, events | 42 | 95% | 72 | 6.98 | Hago: 140,000 jobs in year one |
| Time saved | A task, cycle or turnaround got faster | 30 | 68% | 41 | 7.27 | Spirit Airlines: group quote from 3 days to 40 minutes |
| Conversion or retention | Completion, rebook, repeat, retention, reply, win, cancellation or abandonment rates | 20 | 45% | 25 | 7.10 | Miami Open: 68% booking completion vs 19% on the old form |
| Money | Revenue, money raised or booked, earnings or value lift, or a cost reduction | 16 | 36% | 18 | 6.81 | My Rich Aunt: $3.1M raised by students in 18 months |
| Other | Quality, accuracy, engagement and similar | 35 | 80% | 54 | n/a | GreekVibes: 91% directory accuracy |
Source: 211 impact statistics on our 44 published case studies, coded by hand into one kind each, Oct 31, 2026.
Of the 16 money results, 11 are revenue or value (for example, $41M in project value on Simply Bids and $6.8M creator revenue on Cyrano Brands) and 5 are cost reductions (for example, Probado’s cost per test round falling from $4,800 to $390). 11 builds report both a time saving and a money result. Only 2 builds (Adapted Co and Papri) report volume alone with no time, money or conversion figure, and 2 (DAIN and Spirit Airlines) publish a single headline statistic.
A caution on reading this: these are the results each case study chose to report, not a controlled measurement. They show what kind of outcome a first version can be judged on within its first year, not what every build achieved.
How does this compare with published market timelines?
Published market figures are many times longer than ours, and the main reason is that they measure a different thing. Clutch’s pricing pages, built from verified client reviews and updated September 21, 2026, give these typical timelines:
| Source | What it covers | Typical timeline | About in weeks | Our median, for scale |
|---|---|---|---|---|
| Clutch: software development pricing | Custom software development projects | About 13 months | ~56 | 7 weeks |
| Clutch: mobile app development pricing | Mobile app development projects | About 11 months | ~48 | 6 weeks (mobile only) |
| Clutch: web development pricing | Web development projects | 9 months | ~39 | 7 weeks (web apps) |
Market data from Clutch pricing pages, each marked updated Sep 21, 2026, checked Oct 31, 2026. Weeks converted by us at 4.33 weeks a month. Our figures from our 44 published case studies.
Why the gap is real but not a fair race:
- A first release is not a whole project. Our number stops at the first launched version. Clutch’s pages do not say where a project timeline starts or ends, and a client reviewing an agency on a directory is usually describing the whole relationship, which can include discovery, later phases and ongoing work after launch.
- MVP scope versus full product. Every build here had its scope cut to what the first release needed to prove. A full product brief with every role, report and integration on day one is a bigger job, and it takes longer with any team.
- The start line differs. Most of our timeframes run from kickoff. Weeks spent deciding what to build before kickoff are, in most cases, not in the number.
- Selection. Our set is the builds we published, which all launched. A review-based market average includes projects that ran long, changed vendor or restarted.
- Team shape. One in-house engineering team built each product, so there was no hand-off between separate vendors partway through.
Clutch also reports the most common project cost range as $10,000 to $49,999 for custom software and mobile apps, which fits shorter, focused first builds better than a 13-month average does. GoodFirms publishes app cost and time surveys too, but its primary report page was not reachable when we checked on October 31, 2026, so we have not quoted it.
The practical reading: if you are planning a first version, a 6 to 8 week build window is realistic for a focused scope. If a quote says 9 to 13 months, ask whether it is for a first release or for the whole roadmap, because those are different plans.
What pushes a build from 6 weeks to 10?
In our data, the extra weeks came from live connections to other systems and from several parties sharing one workflow. The four longest builds show it:
- Spirit Airlines, 10 weeks. Group quotes check live fare-class inventory through a Sabre integration, run an approval chain from agent to supervisor to revenue management, and split deposits and balances through Stripe. Average group quote time fell from 3 days to 40 minutes. Case study.
- Miami Dolphins, 9 weeks. A live suite map with sightlines, configurable packages with live pricing, e-signature checkout and CRM-linked inventory locking across a full season. Enquiry to signed contract fell from 21 days to 6. Case study.
- Homer, 9 weeks. Agents, lenders, inspectors and buyers on one shared transaction timeline with milestone-based document requests and permissions. Time to close fell from 43 to 32 days. Case study.
- Life Line Ambulances event dispatch, 9 weeks. A live map on each event’s own site plan, few-tap incident reporting, offline operation and an organiser view. Dispatch response at large events fell from 9 minutes to 90 seconds. Case study.
And at the other end, what kept builds at 6 weeks: one main user type (StackStack, Stridely, GreekVibes), a single core transaction (My Rich Aunt, Coo Local Deals), or an internal tool for one team (Edge Case Capital, DEMP Agency). If your first version can look like one of those, plan for the short end. If it looks like the four above, plan for 8 to 10 weeks.

How to use this data to plan your own build
Find the two or three rows above that look most like your product, by type more than by industry, and use their weeks as your first planning range. Then check the three things that moved our builds to the long end: live connections to outside systems, more than two user roles sharing one workflow, and a web and a mobile front end in the first release. Each one you can move to phase two takes time out of the first version.
If you want a timeline for your own scope, book a free 30-minute call. We scope the first version with you and send a written quote with a fixed scope and a week-by-week plan; our app and web app builds typically cost $7,000 to around $25,000 to $30,000, depending on features, and we work project-based or hourly. For more on how we approach first versions, see MVP development, mobile app development, web app development and marketplace app development.
