Most apps that deal with drinking or health feel clinical but greyband immediately gives a safe vibe while trying to have fun. ### 5/5 — Amazing *2026-06-12* The combination of all the different features is amazing and will help everyone stay accountable and proactive. ### 4/5 — Good app *2026-06-12* GreyBand has a really strong concept, especially with its focus on safety through real-time BAC tracking and the ability to alert friends when needed. It's a useful idea that can genuinely help people make better decisions while still enjoying social situations. The design is clean and easy to look at, but it's not immediately clear how everything works when you first open the app. A better onboarding experience or clearer introduction to key features would make it much more intuitive. Overall, it's a promising app with a lot of potential, just needs a bit more clarity upfront. ### 5/5 — Innovative *2026-06-12* This app is certainly first of its kind.
