Should say it's a subscription right away
4+ year old app but only one one star review should have made me suspicious, but it was free.. I thought. It's 3€/month to play light effects on your nanoleaf. There are other either free or one time purchase apps for that. The author claims that his app is much better, because the light shows are individually created. I was curious how that is supposed to work on a setup that might look absolutely different than the one where it was developed on.. But even the free trial requires you to start a subscription. No thanks.
