Give everyone a turn at your next jazz jam session. SessionHost helps hosts choose who plays next, balance the instruments, and track how many songs each musician has played. Spend less time organizing and more time enjoying the music. BUILD THE NEXT LINEUP Register players and their instruments, then start a session. After each song, mark it played to generate the next lineup. SessionHost considers instrument roles and completed play counts to help spread playing opportunities more evenly. KEEP PLAYERS ON STAGE Pin a musician to keep them on the same instrument for following songs until unpinned. Edit the current lineup and choose which registered instrument each player will play. FOLLOW THE FLOW OF YOUR SESSION See total and per-instrument play counts. Add musicians, let them sit out, or adjust the front-line limit as the session unfolds. Register up to three instruments per player in order of preference and add custom instruments to suit your group. PICK UP WHERE YOU LEFT OFF Keep several sessions in progress, revisit completed sessions, and reuse previous participants and session settings. Add song titles to keep a record of what you played. Made for iPhone and iPad, with English and Japanese interfaces. No account required. Session data is saved on your device, and session management works offline. Banner ads require an internet connection.

Verdict
The clearest difference is ads: Jazz Time Trainer at none against SessionHost's shown. Jazz Time Trainer also leads on iOS requirement (13.0 vs 16.4). SessionHost's advantage is update cadence (every 2 days vs every 4 days). On price, in-app purchases and device support there is nothing between them.
