Store description excerpt
$4.99. ONCE. FOREVER. No subscription. No ads. No "free trial" that auto-charges. Built for people who think with numbers. • Edit any step in your tape — everything below auto-recalculates. • Scientific mode in one tap (no rotating). • Multi-sheet workflows: separate boards for groceries, contracts, projects. • Variables: define `tax = 0.08` and reuse across calculations. • Aggregate bar: sum, average, max, min, count, std on selected lines. • Currency snapshots (100+ fiat + Bitcoin, offline) and unit conversion (length, weight, temperature, speed, data, energy, pressure, time). • Time math: today + 30 days, 3h45min + 1h30min, time-zone conversion. • PDF / CSV export with multipage table layout. • Widgets — small, medium, large, lock screen. • Live Activities + Dynamic Island for long edit sessions. • Works perfectly on iPhone and iPad. • iCloud sync across all your Apple devices. • 100% offline, 100% private — zero analytics, zero ads.
