Hydration tracker
Most people know they should drink more water — but nobody wants another app nagging them every hour. OutLast makes hydration tracking dead simple: tap when you drink, watch your streak grow, and finally build the habit.

The problem
Most water tracker apps send constant notifications that you immediately turn off — defeating the entire purpose
Counting exact ounces for every sip turns hydration into a chore instead of a habit
Generic health apps bury water logging three menus deep — so you stop tracking after day two
OutLast gives you one-tap water logging, a daily total, and a streak that keeps you consistent — no nagging required
How it works
Grab a glass, tap once. Pick a quick preset (8oz, 12oz, 16oz, 24oz) or enter a custom amount. Logged in under two seconds — faster than unscrewing the cap.
Your running total for the day is always front and center. No math, no guessing — just a clear number showing how close you are to your hydration goal.
Hit your daily water goal and your streak grows. Miss a day and it resets. Simple accountability that turns drinking enough water from a wish into a habit.
What you get
Quick presets for common amounts — 8oz, 12oz, 16oz, 24oz. Tap once and it's logged. Your water tracker should be faster than filling your glass.
Coffee and tea count toward your fluid intake — but they also affect energy and sleep. Log them alongside water to see the full hydration picture.
A consecutive-day counter that rewards hitting your hydration goal. See your current streak, longest streak, and total days at a glance.
Track energy alongside water intake. Over time, see how your hydration habits affect how you feel — and find your personal sweet spot.
The science
What people say
“I've tried every water tracker app out there. They all spam you with reminders until you delete them. OutLast just lets me tap when I drink and shows my streak. That's all I needed.”
“I started tracking water and coffee together and realized I was drinking 4 cups of coffee but barely 40oz of water. Seeing the numbers side by side changed my habits completely.”
“The streak is what keeps me going. I don't want to break my chain, so I actually finish my water every day now. Went from maybe 30oz to consistently hitting 80oz.”
