## What is Tritab Calc?

Run three calculations at once, without losing your place.

Tabs A, B and C are three independent calculators. Switch between them and the expression you were typing — and its result — stays exactly where you left it. Keep the base price in A, the price with tax in B, the discounted price in C. No more scribbling intermediate numbers on paper.

FEATURES

Three independent tabs
Switch between A, B and C with one tap. Each keeps its own state.

Calculation history
Every expression and answer is kept. Tap a history line to copy that result.

Copy and paste
Tap the result to copy or paste, press and hold to clear. Moving numbers into another app takes one tap.

Tax button
Add or remove tax with a single tap. The rate is adjustable in Settings.

Full calculator
Four operations plus square root, x squared, percent, sign toggle, parentheses and a 00 key.

Large, readable display
High contrast with big digits and automatic thousands separators.

No ads
No banners, no interstitials. Nothing interrupts a calculation.

WHERE IT HELPS

- Checking quotes and invoices with base, taxed and discounted figures side by side
- Shopping: tax-inclusive prices and comparing discounts
- Splitting a bill, comparing unit prices
- Adding up stock counts and quantities

PRIVACY

History and settings are stored only on your device. Nothing is collected, nothing is sent to a server, and no account is required.

FREE VERSION

TriTab Calc Free offers the same features with ads. Try it first, then move here for the ad-free experience.


## Version history (last 4 releases)

### 2.5 — 2026-08-19

・New app icon. It now reads as a calculator at a glance, and shows the three tabs - A, B and C.
・Lowered the minimum iOS version. The app now installs on devices that could not run it before.
・Fixed the supported-language listing. Japanese, English and Chinese now appear correctly on the App Store page.
・Rewrote the App Store description so it actually explains how the app is used.

No ads and no data collection - that has not changed. For requests or bug reports, please use the support page. This is a one-person project, so every message is read by the person who wrote the app.

### 2.01 — 2026-07-22

- New color themes: pick a soft "Pastel" look, or switch to "High contrast" for easy reading outdoors and in bright sunlight — right from Settings.
- Text is now larger and easier to read, with a "Large text" option in Settings for even bigger type.
- Refreshed the top bar and polished small details.
Thanks for using TriTab calc!
