Numbers that roll,
fields that reflow

A native text input and an animated number for React Native, built with Nitro Modules. C++ engines shared by iOS and Android.

Live: the same C++ engine that runs on your phone, compiled to WebAssembly.

On a budget phone

The example app on a Samsung Galaxy A22 (MediaTek Helio G80, 90 Hz), recorded with the phone's own screen recorder, which takes a share of its GPU while it runs. iOS runs the same JavaScript on the same engines. The benchmarks measure it against the other libraries.

Transfer
Jackpot
A trading dashboard with 48 NitroNumbers and about 210 updates a second, no re-renders; a transfer whose amount reflows as it is typed and whose payout switches currency as one change; a jackpot counted up tier by tier.
