Apps and software we build for Illinois businesses
Warehouses and staffing agencies
You clock shift workers in on fingerprint terminals and cannot produce a signed release for each of them.
We build a time and attendance app that uses badge or PIN by default, offers biometrics only after an electronic release, and deletes data on a published schedule, so your exposure drops before a claim arrives.
Internal tools developmentSimilar build: Life Line Ambulances
Freight brokers and 3PLs
Your dispatchers rebuild load status from emails every morning and shippers keep calling to ask where their freight is.
We build a dispatch board that flags late loads to a named owner and a shipper portal that answers the status question without a phone call.
Customer portal developmentSimilar build: Life Line Ambulances
Grain elevators, co-ops and equipment dealers
Scale tickets and grower contracts live on paper and never match the settlement sheet on the first try.
We build an offline-first mobile app for tickets and contracts that syncs to a settlement dashboard when the signal returns, so month end stops taking a week.
Employers hiring at volume
You want AI to help sort applicants but cannot show what it looked at or prove candidates were told.
We build a screening tool that logs every input, leaves out zip code and similar proxies, sends the AI-use notice and keeps a person on the final decision.

How to compare app development companies in Illinois
Ask every firm on your Illinois shortlist for a written price, launch times on named projects, who writes the code, and whose name the code and store accounts are in. Our answers: $7k to $30k, a first release in 5 to 10 weeks, Shivam Pujara's in-house team, and everything in your name. The full list is in how to choose a software development company.
How a build works, from first call to handover
Across our published builds the first release shipped in 5 to 10 weeks, with a median of 7. Integrations and compliance work add more time than screens do. See how long our builds took.
Free 30-minute project call, then written scope and quote, then design you approve, then build with weekly demos, then test and launch, then handover you own, then support when you need it.

“Working with [our team] was the best decision we made in this process. We went from a 6 month development cycle to a 10 week timeline.”
“They translated very complex operational processes into software that feels simple for our team to use.”
“Communication was clear, timelines were realistic, and the final product matched what was scoped.”
Why Illinois companies hire us as their mobile app developers
Illinois is the state where a fingerprint clock-in or a face login can turn into a class action. If your app needs biometrics, we build the written notice, the signed release and the retention schedule into the first release, the way the Biometric Information Privacy Act asks. If AI will help you screen applicants, we build the notice and the human sign-off that Illinois has required since January 2026. You get an app your lawyer can review in an afternoon, not a rebuild later. When you need mobile apps or AI features, compliance is part of the quote, not an extra.
Proof matters more than promises, so here is ours. For Spirit Airlines we cut group quotes from 3 days to 40 minutes. For Life Line Ambulances we cut staffing conflicts by 89% and invoicing from 24 days to 6. We work remotely with a weekly demo you can click through, a staging link your team can test, and a recorded handover when it ships. Most Illinois clients start with an internal tool or a customer portal that replaces a spreadsheet.
How to hire an app developer in Illinois: 4 things to settle first
- Will your app touch biometrics?
If yes, consent and retention must be in the first release under the Biometric Information Privacy Act. If biometrics are optional, leaving them out of version one often saves time and money.
- Is AI part of a hiring decision?
Public Act 103-0804 requires notice from January 1, 2026. Decide what the AI suggests and what a person approves.
- Can I see the scope and price in writing?
Screens, integrations, milestones and the price on paper before work starts. See our pricing for what pushes a build from $7,000 toward $30,000.
- Who will own the code and accounts?
Code, app store and hosting accounts in your name, plus a recorded video walkthrough and written documentation at handover. That is our standard.
Which Illinois laws change how your app is built?
The Illinois rules we design consent screens, data retention and breach logging around. A planning summary, not legal advice.
| Rule | What it means for the build |
|---|---|
| Consumer privacy law | No comprehensive consumer privacy law in force as of 2026-10-31. Apps serving users in other states still need to meet those states' rules, and sector laws (health, finance, children) apply regardless. |
| Data breach notification | 815 ILCS 530/10 (Personal Information Protection Act): notice deadline most expedient time possible and without unreasonable delay (AG notice if >500 Illinois residents). We build audit logs that show what data was touched, so notice can be accurate and on time. |
| Biometric Information Privacy Act, 740 ILCS 14 | Written notice, written release and public retention policy before collecting biometrics; private right of action, $1,000 negligent / $5,000 intentional liquidated damages. (effective 2008-10-03) |
| SB 2979, Public Act 103-0769 (BIPA amendment) | Repeated collection of the same person's biometric by the same method is one violation (per-person damages); electronic signature satisfies the written release. (effective 2024-08-02) |
| HB 3773, Public Act 103-0804 (Human Rights Act, AI in employment) | Employers may not use AI that discriminates (incl. zip code as proxy) in hiring, promotion, discipline etc.; must notify employees when AI is used. (effective 2026-01-01) |
| Sales tax on SaaS | partial: 86 Ill. Adm. Code 130.1935: cloud software never downloaded not taxable; downloaded canned software taxable unless license meets all five conditions. Chicago Personal Property Lease Transaction Tax can reach SaaS (rate not verified).. Relevant if you will sell your app as a subscription. |
| Time zone | Central. Our team works from San Francisco (Pacific), with remote specialists covering other hours, so Illinois working hours overlap with ours every weekday. |

