Takes so long to load

The app takes 20 seconds or more each time I try to open it. Please improve the efficiency of the app, thanks. Also, showing daily data usage instead of monthly will be useful.

App review

App does not work on iOS 13.4.1. App does not open, and keeps loading and nothing happens. In the rare occasion it does, it keeps telling me the app needs to be upgraded when I literally just downloaded it. Please fix.

Developer Response ,

Hihi, please do try to reinstall and see if it is possible to access. If not please do contact us on live chat during working hours so we can help. - Mabel
