User reviews

App not connecting to lights on iOS

The lights are not pairing with the app now. I have reset the lights, deleted and reinstalled the app. It finds the lights but they will not light up to finish pairing to show battery status.

Bit Clunky, needs more time in the oven

It does what it says on the tin but lacks basic logical features like a widget for quick access to power on/off, opening the app everytime is silly. Also grouping of lights by bike… the idea here is great, but they need to think more about the app in use and why app connectivity is utilised by their customers

ペアリング

購入後デバイスを追加に表示されず、レビューを見てもペアリングできない方がたくさんいらっしゃったので諦めていましたが、電源ボタンを10秒間長押しするとライトが10回点滅して、(ペアリング解除)その後はアプリに表示されペアリングできました。トラブルシューティングに記載した方がいいと思いました。

お困りの方

当初iPhone13miniでペアリングできませんでしたが、一度Android機(当方はタブレットを使用)でペアリングしたのち、PCでファームウェアアップデートした所、iPhone13 miniでも無事にペアリングできました。
お困りの方はお試しください。

Sync won’t Sync

Just bought a sync core. Doesn’t sync. The app hasn’t been updated in 2 years. I should have read the reviews before buying it.
