What's New in Dojo 21
1.1
April 13, 2026
- New milestones strip on the home screen — see every achievement at a glance and tap to jump straight to the milestones page - Your current perfect-call streak now shows on the home screen so you know what's on the line before you sit down - Reaching 21 now automatically ends your turn — no more pointless prompts on a perfect total, including across split hands - Card animations are smoother and faster, and no longer race or overlap each other - Fixed the dealer's hole card flip showing the card front on both sides instead of revealing from the back - Playing Dojo 21 no longer interrupts your music — Spotify, Apple Music, and podcasts keep playing, and the win sound (when enabled) layers on top instead of taking over - The win celebration sound is now off by default and can be toggled in Settings - The end-of-session review button now reads "Done" instead of "New Session" - Now requires iOS 26.3 for better performance and reliability
