The accountability habit tracker

By the DuoShare team · Updated November 2026

An accountability habit tracker is a habit tracker where someone else can see your check-ins. That one feature makes the biggest difference in whether a habit sticks. DuoShare combines a clean daily habit tracker with friends who see your progress, shared streaks and challenges, free on iPhone.

Two jobs, one app

A habit tracker has one job: make it easy to record that you did the thing. An accountability tool has another: make sure someone else knows. Most apps only do the first. DuoShare does both on the same screen, so checking in is also telling your friend.

The features that matter

Why 66 days

A 2010 study by Phillippa Lally at University College London found it took a median of 66 days for a new daily behavior to become automatic. That is why DuoShare’s longest challenge is 66 days: long enough to make the habit yours, short enough to see the finish line.
