About this app

All for your music — a specialized music practice kit for everyday training.

dinnib brings tuning, timing, rhythm training, chord practice, and recording into one app built for musicians. Start with free essentials. Sign in to practice and record with a monthly allowance, then unlock Unlimited or subscribe to Premium when you need more.

Companion single-purpose apps (MetronTune, Dinkeys, Beat Caliper, Shift Tape, Rhythm Stick, Tempo Glass, and Chord Paper) are also available separately on Google Play. Purchases do not transfer between the suite and those apps.

FREE — NO ACCOUNT REQUIRED
• Tuner+ — 1-cent precision chromatic tuning for guitar, bass, ukulele, violin family, piano, and more; multi-instrument and multi-tune modes
• Metronome+ — high-accuracy tempo with flexible pattern combos (time signatures, 4-bar cycle layouts, subdivisions, and accents) and clear visual beats—not just a flat click
• Dinkeys — tap, explore tones, and capture ideas on a responsive practice pad

SIGN IN TO PRACTICE AND RECORD
• Beat Caliper — see the beats you play with ~4 ms onset precision
• Rhythm Stick — five levels; presets and random Generate (billions of patterns in theory); train and test by tap
• Tempo Glass — guided then silent timing drills; build your inner tempo sense
• Chord Paper — full 12-TET chord library: read, listen, train, test and master
• Shift Tape — record, organize, and play back your sessions; import audio from your files
• My Records — practice calendar and history across tools
• Shared monthly practice sessions — 15 practice sessions per calendar month for paid practice tools combined (device timezone). Dinkeys recording requires sign-in and does not use practice days.

UNLIMITED (ONE-TIME PURCHASE)
Buy Unlimited once to permanently remove the monthly practice-sessions limit for Beat Caliper, Rhythm Stick, Tempo Glass, Chord Paper, Shift Tape, and future paid tools under the same unlock. Unlimited does not include cloud backup.

dinnib PREMIUM (SUBSCRIPTION)
Premium includes Unlimited on your account, plus cloud backup for Shift Tape, Beat Caliper, and Dinkeys while your subscription is active. Cloud backup is subject to usage limits described in the app and our Terms of Service.

There is no free trial. Payment is charged when you subscribe (where offered). You can purchase Unlimited if you only need unlimited practice without cloud backup.
