TintSlate
Bring dependable formula history to every appointment with a USD 0.99 paid App Store download — no account, subscription, in-app purchase, ads, tracking, cloud dependency, or required internet connection.
TintSlate
Keep client profiles, immutable service snapshots, multi-bowl formulas, result photos, and audited corrections in a private professional ledger that stays on your device.
Every service freezes the exact formula
Record up to four bowls with brand, series, shade, role, integer-safe weight, processing time, result notes, and privacy-clean result photos.
Scaling stays exact and history stays honest
Copy a prior formula to a new target weight without rounding drift, then append corrections, photo removals, or void events instead of overwriting the original service.
Your client book remains portable
A USD 0.99 paid download includes local search, client PDF export, checksum-verified photo backup, conflict-safe merge, atomic replacement, rollback, and recovery.
Your data stays on your device
