4.1

April 21, 2026

A new version is available! Update now to get the latest content and important bug fixes.

User reviews

Didn’t work

I followed the instructions to the letter, even got my countdown to set off, and hey presto, thirteen miles in I’m told I’ve just completed my first mile. To be fair once it had kicked in I was wishing it hadn’t because the motivational stuff was cringy and woeful.

App is Glitchy

A number of us sent message boosts in for our runner and they didn’t receive them at all. No email after either. Nothing. Very disappointed.

This app sucks

It doesn’t work

Don’t work at all

The app failed to load at any point during the marathon so we had no idea where the person we were supporting was which made being there impossible and frustrating

Easy to use but too slow

Useful interface but on London marathon 26 the app failed to show the person I was supporting progress. The mobile network being slow is also a problem during
busy events.
