How it works

Five steps to showing up

Step 1 · Supporter

Set the challenge

Pick the goal, set the reward, and send an invite code.

Step 2 · Turtle

Check in daily

Log your progress and snap a photo. Your Supporter sees every check-in in real time.

Step 3 · Both

Build the Trail

Every photo lands in a private shared feed. React, cheer, and stay connected.

Step 4 · Turtle

Spin the wheel

Hit your goal and spin. One tap lands on a real reward your Supporter promised.

Step 5 · Supporter

Deliver and go again

Deliver the reward. Then start a new round or flip roles.

Why turtli

Accountability that actually feels good

No nagging

The app holds the accountability. No one has to be the bad guy.

A shared Trail

A private photo feed only the two of you can see. React and they get notified.

Gentle nudges

Reminders, supporter nudges, and reactions keep momentum going — no pressure.

Real rewards

No badges. No points. A real reward your person agreed to before the challenge started.

The spin moment

Spin the wheel yourself. The anticipation is half the fun.

Built to repeat

Finish a round and go again. Challenges reset automatically so you never stop.
