A couple of days using pebble time on android... i had to say there are not many watchapp that really useful or available for me to improve daily life. Mostly i'm using this smartwatch for notifications and changing watchfaces. A few watchapp that i think quite useful though likes..
Gallon Challenge - Help on your daily water intakes - free
Strava Starter - Start / Stop Strava activity - free
Snowy - voice assistance with limited functionality - 2.99usd
Qibla-Prayer Times and Compass - prayer times not really accurate and compas. free
Battery+ - battery monitor - free
Health - step/distance counter. Not really accurate imho.
I think this is mostly because of fewer pebble apps developer and restriction from both android and ios.
How about you guys who are wearing android wear? Does android wear apps aplenty? or using just for notification and watch faces only?
