    Frequently asked questions

    Answers to the most common questions about Triangle

    What is Triangle?

    Triangle is a free Android app that combines a task list and a habit tracker. You can share tasks and habits with friends, earn XP for completing them, and spend that XP in a reward store you set up yourself.

    How do I install it on Android?

    Download the APK from this page and open it. If Android asks, allow installs from your browser for this one file. The app checks for new versions itself and prompts you to update when one is available.

    Is Triangle free?

    Yes. There are no ads and nothing to buy.

    Do I need an account?

    Yes. You sign up with your email and a verification code, or with your Google account. That is how your tasks, habits and points are kept in sync.

    How do I share a task with a friend?

    Find your friend by username and connect with them. Then create a shared task or habit and assign it. Shared items appear in a separate Shared tab, so they stay apart from your own list.

    How do streaks work?

    A streak is the number of days in a row you have completed a habit. Each habit shows its current streak and a grid of the last 22 weeks, so you can see where you missed days.

    How do points and rewards work?

    Completing tasks and habits earns XP, which converts to coins at the rate you choose in Settings. You create your own rewards, set their price in coins, redeem them, and mark them as delivered.

    Is there an iPhone version?

    Not at the moment. Triangle is Android only.
