Como lo indique. Dejo el repositorio con el ejemplo de la aplicación. Quien desee ir aprendiendo Flutter, estaré dejando de poco en poco lo que voy aprendiendo. Ejemplos prácticos y sencillos. github.com/Lokocr/aprende_fl…

Pues al final la verdad es que depende mucho de tu conocimiento y que la herramienta resuelva el problema que se tiene.
Be honest As a developer, which backend framework is worth it in 2026?

7 lessons I learned building mobile apps 1. Don’t start with a huge idea. Launching a simple app in 10-15 days will teach you more than spending 6 months building a startup nobody wants. 2. Increase your number of attempts. Most successful indie developers didn’t win with their first app. The more products you ship, the more chances you create for yourself. 3. Focus on one thing. Your MVP doesn’t need 20 features. It needs one feature that solves a real problem exceptionally well. 4. Design matters more than ever. Users compare your app not only to competitors, but to the best apps on their phone. A great icon, screenshots, onboarding, and UX are not optional. 5. Use AI as leverage, not as a replacement for thinking. AI can help you build faster, but it won’t choose the right market, understand your users, or create a business for you. 6. Learn ASO and distribution. Building is only half the job. If nobody finds your app, it doesn’t matter how good it is. 7. Don’t assume you’re too late. Every year people say all good ideas are taken. Every year new categories appear and new companies are built. The best time to start was years ago. The second-best time is today.

🏳️Time to face obvious facts. iOS Dev courses are no longer viable income for me. I've been disrupted. I'm looking to join a team working on a cool iOS project (full-time or part-time contract). Remote. RT's are appreciated! DMs open.

When devs used to tell me they couldn’t reach their first $100, I didn’t believe it. A lot of them asked me where to get installs. Then I looked at their apps and honestly, it was rough. You don’t need installs, you need to fix your product and first impression ASAP: 1. Make a clean, stylish, and clear ICON. This is your very first touchpoint with the user, it matters more than you think. 2. Create high-quality SCREENSHOTS. No blurry text, no stretched devices. If you can’t do it yourself, hire a designer. 3. Build a solid ONBOARDING. Don’t cut corners here. In 3–4 steps, clearly show what your app does and why it’s useful. 4. Add a paywall AFTER onboarding. It’s simple. Offer your product confidently. In my apps, 80% of revenue comes from the first session. I don’t get why people skip this. 5. Most important: create a STEP-BY-STEP user flow. No cluttered screens. One step = one action. If you’ve done all five, then you can start thinking about user acquisition. But that’s a completely different game.

Building a high converting app onboarding flow is hard.. So I built a Claude Skill that does it for me Instead of spending hours figuring out the right questions and pain points… now it's done in 5 minutes Just point it at your codebase and it does the rest Questionnaires. Custom plans. App demos. The exact strategy used by Cal AI ($1M/mo) and Mob ($100k/mo) It's the App Onboarding Questionnaire skill and it's available on github here: github.com/adamlyttleapps/cl…
