What is Terrific Triangle?
Terrific Triangle is an educational math practice app that helps students learn and reinforce fact families through quick triangle-based drills. It is designed for learners practicing addition, subtraction, multiplication, and division, with a simple format that focuses attention on the relationship between three connected numbers. Players solve for the missing value in a triangle, track correct answers, choose difficulty settings, and optionally work against a timer for faster recall practice. The app supports individual skill building and works well for classroom reinforcement, homework practice, or extra review at home. Terrific Triangle is published by Elementary Software and is available on Apple platforms, including Macs with Apple silicon support through the App Store.

Safety overview
Status: Safe
Terrific Triangle is a straightforward educational app focused on math practice. Its expected activity is limited to normal app use, and the App Store listing states that the developer does not collect data. As with any children's learning app, install it from a trusted source and review permissions if your device prompts for anything unexpected.
Recommendation: Keep Terrific Triangle if it is used for math fact practice at school or at home. If it is no longer needed, you can remove it like any other app without affecting macOS beyond losing the app and its local settings.
