Free app. No data collected, no internet needed. Super app. Just what I wanted. The official BTS app does nothing without internet access, but this app works perfectly with zero internet. Tourists don’t always have internet when they first arrive in Thailand, but they may need access to a good public transport map. This app is perfect for that. Nice job, dev. Thank you. I’m not sure if there are adverts, but I didn’t see any. Hopefully there aren’t any. I didn’t try the app with my internet switched on. If I can make a suggestion (not a complaint)… It would be nice to have more information about each station, by clicking on the map icons. As an example… National Stadium BTS gives access to MBK, but the station name does not give any clues to that. The new Grand Palace station is also a similar problem. I think that information would be helpful to tourists. I did see that some stations have information and photos, after a route has been set. But not all. Also… Bang Sue Train Station needs the name changing to its new name. But I’m sure the dev is aware of that. Thanks again. It’s nice to see that some developers are genuinely interested in helping people. Some devs seem to have forgotten about that.
