首次连接

1. 唤醒划船机，确保未被其他 App 占用。
2. 在 App 中选择蓝牙设备，名称通常贴在蓝牙发射盒标签上。
3. 按提示匀速划 5 桨，App 识别到 5 桨后会自动完成测试。

计数不准或不兼容

• 先重新测试，并远离其他蓝牙设备或原厂 App。
• 在“设置 → 诊断”点击“上传诊断日志（邮件）”。
• 在邮件中补充划船机整机照片、蓝牙接收盒和标签照片，以及实际划桨数与 App 记录数。

App 不会自动发送日志；只有你在邮件窗口确认后才会发出。

免费版与专业版

免费版不限训练次数，每次最长 5 分钟，到时自动结束并保存。专业版为一次购买，去除单次训练时间限制并解锁未来所有功能。请先完成兼容性测试并确认计数准确。

更换设备或重装后，可在 App 设置页恢复购买。退款由 Apple 处理，可前往 Apple 报告问题 申请，是否批准由 Apple 决定。

First connection

1. Wake the rowing machine and make sure no other app is connected.
2. Select its Bluetooth device in the app. The name is usually printed on the transmitter label.
3. Row 5 steady strokes. The test completes automatically after the app detects all 5.

Incorrect count or incompatible device

• Run the test again and disconnect the manufacturer's app or other nearby Bluetooth clients.
• Open Settings → Diagnostics and tap Email diagnostic log.
• Add photos of the complete rowing machine, Bluetooth receiver, and label, plus the actual and detected stroke counts.

The app never sends logs automatically. They leave the app only after you confirm the email.

Free and Pro

The free version allows unlimited workouts of up to five minutes each and saves automatically at the limit. Pro is a one-time purchase that removes the per-workout time limit and unlocks future features. Complete compatibility testing and verify stroke accuracy before buying.

You can restore your purchase from Settings after reinstalling or changing devices. Apple handles refunds; request one at Report a Problem. Approval is Apple's decision.
