🔥 5 React Native mistakes that cost more to fix later
After working on multiple mobile products, I keep seeing the same problems:
1️⃣ Using global state for everything
Not every screen needs Redux. Keep local state local.
2️⃣ Ignoring list performance
A badly configured FlatList can make a simple app feel broken. Memoization, pagination and stable keys matter.
3️⃣ Building before defining navigation
Auth flow, onboarding, tabs, deep links — decide this early. Refactoring navigation later gets painful fast.
4️⃣ Treating Firebase as “just a backend”
Firestore structure, indexes, security rules and listeners need architecture too. Otherwise costs and complexity grow quickly.
5️⃣ Testing only on one device
An app can feel perfect on a new iPhone and terrible on a mid-range Android.
React Native lets you move fast.
Good architecture lets you keep moving fast after version 1.0. 🚀

For a product like Habitly, I would judge the intro by how quickly it explains the value, as well as how it looks. Is this for onboarding or a promotional video?
2.8M views for a launch video that should be too slow for X.
75 seconds.
No voiceover.
No fast cuts.
Framer turned a product release into an event.
The video is slow, but it never feels empty.
First, Framer teases the new interface. Then we see the Agent redesign a page, create responsive versions, write a code component, and work across the product.
Framer can spend 10 seconds building curiosity because the post explains the launch and the audience already knows the product.
Smaller brands should show the result sooner.
But the lesson is worth copying: show the real product, use one visual style, and give every scene one clear job.
P.S. This isn’t my work. I study the best and apply what I learn to the Launch Videos I create for my clients ❤️🔥
I always appreciate videos like this. Thanks for the share, Nikita!
