Gritorbit: Tumbler Log

iOS app by Shadowfetch · App Store ID 6791312262 · iOS

Gritorbit is a private rock-tumbling batch lab for hobbyists who want to know exactly what is in every barrel and what happened at each stage.

Build batch cards with stone mix, barrel capacity, load weight, media, grit, start date, inspection notes, and photo references stored outside the app. Use the load workbench to compare entered barrel capacity with rock and media weight, estimate grit demand, schedule the next inspection, and preserve the full lineage from rough through polish.

Key Features

Multi-barrel batch and stage records
Rock, media, grit, and polish inventory
Load-ratio and grit-demand calculator
Stage timer plan and inspection checkpoints
Before/after result notes and batch lineage
Searchable 110-plate offline field guide
Local PDF tumble card
No account, ads, analytics, tracking, subscription, or network requirement

Results depend on your entries and equipment. Confirm material compatibility, safe handling, wastewater rules, and current tumbler guidance before each run.
