### 1/5 — Didn’t work

*2026-05-12*

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.

### 1/5 — App is Glitchy

*2026-05-03*

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.

### 1/5 — This app sucks

*2026-04-29*

It doesn’t work

### 1/5 — Don’t work at all

*2026-04-27*

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

### 2/5 — Easy to use but too slow

*2026-04-27*

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.

### 1/5 — Shame it didn’t work

*2026-04-26*

Spent most of the race trying to get this to work but no signal wherever we were standing

### 1/5 — Useless - not accurate

*2026-04-26*

This app is as much use as a chocolate teapot! Runners are not tracked accurately, so as a charity, we missed many of the runners that were running to support us. Could do better!!

### 1/5 — Temperamental

*2026-04-26*

Worked for about five minutes and then you couldn’t use it.

### 1/5 — Junk

*2026-04-26*

Worst app i’ve ever used

### 1/5 — Appalling

*2026-04-26*

This is one of the worst apps I have ever seen. It simply doesn’t work. Over the 2.5 hours so far it has only “relocated” my tracked participant twice - just abysmal. 

I have to wonder if they are using the British Airways software team!
