TumbleLedger

Keep every rock-tumbling batch organized without an account or server.

TumbleLedger is an offline record for hobby rock tumblers. Create reusable tumbler and barrel entries, start a batch, and record its current stage, grit or media amount, due date, notes, and a stage photo. Complete a stage to move the batch forward and review its history.

Use Today to see due and overdue batches. Optional local reminders help you remember the next stage change. Data is saved automatically on your device. JSON export and import are available in the free version.

Free includes one reusable barrel, one active batch, full stage history, reminders, JSON backup and restore, and one photo for the current stage.

An optional lifetime Premium purchase unlocks unlimited reusable barrels, unlimited active batches, and multiple photos per stage. The price shown in the app is supplied by Google Play. There is no subscription and no advertising.

Photo and notification access is requested only when you choose the related feature.
