Found this really cool and minimal Android launcher the other day.

For the past few months I've been using a side (smart)phone where I only installed Whatsapp and Spotify. Just an old Android I found in the bottom of a drawer. This has worked well for me, and Olauncher is a nice touch that makes it feel even more minimal. I sometimes go out only with the side phone or leave the main phone on my bag. As a result I get much less distracted than before.

I know this doesn't qualify as a dumphone, but I thought I could share in case someone who is not ready yet to make the switch to dumbphone finds it interesting.
