Frequently Asked Questions
Q: How much money can I make from a mobile app in 2025?
A: It depends on your niche and monetization:
- Successful subscription apps: $10K-100K+ monthly (after 1-2 years)
- Marketplace/commission apps: $5K-50K monthly (faster to monetize)
- Ad-based apps: $1K-20K monthly (requires 100K+ active users)
- Average successful app makes $10K-500K monthly after 2 years
Q: Should I build for iOS or Android first?
A: Build cross-platform with React Native to get both at once. If you MUST choose one:
- iOS: If targeting US/Europe, higher-income users, B2B
- Android: If targeting global market, emerging economies
Q: How do I validate my app idea before building?
A: Follow these steps:
- Create a landing page describing your app (use Carrd, Webflow)
- Run Google/Facebook ads targeting your audience ($100-500)
- Collect email signups
- If you get 100+ signups with <$5 cost-per-signup = validated
- Interview 10-20 potential users to understand pain points
- Build MVP only after validation

A: Not necessarily, but it helps:
- With tech co-founder: Lower cost, faster iterations, better decisions
- Without tech co-founder: Hire agency or dev team, maintain control, easier to pivot
Q: What's the biggest mistake first-time app entrepreneurs make?
A: Building features users don't want. Start with ONE core feature that solves ONE specific problem. Validate it. Then expand. Don't build your dream app v1.0—build the smallest thing people will pay for, then iterate.

A: Tried and tested channels:
- Product Hunt launch
- Reddit communities (provide value first)
- Facebook/LinkedIn groups
- Content marketing (SEO blogs like this one)
