Description
Track your rock tumbling journey from rough to polished with Tumbler Timer Pro — the essential companion app for rockhounds and lapidary enthusiasts.
Whether you're running one tumbler or several, Tumbler Timer Pro keeps you organized with precision stage tracking, timely notifications, and detailed logging so you never miss a grit change again.
KEY FEATURES
◆ MULTI-BATCH TRACKING
Run multiple tumblers simultaneously. Each batch gets its own timeline, progress tracking, and stage management. See all your active batches at a glance on the dashboard.
◆ SMART STAGE TIMERS
Set custom durations for each grit stage — from hours to weeks. The app calculates your timeline and shows exactly when each stage completes.
◆ STAGE COMPLETION ALERTS
Get notified the moment a stage finishes. No more guessing or checking your calendar. Tumbler Timer Pro alerts you so your rocks get the attention they need, right on time.
◆ QUICK LOG CHECKS
Tap to log common maintenance actions: added water, added grit, checked sounds, paused tumbler, and more. Add custom notes for detailed record-keeping.
◆ FLEXIBLE RECIPES
Start with the standard 4-step process or customize your own recipe. Save your preferred stage configurations as defaults. Create and manage custom recipes for different rock types.
◆ GRIT STAGE PRESETS
Choose from standard presets:
• Standard 4-Step (Coarse → Medium → Pre-Polish → Polish)
• Quick 3-Step for softer materials
• Extended 5-Step for extra refinement
◆ ROCK IDENTIFICATION GUIDE
Built-in reference guide with hardness ratings and tumbling tips for popular materials including agate, jasper, obsidian, quartz, and more.
◆ BATCH HISTORY
Review completed batches anytime. Restart a previous batch with one tap to tumble similar material again.
◆ PHOTO DOCUMENTATION
Add cover photos to each batch to track your rocks' transformation from rough to polished.
