Coinbase rewrote both their Android and iOS apps in React Native, and are happy with the end result.
My takeaways from their writeup (thread)
1. It's hard to hire good lots of native mobile engineers. Heck, this is what was probably a major trigger for their whole transition

1. (Cont'd) Coinbase had a strong React team, and not enough native engineers... and thought they could solve two problems at once. Fewer engineers, higher efficiency. blog.coinbase.com/announcing-coi…
Sounds like they might have succeeded with this (at least for now)

2. It takes a *lot* of investment to ship any mobile app at scale, RN not different. This is a post from Nov 2020 on the performance challenges their team needed to solve: blog.coinbase.com/optimizing-rea…
3. RN is not a great choice to build cross-platform *features*: it's no alternative to e.g. shared native code via KMM or C++. If you do it, going all-in is what makes most sense.
It's not a short journey: took Coinbase 2 years to pull off. blog.coinbase.com/announcing-coi…

4. You can make any technology work at scale if you have enough resources (people) to iron out its kinks. PHP to run for billions? Facebook ✅quora.com/Is-Facebook-st…. RoR at scale? Shopify ✅
Coinbase did a LOT of under the hood work with RN as well.

5. Choosing a mobile technology will significantly impact who you can (and want to hire).
Airbnb saw they were able to attract fewer native engineers & this was a contributing reason they eventually went back on RN as well medium.com/airbnb-enginee…
For Coinbase: not an issue now.

6. What do I think about the "best" mobile technology to choose? Full native? Flutter? React Native? Kotlin Multiplatform? RIBs? Something else?
I cover all these in mobileatscale.com (free as a PDF for another 2 weeks).
It's all tradeoffs: just like on the backend & web.

Tell me which is the "best" backend technology to build at scale. Go? Java? .NET? Node? Rust? RoR?
You can make it all work, even exotic ones like Erlang (e.g. Whatsapp).
The same is true for mobile frameworks. Choose based on your constraints and needs. Avoid blindly copying.
