The company you choose affects your app’s quality, cost, and timeline more than any single technology decision. A little diligence up front saves a lot later.
Step 1: Know what you need
Write a one-page brief: the problem, the users, must-have features, platforms, and budget range. A clear brief gets comparable quotes. If you are still shaping the idea, start with how to validate your app idea.
Step 2: Shortlist 3 to 5 companies
Look for teams that have built apps like yours. Review their portfolio, live apps in the stores, and ratings. Check their own website: is it fast, clear, and professional?
Step 3: Ask the right questions
- Experience: Have you built something similar? Can I try it and speak to the client?
- Team: Who will actually work on my project, and will they stay on it?
- Process: How do you plan, design, build, and test? How often will I see working software?
- Communication: Who is my contact, and how fast do you respond?
- Change: How do you handle new ideas mid-project?
- Ownership: Do I own the code, designs, and store accounts when we finish?
- After launch: What support and maintenance do you offer, and what does it cost?
Step 4: Compare proposals fairly
| Compare | Why it matters |
|---|---|
| Scope and deliverables | Two $60,000 quotes can include very different work |
| Design and testing included? | They are often cut from cheap quotes |
| Timeline and milestones | Shows how realistic the plan is |
| Payment terms | Tie payments to delivered milestones |
| Support after launch | Apps need ongoing care |
Red flags
- No relevant portfolio or references.
- Vague or missing written scope.
- A price far below the rest, or promises that sound too good to be true.
- Pressure to sign quickly.
- Reluctance to give you ownership of your code and accounts.
- No plan for testing, security, or maintenance.
Freelancer, agency, or in-house?
Freelancers can be great for small, well-defined work. Agencies provide a full team and continuity. In-house teams make sense once the product is core to your business and you can support the hiring. Many companies start with a partner and bring work in-house later.
A simple scorecard for comparing companies
Score each shortlisted company from 1 to 5 on the criteria below, then multiply by the weight that matches your priorities. A spreadsheet is enough.
| Criteria | Suggested weight | What good looks like |
|---|---|---|
| Relevant shipped work | 25% | Live apps similar in size and complexity, in the stores |
| Process clarity | 20% | Clear stages, demos every sprint, written scope |
| Team and continuity | 15% | Named people, low turnover, backup if someone leaves |
| Communication | 15% | Fast, honest, proactive answers during the sales process |
| Quality and security practices | 10% | Automated tests, code review, security awareness |
| Price and terms | 10% | Fair, transparent, tied to deliverables |
| Support after launch | 5% | Defined care plan and response times |
Notice that price is not first. The cheapest option that has to be rebuilt costs more than a fair quote done well.
What to put in your brief
A one-page brief gets better, comparable proposals:
- Business goal and how you will measure success.
- Target users and where they are.
- Must-have features and a short wish list.
- Platforms and any required integrations.
- Compliance needs (payments, health data, children).
- Timeline and budget range. Sharing a range is helpful; it lets teams propose the right solution.
- How you will decide and by when.
Questions for reference calls
Ask past clients, not just the company:
- Was the project on time and on budget? If not, why, and how was it handled?
- How did the team respond when something went wrong?
- Did the people you met in sales do the work?
- How was the quality of the app after launch (crashes, reviews)?
- Would you hire them again, and for what kind of project?
Contract terms worth checking
| Term | What to look for |
|---|---|
| Ownership | You own the code, designs, and content on payment. No hidden license fees |
| Accounts | Apple, Google, cloud, and analytics accounts are in your name |
| Milestones and payments | Payments follow delivered, accepted work, not just calendar dates |
| Change process | How changes are estimated, approved, and billed |
| Warranty | A defined period to fix defects at no charge |
| Handover | Documentation and a way to continue with another team |
| Confidentiality and IP | Your ideas and data are protected |
If a company resists any of these, ask why. Fair partners rarely do.
Before you sign
Read the contract for ownership, payment milestones, acceptance criteria, change process, confidentiality, and post-launch support. Then see how the cost and timeline compare with typical ranges.
Frequently asked questions
What questions should I ask an app developer?
Ask about similar projects, who will actually work on yours, how often you will see progress, how testing and changes are handled, who owns the code, and what support looks like after launch.
Should I hire a freelancer or an agency?
Freelancers suit small, well-defined tasks. Agencies offer a full team (strategy, design, development, QA) and continuity if one person is unavailable.
What are red flags when hiring an app company?
No relevant work to show, vague scope, pressure to sign quickly, refusal to share code ownership, no testing plan, and quotes far below everyone else's.
How much should a fixed-price contract include?
A written scope, milestones and payment schedule, acceptance criteria, change process, code and design ownership, and post-launch support terms.
