First test with cyclemeter on the way in to work.
it wasn't bad. Did a good job of recording and displays more than enough data fields. Was pleasantly surprised that it found maps despite me having it on flight mode, assume it cached them at the start. Need a longer ride to test how that works. It has loads of ride analysis, which is not such a priority, but it is good.
the map on the main screen is much better than a garmin but nothing like as good as osmand has. It does have a good map but it's on another screen. And not so easy to switch.
It worked ok with gloves.
One thing I realised is that I need to get phone on an in front mount. Currently on stem but it is too far away from the road to be looking.
I'll test it some more.
I'll also review my requirements. The main one being lap button. I only need this when I'm doing intervals and the garmin can manage those OK so maybe I don't need it. That would open up other options with better mapping, such as oruxmaps. It would also open up rwgps which has a better interface,and works with offline maps.
It might be that I end up using two or more different ones, eg cyclemeter for intervals and something else for long rides and navigating round town. I use Osmand for that at the moment and it is hard to imagine anything else will be better.
This is turning into a bit of a project, but interesting, and I'm now certain I'll have something that meets my needs better than garmin or wahoo. It will also cost less, but that's not the main priority.
