Looking for tracker / point database to use during bike trips / trekking / hiking?
My recommendation: Locus Map
Free version: (ads & disabled some functionalities): https://play.google.com/store/apps/details?id=menion.android.locus
Paid version: https://play.google.com/store/apps/details?id=menion.android.locus.pro
I have been using it for about 5 years and I'm really satisfied (it took me several weeks to choose the application that fits what I need)
Sometimes great functionalites are a bit hidden (for example: to import sets of tracks / points you have to zip them all together) but there are many how-tos online.
