Does anyone else share my frustration when it comes to training platforms? About how all of them try to be 'the one'?

I'm on the hunt for a training platform which works with lots of devices, as much as I like Garmin connect I want something that will elegantly track workouts

My list of requirements are as follows:

• Works with multiple devices, uploading via tapirrick or manual gpx is okay as long as I can bulk upload gpx
• Tracks total miles
• Training plans
• Cycling and running
• Comparisons to how I used to perform
• I don't have a power meter so plans based on heart rate?
• Doesn't cost the earth! £10/month is too much with seemingly everything and everyone asking for that these days
