Good app but need improvement

Im trying with iPhone 5 (iOS 8.4) and Zeaplus Band (E06). Need improvement and better stability like MiFit (Xiaomi Miband). Need better bluetooth range and sms/whatsup notification (like MiBand Utility tweak). Please fix because a lot of time the smartband loose data info and I need to sync again. Even with last update the blutooth range is too short.
