Isa runs on the Mac, iPhone, and iPad. On the Mac you download it directly — no invite needed. On iPhone and iPad you install it through TestFlight — Apple’s beta program — after we share the TestFlight link with you. You need a Discord account on every platform — Isa uses Discord to sign you in.

​
Install on your Mac

You need macOS 26 or later and a Mac with Apple Silicon (an M-series chip). Intel Macs are not supported.
