アプリ OKOK アプリ ユーザーマニュアル

The provided manual for the OKOK App and Body Fat Scale does not contain specific troubleshooting steps for the screen light not turning on. It primarily focuses on app installation, Bluetooth connection, and data synchronization. Since you've already tried changing the batteries, which is a common first step for power-related issues, and the manual doesn't offer further guidance on display problems, I recommend checking the manufacturer's website or contacting their customer support directly for more specific troubleshooting or repair options.

The provided manual for the OKOKアプリ does not explicitly detail subscription sharing or multi-device licensing policies. However, based on standard app store practices and the app's functionality, here is how you can typically manage this:

• Shared Account: If you both log in using the exact same credentials (email/phone number and password) on both phones, you should both have access to the premium features. The app supports multiple user profiles under one account to track individual data.
• ファミリー共有: If you are using separate accounts, check if the subscription was purchased via the Apple App Store or Google Play Store. Both platforms offer "Family Sharing" or "Family Library" features, though the app developer must specifically enable this for in-app subscriptions.
• デバイスバインディング: The manual mentions "binding" the scale to the app via Bluetooth. While the scale can sync to multiple phones, the premium subscription is usually tied to the ユーザーアカウント rather than the physical scale hardware.

If logging into the same account on your phone does not activate the features, we recommend contacting the app developer's support directly through the "Feedback" or "About" section within the app to confirm their specific policy on multi-device subscriptions.

If the OKOK app is stuck on an advertisement screen, you can try the following troubleshooting steps to restore functionality:

• Force Close the App: Completely close the app from your phone's multitasking/recent apps view and relaunch it.
• Check for a Skip Button: Look closely at the corners of the screen (often the top right) for a small "Skip" or "X" button that may be difficult to see.
• アプリのキャッシュをクリア: Go to your phone's Settings > Apps > OKOK and select "Clear Cache." This can often resolve interface glitches.
• アプリを再インストールします。 If the issue persists, uninstall the OKOK app and download it again using the QR code in the manual or via your device's official app store.
• インターネット接続を確認してください: Sometimes ads fail to load or close properly due to a weak connection; try switching between Wi-Fi and mobile data.

Once the app is open, ensure your ブルートゥース is enabled on your phone to synchronize data with the scale as described in the manual.
