Yes, in addition to Google Play Services and the iOS App Store, Huawei AppGallery provides the prerequisite for a secure and fluid Tomorrow app experience. Push notifications, updates, and more are all provided through these services. Our app is only secure if you have downloaded it from the Play Store, iOS App Store, or Huawei AppGallery. PERIOD. The known limitations that come with missing Google Services remain with the Huawei App Gallery.
We can't take responsibility for an app you find and download elsewhere. Even if it says Tomorrow on it, and it seems to work just fine. The same applies if you change the usage restrictions of the mobile phone manufacturer - i.e. if you have carried out a "jailbreak". Please be on the safe side - it's your money, after all.
