Apologies, I have a serious question! I'm fairly new to this but originally started using cyclemeter on my phone, I then upgraded this so I could transfer the data to Strava on my laptop. Is it possible to just use Strava on my phone and not use cyclemeter at all? Are there any advantages to this, in particular around battery usage or accuracy? I don't have any issues with what I currently do except for longer rides I do have battery problems (i have a very old iphone and do look a the football scores when out so that may be the real problem).
