Product details

Built around one clear job.

Each product begins with a practical problem and removes everything that does not help solve it.

Every line remains visible and editable, so a correction does not mean starting over.

Percentage, tax, margin and everyday conversions are close at hand.

Named calculation sheets and searchable history stay on the device.

A one-time Pro purchase permanently removes ads and unlocks unlimited sheets plus CSV and PDF export.

Version history

Meaningful changes, recorded clearly with the newest version first.

Version1.0.215 July 2026
Clearer sheets, visible Pro and carefully placed calculator advertising.
- The former “tapes” are now called calculation sheets throughout all 12 interface languages.
- The one-time Pro offer is visible from the main screens instead of being hidden only in Settings.
- From the fourth eligible session, the free version may show one consent-aware banner in Calculator, Tools and History. The calculator banner stays separate from the keypad and is hidden when screen space is tight.
- Pro permanently removes ads and unlocks unlimited named calculation sheets plus CSV and PDF export; it remains a one-time purchase with no subscription.
Version1.0.115 July 2026
A recognisable calculator icon and complete localization.
- The launcher icon and Google Play visuals were redesigned to communicate the calculator purpose more clearly.
- The interface was completed in 12 languages, including Estonian and excluding Russian.
- Free-version banners were delayed until the fourth app session and kept away from the primary calculation flow.
Version1.0.012 July 2026
The first ClearTape release.
- A precise everyday calculator with live results, percentage logic and scientific functions.
- Searchable local history, editable calculation sheets and practical conversion tools preserve useful work.
- A restorable one-time Pro purchase removes advertising without a subscription.
