I am promoting on twitter. Every day I send a new twit with an awesome spot for going with kids. Koala Travel App got now to 100 followers!
Most of these followers come from automated social growth via Integromat scripts. I do track some relevant hashtags for my app and then follow a few people every day. Some of those will follow back. With time I'm seeing increase in organic likes from these followers which is good.
Let's see how much it takes getting to 200.
