A glass that fills as you drink.
Set a daily goal and watch the water rise with every cup. An hour-by-hour strip shows when you drank, a banner lets you know when it's been a while, and weather sip tips suggest a little extra on hot days.

Features
Everything you drink, in one clear glass.
Drinkyin is quick enough to use for every cup and thoughtful enough to keep using. Here's what's inside.
Log in one tap.
Quick picks are ordered by what you actually drink, so the buttons stay put and your thumb learns them. Or search, scan a barcode, or make your own.
Know what's in the cup.
Calories, sugar, caffeine and sodium are saved with every log, scaled to how much you really drank. Set targets for any of 16 nutrients and get one heads-up when a drink would take you over.
A collection of everything you've tried.
Every drink you log lands in your Collection. Star favorites, and keep a Wishlist of drinks you've spotted — log one and it moves over on its own.
Routines that log themselves.
Same latte at 8:00 every weekday? Make it a routine and it's logged for you. Reminders only nudge you inside the hours you choose.
Your cups count too.
Add your favorite mug, tumbler or bottle. Drinkyin works out how often you use each one, how much it has poured and what it costs per use — straight from your logs.
Friends who remind you to drink.
Follow each other and either of you can send a 💧. It shows up as a card on their home screen — no chat, no pressure. Your profile stays private until you switch it on.
Your week at a glance.
A month calendar of every day you've logged, and a weekly report with your totals and the drink you reached for most.
Themes
Make it yours.
Glass is the default — the look of this page. Ten more are a tap away in Settings → Appearance, and every one has a light and a dark mode.
Privacy
Private by design, not by setting.
What you drink says a lot about you. Drinkyin started as a notebook that lives on your phone, and it still works like one — the cloud is optional.
No account needed
Without an account, your drink log never leaves your device. Sign in only if you want sync across devices, a profile or friends.
Works offline
Log on a plane or in a basement bar. Your data is saved on the device first, every time.
We never store where you are
Your location is used in the moment — to find shops nearby or fetch the weather. A check-in can name a café; it never carries coordinates.
You choose what's public
Your profile is private until you turn it on. Then each section, and each check-in, has its own switch.
Shops see totals, never you
Businesses only get counts of public check-ins, added up on our server. Never a single person's record.
No ads, no trackers
No advertising or analytics SDKs in the app, and no cookies or trackers on this site. Delete your account from inside the app, any time.
For cafés, bars & brandsBETA
Put your menu where people log their drinks.
A Business Account turns Drinkyin into a shop window: your drinks show up when people search, and your page shows your full menu and locations.
- Your own shop pageMenu, locations, a phone number and a map link.
- A verified badgeAfter a quick ownership check through your website, a social account or your listed phone number.
- Insights without surveillanceSee how often your menu gets logged — as totals, never as people.
Then Settings → Business Account.

FAQ
Good questions.
Do I need an account?
No. Everything works on your device without one, and your drink log stays there. Create an account only if you want your logs on more than one device, a public profile, or friends who can remind you to drink.
What can I log?
Anything you drink: water, sparkling water, tea, coffee, milk, probiotic drinks, juice, sports and energy drinks, soda, beer and other alcohol. Search more than 1,000 drinks, scan a barcode (product data from Open Food Facts), or add your own.
Is there an iPhone or Android app?
The web app installs to your Home Screen today and works offline. Native apps for iPhone and Android are on the way.
Can Drinkyin warn me about allergens?
If you add allergy or "watch out for" notes in Settings, Drinkyin points out drinks that may contain them. It's for reference only: no note doesn't mean a drink is free of something, so always read the label. Drinkyin isn't medical advice.
How do I delete my data?
In the app, go to Settings → Account → Delete account to remove your account and everything synced to it. To clear a single device, use Settings → Data. More detail is on the account deletion page.
