Otto: Drink Less

Otto is the friendly otter who feels every drink with you — and helps you drink less. Quitting or cutting back on alcohol is hard, but you don't have to do it alone. Otto reacts in real time as you log drinks, giving you an instant, honest, and surprisingly sweet mirror for your choices. No lectures, no judgment — just a companion who's rooting for you. Log a drink in one tap. Beer, wine, cocktails, shots, or seltzers — pick it and you're done. Otto shifts through five expressive states as your estimated blood alcohol rises, so you always have a friendly visual cue for how you're doing. See your live BAC estimate. Using the Widmark formula and your personal body stats, Otto shows an estimated blood alcohol level that decays over time, plus a sober countdown. This is an informational estimate only — never use it to decide whether it's safe to drive. Build streaks that actually mean something. Track alcohol-free days, chase your best streak, and watch your calendar fill with mini-Otto faces and mint dots for every clean day. Progress you can actually see. Watch your savings add up. Otto compares your drinking against your personal baseline to show real money saved and drinks avoided — proof that cutting back pays off, literally. Set it up your way. A quick, judgment-free onboarding lets you choose your goal — quit entirely or just cut back — along with your weekly limit, body stats, and drink cost, so everything Otto shows you is personal to you. Your data stays yours. No accounts, no cloud, no one watching. Everything lives privately on your device. Whether you're aiming for one dry week or a whole new relationship with alcohol, Otto is the small, encouraging nudge that makes the journey feel lighter. Download Otto and start your streak today.
