How to Choose an App Development Company: 12 Questions to Ask Before You Sign
Choosing an app developer comes down to four things: proof they have shipped apps like yours, a written fixed scope, clear ownership of the code and accounts, and a team you can actually reach. The twelve questions below expose the differences between firms in one call, whether you are comparing agencies in Bergen County, Manhattan, or overseas.
The 12 questions
- 1. Which apps like mine have you shipped, and can I download them? Screenshots are not proof. A live App Store or Google Play listing is.
- 2. Will I get a written scope with a fixed price before work starts? If the answer is an hourly estimate, the risk is yours.
- 3. Who owns the code, the app store accounts, and the backend? The only acceptable answer is you, from day one, in writing.
- 4. Who exactly will do the work, and where are they? Meet the engineers, not just the salesperson. Ask which time zone they work in.
- 5. Do you build the backend and admin tools, or just the app? An app without its backend is half a product.
- 6. Do you handle App Store and Google Play submission, including rejections? Submission is a skill. Rejections happen. Someone must own them.
- 7. What stack do you recommend for my app, and why? A firm that always answers with the same framework is selling its habit, not your solution.
- 8. How will I see progress? The right answer is a build on your phone every sprint, not a demo at the end.
- 9. What happens after launch? Ask what the warranty period is and what support costs afterward.
- 10. How do you handle sensitive data? Payments, health information, and minors' data each have rules. Listen for specifics, not reassurance.
- 11. What is not included in this price? Store fees, hosting, third-party services, and content are common gaps.
- 12. Can I speak to two recent clients? Then actually call them.
Red flags that end the conversation
- No live apps you can download, or portfolio pieces that turn out to be templates
- A price before any scoping conversation
- Code or accounts that stay in the developer's name until final payment or forever
- The person you meet disappears after the sale and you cannot name your engineer
- Reviews that all appeared in the same month or read alike; the FTC now bans fake reviews and testimonials outright
- Pressure to sign a long retainer before the first version exists
- No mention of testing on real devices or of store submission
How to compare quotes fairly
Two quotes for the same app can differ by three times and both be honest, because they include different things. Put every quote into the same grid before you compare the totals.
| Item | What to ask each vendor to state |
|---|---|
| Scope | List of screens and features, and what is explicitly excluded |
| Platforms | iOS, Android, or both; native or cross-platform |
| Backend | Included or not; who hosts it and in whose account |
| Admin tools | Do you get a panel to manage users, content, and orders? |
| Testing | Real-device testing, beta program, security review |
| Store submission | Included, including rejections and resubmission? |
| Ownership | Code repository, store accounts, domain, and backend in your name |
| Warranty | How many days of fixes after launch |
| Support | Retainer or hourly rate afterward |
| Payment | Milestones tied to deliverables, not calendar dates |
Local, remote, or offshore
| Local (NJ / NYC) | Remote US | Offshore | |
|---|---|---|---|
| Hourly cost | Mid to high | Mid | Low |
| Hours to ship | Fewer, with senior engineers | Fewer | Often more, with rework |
| Communication | Same hours, in-person possible | Same or near time zone | Overnight cycles |
| Legal recourse and IP | US contracts, enforceable | US contracts | Harder to enforce |
| Best when | The app matters to revenue and you want a partner you can meet | You are comfortable fully remote | Budget is the only constraint and you can manage the project yourself |
We are based in Teaneck, NJ and Queens, NY, work Eastern hours, and meet clients in person across Bergen County, the five boroughs, and Fairfield County. That is the middle column with the option of the first.
Checking reviews and references
Read reviews on more than one platform (Google, Clutch, DesignRush, LinkedIn) and look for specifics: what was built, what went wrong, how it was handled. A perfect record with no detail is less credible than a strong record with one honest complaint. Then call two references and ask the questions the review did not answer: Did they hit the dates? What did the change requests cost? Would you hire them again?
Contract terms to insist on
- Intellectual property assignment to your company for all custom code, effective on payment of each milestone
- Written scope attached to the contract, with a change-request process and prices
- Milestones tied to deliverables you can test
- Warranty period for defects after launch
- Access to the code repository and all accounts throughout the project, not at the end
- Exit clause that lets you leave with the work completed to date
