I didn't expect a QR code to be the most engaging feature in my app

3,000 people found HabitHook organically. and the feature they engage with most? a QR code.

not a leaderboard. not streaks. a QR code that lets you invite someone into a habit challenge instantly — no links, no signups friction, just scan and you're in together.

turns out consistency gets a lot easier when someone else is doing it with you.

built HabitHook to be simple and clean — no bloat, no guilt trips. but this one feature keeps surprising me with how much people actually use it.

if you try it, especially the group challenges — tell me what works and what needs fixing.

building this solo so every piece of feedback goes directly into the next update.
