The iPad beta is live on TestFlight now — iPhone is coming. Try the web app right now, or grab the source.
Meridiem Now
Native, touch-first. In beta on TestFlight now; App Store coming soon.
iPhone: coming soon. This build is designed for iPad — it installs on iPhone too, but shows the same layout stretched down. We’re holding a real iPhone app until it can do its actual job: setting up Meridiem One instantly over an on-screen QR code. That lands once Meridiem One’s own software is further along.
Free · Meridiem Pro from $2.99/mo, $29.99/yr, or $99.99 once.
