-## Motivation
+## Future updates
+- Other Czech cities
+  - Back-end implementation is ready for additional cities, problem relies in obtaining [GTFS data](https://developers.google.com/transit/gtfs). In Czechia, only City of Brno provides pure GTFS data to public. Other cities' GTFS data are a bit harder to obtain, as CHAPS insists on using obsolete technology (see [this thread](https://www.infoprovsechny.cz/request/pristup_ke_skutecne_strojove_zpr)). 
+  - Solution however might be to indeed use `ftp://ftp.cisjr.cz` and convert JDF data to GTFS using [jdf2gtfs](https://www.infoprovsechny.cz/request/pristup_ke_skutecne_strojove_zpr) script by [@masopust](https://github.com/masopust)
+- Android shortcut?
+  - As author does not posses any Android device, he will not be developing any Android front-end client soon. However, it should be very simple (as iOS shortcut is). If any Android user implements this in shareable form, please let the author know via GitHub issues.
+- Other features
+  - If you have any suggestion, please add a feature request via GitHub issues.
