I think it would be cool to display a percentile rank next to the level (what percentage of all Freeletics athletes are at a lower level). That would be more fun, especially at high levels.
It would also be cool if you could display the percentile rank of the personal best within a defined group for the individual God workouts (e.g. all users doing these journeys, or all users at my level +/- 10, or all users of my gender).
