Since 2015 I am publishing stuff into Apple's App Store.
The best way to check the world of train tracks (Open Railway Map) on your mobile device.
A very simplistic bar code scanner. Ready to scan qr, aztec, ean and a lot more codes.
Another app to check your mobile data usage - but this one comes pretty lightweight.
Just in case you want to reach out to me... make sure to use one of the given methods.
