## Version history (last 4 releases)

### 2 — 2026-09-09

The app has been renamed from “TriTab Calc Lite” to “TriTab Calc Flex.”

The new name better reflects the flexibility to add the features you need through optional one-time purchases. Your calculation history, settings, and purchased features remain unchanged.

### 1.6 — 2026-09-02

- Updated the App Store caption text
- Added a link to our Privacy Policy (Marketing URL)

### 1.5 — 2026-08-28

• The app was still showing "Tritab free" on the Home Screen. It now shows "TriTab Lite".

• Fixed the main display: long expressions were cut off with "…", which hid the digits you had just typed. The display now scrolls horizontally and always keeps your latest input in view. Swipe right to see the earlier part of the expression.

• History rows and the expression line now shorten from the beginning instead of the end, so you can still tell what was calculated.

• Added "More from this developer" in Settings.

• Fixed an internal counting bug.

### 1.0 — 2026-08-26

No release notes.
