Questions to Ask Potential Developers
About Their Experience
- Can you show me 3-5 apps you've built that are similar to mine?
- What challenges did you face in those projects and how did you solve them?
- How long have you been developing mobile apps?
- What's your experience with [specific technology you need]?
About Your Project
- Based on my requirements, what approach would you recommend?
- What potential challenges do you foresee?
- How would you estimate the timeline for this project?
- What information do you need from me to give an accurate quote?
About Working Together
- How do you communicate with clients during the project?
- How often will I receive updates or demos?
- What happens if I need changes during development?
- Do you provide maintenance and support after launch?
Red Flags to Avoid
Warning Signs: Watch out for these indicators of potentially problematic developers.
- No portfolio or references: Every experienced developer should have work to show
- Extremely low prices: If it seems too good to be true, it probably is
- Vague answers: Good developers ask detailed questions and give specific answers
- No contract or agreement: Professional developers always document terms
- Promises unrealistic timelines: Quality app development takes time
- Poor communication: If they're slow to respond before hiring, it won't improve after
- No testing process: QA should be part of any professional workflow
- Won't share code samples: Be wary if they can't demonstrate coding ability
The Vetting Process
Step 1: Review Their Portfolio
Download and use apps they've built. Check if they're polished, bug-free, and have good reviews on the App Store.
Step 2: Check References
Ask for 2-3 references from past clients. Prepare specific questions about their experience working with the developer.
Step 3: Technical Assessment
If you're not technical, consider having a technical advisor review their code samples or conduct a brief technical interview.
Step 4: Start with a Small Project
Before committing to a full project, consider a paid trial project. This lets both parties evaluate the working relationship.
Pro Tip: Pay for a discovery/planning phase before committing to full development. This gives you detailed specs and lets you evaluate the developer's approach with minimal risk.
Freelancer vs Agency: Which to Choose?
Choose a Freelancer When:
- You have a smaller budget
- Your project is straightforward
- You want direct communication with the developer
- You need flexibility and quick pivots
Choose an Agency When:
- You need multiple skill sets (design, development, backend)
- Your project is large and complex
- You need a team that can scale
- You want project management handled for you
Protecting Yourself
- Use contracts: Always have a written agreement covering scope, timeline, payment, and IP ownership
- Milestone payments: Never pay 100% upfront. Use milestone-based payments tied to deliverables
- Escrow services: Use platform escrow when possible for added protection
- Regular check-ins: Stay involved and review progress frequently
- Own your accounts: Make sure you control the App Store developer account and source code repository
Building a Long-Term Relationship
The best outcomes come from long-term developer relationships. Once you find a reliable developer:
- Pay fairly and on time
- Communicate clearly and respectfully
- Trust their expertise while sharing your vision
- Plan for ongoing maintenance and updates
- Provide referrals for great work
