These are the apps I'm using:

• Hevy for weights workout tracking ('cos app is convenient and I worked out how to access its data api for my own analysis)
• Polar Beat to record runs with phone ('cos I have a Polar Verity Sense heartrate monitor, and its audio cues are useful)
• Zwift for indoor cycling
• Strava for analysing the cardio data for running / cycling ('cos imports Polar Beat/Zwift and then has matched runs and segments)

edit: actually now found RunnerUp which seems like an awesome running app for android and is open source so giving that a go.
