In general, our indoor cycling app has very low hardware requirements and communicates with many devices via Bluetooth.
The app runs on Windows PCs, MacOS computers, iOS tablets/iPads and Android tablets.
In general, the app also runs on smartphones, but we recommend a display of >10 inches for a fulfilling display.
Let us know which device you train with. This helps us expand the list.
Of course you can also train with the software without a smart roller trainer, but then you have to set the resistance on your device yourself. You can also use the icTrainer software for spinning, for example.


















Bluetooth vs. ANT+
Important: The software only connects to the devices via Bluetooth LE and not via ANT+ (exception: heart rate chest straps under Windows and MacOS).
Advantage: No ANT+ dongle is required for the connection to a tablet, laptop or computer. You can continue to measure all your training performance in parallel via ANT+ on your normal fitness tracker (bike computer, fitness watch, etc.) and also transfer it to the app of your choice and we communicate with the devices in parallel via BluetoothLE.
So we don’t force you into a different cosmos for your training evaluations;
If you have a roller trainer that only supports ANT+, you can use it with the following ANT+-BLE converter dongle, for example: NPE Cable
You then no longer need a USB/USB-C/USB micro/Lightning ANT+ dongle and can connect the roller, power, speed, cadence and heart rate monitor via BluetoothLE.
Disadvantage: You need an iOS tablet/smartphone for the initial and one-time configuration of the NPE Cable with your ANT+ devices. And the shipping and customs fees are about the same as the NPE Cable price itself. You should look for a European distributor if you want to buy the dongle.
As a rule of thumb: If other third-party training programs/apps can communicate with the devices via Bluetooth, icTrainer can do the same.
