### 5/5 — Best app ever!

*2024-10-10, version 1.7.6*

This makes my life so much easier. 
This app is so simple but brilliant. I’m on a mobility scooter, as go faster than walking trying to work out how long it would take me to get somewhere is a nightmare! Especially it you can’t use stairs. I always used to go really early as I couldn’t always have time to work it out and spend my time twiddling my thumbs by ending up going too early. 
This app is just perfect.
