Disable iPhone timed auto lock when an app is running? Is it possible to disable the timed auto lock on an iPhone when a particular app is running?

I use my iPhone as a GPS and I have a dock that attaches it to my bike. When im using the GPS app id like the timed auto lock to be disabled.
It is not possible to disable Auto-Lock for specific apps through iOS settings. A workaround is to manually disable Auto-Lock in settings, run the app, and then enable it again once you're done.

An app can request iOS to disable Auto-Lock. In this case, you should contact the Citymapper developer for an update to allow this.
