Rummaging through Google Play store I have found many apps I never heard of. Some are useful and some are plain trash. Anyway, I am curious have you found any interesting app?
There is a free Android app that may be of use/interest to users of older IBM/Lenovo PC models. You can see a demo of it at www.pscfg.com/lenlookpro.mp4
Okay, this might be completely random, but one app I discovered recently is called iNaturalist. I haven't played with it for long, but I've enjoyed it thus far. It helps you identify plants and animals in the nature.