How much does it cost to build an app in Illinois?
With us, a typical app or web app costs $7,000 to around $25,000 to $30,000, whether you are in Chicago, Rockford or Carbondale. A focused first version sits near the low end; payments, several user roles, integrations or biometric consent flows move it up. You get the price in writing after a free 30-minute call, quoted per project or by the hour.
How much does it cost to hire someone to build an app?
Hiring our team to build an app usually costs $7,000 to around $25,000 to $30,000 for the full project. That includes design, the iOS or Android app, the backend, testing, store launch and a recorded handover. Biometric consent flows or several user roles move it toward the top. We quote project-based or hourly, in writing, after a free 30-minute call.
Freelance app developer or app development company: which costs less?
A freelancer usually quotes less up front, but the quote may leave out design, backend, testing and support after launch. A company quote should cover all of it, and you should check who writes the code. For an Illinois app that collects biometrics, ask who builds the BIPA consent and retention flow. Ours is part of the quote, with no extra line item.
How long does custom software take to build?
From signed scope to first release, our 44 published builds took 5 to 10 weeks, with 7 the median. Spirit Airlines' group booking system took 10 weeks because it runs on live fare inventory; simpler internal tools land closer to 5. We set your date once the written scope is agreed, and you see working software at a demo every week.
Can you build a BIPA-compliant app with fingerprint or face login?
Yes. Under the Illinois Biometric Information Privacy Act, you need written notice, a written release and a public retention policy before collecting biometrics, and damages run $1,000 to $5,000 per violation. We build the consent screen, store the electronic release, and automate deletion on your retention schedule. Your counsel signs off on the wording; we make the app follow it.
Does Illinois have a privacy law my app must follow?
Illinois has no California-style consumer privacy law. The rules that usually matter are BIPA for biometrics, the 2026 Human Rights Act amendment for AI in employment decisions, and the Personal Information Protection Act, which requires breach notice without unreasonable delay and an Attorney General notice above 500 affected residents. We tell you on the free call which ones touch your app.
Do I need an app developer in Illinois, or can I hire a remote team?
A remote team works well when the process is tight. We have no Illinois office; our in-house engineers in San Francisco are two hours behind you, so your 11 a.m. to 5 p.m. is fully covered. You get a weekly demo, a staging link to test on your own phones, and a written scope before any work starts.
Can you build logistics and dispatch software for an Illinois company?
Yes. We build dispatch boards, driver apps with proof of delivery, quoting tools and shipper portals, connected to the TMS or WMS you already run. For Life Line Ambulances, our dispatch app cut the time from request to confirmed crew from 22 minutes to 3. Logistics first releases usually land inside our 5 to 10 week range.
How do I choose an app development company in Illinois?
Ask every candidate for the same four things: published builds with named clients and measured results, the names of the people who will write your code, a written scope and price, and a clause that puts the code and accounts in your name. Compare those answers side by side. A team that will not show proof should not get the project.
Who owns the code when the app is finished?
You do. The source code, app store accounts and hosting are in your name from the start. At handover you get a recorded video walkthrough and written documentation, so any developer can pick it up later. If you want us to keep supporting the app after launch, that is optional and billed per hour.
Can I build an app with AI instead of hiring a developer?
AI tools can produce a quick prototype, and that is a fine way to test an idea. A business app that takes payments, stores customer data or collects biometrics in Illinois needs engineers who can secure it, test it on real devices and keep it running. Bring your prototype to our free call and we will tell you what it would take to ship it.
