5/5 stars

Twinsi is so great and comparable to Strava, but way more fun and interactive, and very easy to navigate

Where has this been?

Moved my friends from our ‘movement accountability’ WhatsApp group to here. It’s been such an upgrade. It’s no longer just ‘accountability’ but a fun way to move and interact. 10/10 recommend

Such a cool concept

This app is just what I’ve been looking for to stay motivated. I love the visual reward of seeing my twinsi complete a workout and the social component of seeing what my friends are up to. The crew is great for that
