1. The apps "Explore city Metro" for other systems are 10x better.Was doing ok with this app until I realised HK MTR map was out of date and did not show recent extension to the networki've used this app the first time i went to hongkong (on a diy tour) and its VERY VERY VERY HELPFUL.work only once.
2. for now this application is not works on huawei phonesQuick, easy to use and clear information.
3. If you just want to quickly check the train status, this will instead blast a full screen video add at full volume, which can't be dismissed.
4. Must have app when visiting Hong KongEasy to use and very helpful for navigating the city using the MTR.
5. For a foreigner new to Hong Kong it made getting around very seamless indeed.This app sucks as a subway route planner.
6. Ads are VERY intrusive.on huawei phones this application only works 1 time.
7. It wastes your roaming data on its spam instead of giving you any useful information.
8. when clear settings through the application manager.
9. Map view for route very helpful.
10. then it will get caught on the red screen.
11. The functionality is terrible and usage is mediocre.
