Rouvy, but above all Rouvy AR is the new experience for indoor training for cycling. Actually the app is not very recent but during 2020 it has undergone deep upgrades.

BigRingVR is very similar to Rouvy AR, but the most interesting things I found it has been the possibly to use Custom Workout during your course.
