## Version history (last 5 releases)

### 1.5 — 2025-04-02

More fun "reward" images and animations. Bug fixes and even better compatibility with the latest devices.

### 1.4 — 2024-02-09

Improved support for Dynamic Island and the iPhone 15 series. The preferences now provide a more granular control over the difficulty level of problems being presented...  and an explanation of which fact families are included with each difficulty level.

### 1.3.5 — 2023-11-26

Support for iOS 17

### 1.3.4 — 2022-02-25

Minor cosmetic and performance improvements.

### 1.3.3 — 2022-02-20

Terrific Triangles is a bit more nimble. But that's not all.  We added a couple animations to make getting a correct answer just a little bit more fun. We reduced the system requirements so that it works on iOS 10 again... in case you are using older devices. (iPhone 5 is good to go!)  And we made a few minor cosmetic improvements and bug fixes.
