About this app
Tumbler Buddy helps you run your rock tumbler like a pro—not a guesswork experiment. Track each stage, remember what’s in the barrel, and get nudges when it’s time for the next grit or polish. WHO IT’S FOR • Home tumbling & lapidary hobbyists • Anyone juggling multiple batches, barrels, or long multi-week runs • People who want fewer “wait, what step am I on?” moments WHAT YOU GET • Stage & batch tracking built around real tumbling workflows—not generic task lists • Simple, focused views so you can update progress in seconds • Reminders you can lean on when life gets busy • Works great offline; optional cloud features when you want them (where available) PREMIUM (IF APPLICABLE) Unlock premium for advanced coaching, syncing, and upgrades that power users ask for—exact list is shown in the app before you subscribe. PRIVACY-FIRST MINDSET We keep the experience practical: you stay in control of your data choices. See in-app links for Privacy Policy and Terms. Tumbler Buddy is built for people who love rocks, polish, and repeatable results. If that’s you, welcome to the buddy that holds the whole process together. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
