Store description excerpt
Calk-AU puts 124 free Australian calculators in your pocket — tax, pay, mortgage, super, GST and far more — all built on the current 2025–26 ATO rates. No sign-up. No paywall. And it works 100% offline: run any calculation on the train, in a meeting or out of range. When the rates or rules change, the app updates its formulas automatically — so your numbers are always current.
