What it does

Everything you need.
Nothing you don't.

Jam Trainer is built around one idea: you should be able to sit down with any bluegrass song and have a full band ready to play it with you.

Chord Chart Editor
Build charts with sections, repeats, and arrangement order. Split measures, add ring or stop strums, set the key and capo — the editor handles it all.
5-Instrument Backing Track
Real recorded samples — not MIDI. Guitar strums, walking bass, mandolin chop, banjo rolls, and spoons, all locked together and always in tune.
Works Fully Offline
All samples cache to your device on first load. Take it to a festival campsite, a jam with no signal, anywhere — no Wi-Fi required after that.
Jam Session Sync
Share a session code with your picking circle. Everyone's chord chart follows the same song in real time on their own device — great for leading a jam or teaching beginners.
Share & Embed
Send any song to anyone with a link. They can save it to their own library or just open and play it. Embed a playable chart right on your lesson page.
Tuner & Ear Training
Chromatic tuner with drone, fingering diagrams for guitar, banjo, and mandolin, plus "Name That Chord" and Degree Trainer ear training games built in.

Built for pickers, by pickers

Practice at home.
Ready at the jam.

Jam Trainer was built by bluegrass pickers who wanted a better way to practice and keep chord charts handy at a jam. Every design decision came from actually using it — on a phone, on a tablet, with a pick in the other hand.

  • Screen stays on during playback — no tapping needed while you play through a song
  • Large tap targets work well on a phone or tablet
  • Bluetooth page-turner pedal support built in
  • Survives being briefly backgrounded when you check a text
  • Over 1,100 songs in the shared library to get you started
Guitar
Boom-chuck & full strumming · multiple chord variations · walking approach notes
Bass
Per-note chromatic recordings · alternating low notes for variation
Mandolin
Chop on the backbeat · A percussive driver helps keep you in time
Banjo
Scruggs-style rolls · correct 5th-string drone
Spoons
Because, why not?!
