In March a guy DMed me on Instagram. He said he was the founder of "the real AirPosture" and gave me 14 days to rename my app, or he'd take legal action.
I checked the trademark databases and couldn't find anything registered for the name, so I asked him to send whatever documentation he had. He said he'd already sent it to Apple and called me a cheap thief.
So I started counting.
AirPosture is still on the App Store under the same name, and it just turned one year old. It uses the motion sensors in your AirPods to catch you slouching and nudges you back.
For other indie devs: a DM isn't a legal notice. Check the trademark databases yourself, ask for the documents, and don't panic-rename something you've spent a year building.
