Connect your watch, band, ring and scale to Gesynd.

Gesynd brings the values of your devices together, even from several at once. Every device comes in directly via Bluetooth, through Health Connect or both ways, just as the device allows.

Connection ways

Directly via Bluetooth, through Health Connect or combined.

The ways do not exclude each other. Gesynd fetches values directly from your devices and also reads what is in Health Connect, for example from your ring. In return, Gesynd writes your values to Health Connect, so your other apps can use them.

  • Supported

    Directly via Bluetooth

    Gesynd connects to your device itself, no vendor app needed. For watches and bands whose model Gesynd knows, for example the Knauermann PRO 4 and selected Polar watches and bands, for Polar sensors with live heart rate during workouts, and for devices with the Bluetooth standard for health devices, such as chest straps, scales, blood pressure and blood glucose monitors and thermometers.

  • Supported

    Through Health Connect

    Your device's app stores its values in Health Connect by Google, Gesynd reads them there, older values included, and writes its own values there. That way every device whose app writes to Health Connect joins in.

  • Coming

    Through your vendor account

    For devices whose values only live in the vendor's online account. You decide whether to connect it.

Device types

Which device reaches Gesynd which way.

Plus every other device whose app writes to Health Connect. You can use several devices at once. If they measure the same thing, you choose per value which device counts.

  • Watches

    Directly via Bluetooth if Gesynd knows the model, for example the Knauermann PRO 4 and the Polar Vantage V3, Vantage M3, Grit X2 and Grit X2 Pro. Every other watch comes in through Health Connect, also in addition to the direct connection.

  • Fitness bands

    Directly via Bluetooth if Gesynd knows the model, for example Polar Loop and Polar 360, otherwise through Health Connect if your band's app writes there.

  • Rings

    Through Health Connect, for example sleep and heart rate from your ring's app.

  • Chest straps

    Directly via Bluetooth with the Bluetooth standard for heart rate, plus Polar H10 and H9. During a workout in Gesynd you see your pulse live, also from the Polar arm sensors OH1 and Verity Sense.

  • Scales

    Directly via Bluetooth with the Bluetooth standard for scales, Gesynd takes over every measurement. Or through Health Connect.

  • Blood pressure monitors

    Directly via Bluetooth with the Bluetooth standard for blood pressure, or through Health Connect. You can also enter single readings by hand.

  • Blood glucose monitors

    Directly via Bluetooth with the Bluetooth standard for blood glucose. You can also enter values by hand, in mg/dL or mmol/L.

  • Thermometers

    Directly via Bluetooth with the Bluetooth standard for thermometers, or through Health Connect.

  • Other devices

    If your device's app writes to Health Connect, Gesynd reads the values there.

Directly via Bluetooth

Connect your smartwatch directly, without the vendor app.

Gesynd connects directly to your watch via Bluetooth and reads its values. You no longer need the vendor app for that. With the Knauermann PRO 4 and identical watches, you also set up the watch in Gesynd.

  • Knauermann PRO 4Tested with Gesynd: read values and set up the watch.
  • PolarGesynd reads the watches Vantage V3, Vantage M3, Grit X2 and Grit X2 Pro and the bands Loop and Polar 360 with their history. Ignite 3, Pacer and Pacer Pro and the sensors H10, H9, OH1 and Verity Sense deliver their heart rate live during a workout in Gesynd. Gesynd changes and deletes nothing on your Polar device.
  • Identical watches and bandsModels that otherwise run with the same vendor app use the same connection. Which values you get depends on what your device measures.
  • More devicesMore direct connections will follow. Until then, their values come in through Health Connect.
