Together
Start a night and invite friends with a QR code. See who can still drive and who is the designated driver.

One app for your driving status, your night with friends and a few games on the side. No account, even without signal.
See at a glance whether you can drive: green, yellow or red, always also in words and with a time.
Your night as a line, with the limit drawn in and the cautious estimate as the starting point.
Beer, wine, shots or a cocktail. The app knows the serving sizes of your country. Works without signal.
The legal limit of your country, including novice drivers where that applies.
Keep track of who paid what and settle up easily at the end of the night.
Your data stays on your phone. An account is only needed to share a night together.

Cards, dice and horse racing on one phone. Water is always allowed as a forfeit.

Free, and no account needed.
iPhone: coming soon.
