## GreyBand Reviews in United States

### ***** "Great app for college students"
I like how GreyBand makes safety feel social instead of awkward and preachy. Most apps that deal with drinking or health feel clinical but greyband immediately gives a safe vibe while trying to have fun.
-- Priram1293, 2026-06-18

### ***** "Amazing"
The combination of all the different features is amazing and will help everyone stay accountable and proactive.
-- Reva V, 2026-06-12

### ****- "Good app"
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.
-- Kylerlegpain, 2026-06-12

### ***** "Innovative"
This app is certainly first of its kind. It’s very straightforward and beneficial. Top quality
-- xytzov, 2026-06-12

### ***** "Unique app"
I have never seen such applications before but the idea of promoting safe drinking is amazing. Hope more people will get to know this app
-- nurcone, 2026-06-10

### ***** "Necessary"
This will save lives.
-- Malcolm A-R, 2026-06-04

### ***** "Excellent Objective"
I think this app has an amazing mission. By helping promote safe and responsible drinking, it helps make the world safer. I hope this idea gains more traction in the future, as it can be beneficial to so many people.

### ***** "Great mission, great app"
Think this company is really doing some compelling work to help us rethink our habits and stay safe. Rooting for this to take off!

### ***** "The most useful app for tracking/ monitoring drinking habits."
GreyBand is honestly such a smart and useful app. I love that it helps you stay aware of your drinking while also making sure you’re being safe and responsible before driving. The accountability aspect with friends is one of my favorite features because it turns safety into something social and supportive instead of awkward. The app is super easy to use, the design is clean, and the features actually feel helpful in real-life situations. Definitely recommend for anyone who wants to have fun while still staying safe and making better decisions while drinking.
