Domestika's app is compatible and functional with Operating Systems higher than iOS 11.4 or Android 6. If your device has a lower version than the previously mentioned, unfortunately it won't be possible to download the app through your Store.
We invite you to verify if your device's Operating System can be updated. If it is possible, do so and then download the app to enjoy Domestika.
In case your Operating System can not be updated, don't worry, you can still enjoy your courses through your PC and browser.
If the issue persists or there's anything else we can help you with, do not hesitate to contact us through our contact form.
