What's New in Gulpo

1.0.5

October 21, 2026

- Made for iPhone Duo. Use Gulpo one-handed on the outer display, or open it up and let the water fill the larger inner display. Keep Gulpo open beside another app, and watch the water move as you open and close iPhone Duo. - Meet Glance. Prop iPhone Duo up on your desk and Gulpo becomes a calm water display you can read from across the room: your day's level edge to edge, the number large, and a clock in the corner counting down to your next sip. Fallen behind and gone quiet? It shows how long it's been since your last drink. Drag the number onto an amount to log it, and watch the water splash as it lands. A small reward for every drink. - Fix a drink in seconds. Logged the wrong drink, amount or time? Tap it, swipe it, or press and hold to change it. - Log from the Lock Screen. The new Log a Drink widget adds an amount, a full glass or a sip from your bottle without opening the app. Show the amount, or keep just the icon. - Log More, a new control, takes you straight to the logger from Control Centre, the Lock Screen or the Action button. - Not feeling well? Tap your goal at the top of the screen, then the new symptoms button, and mark a fever, nausea and more. Today's goal rises to match, with no trip to Settings, and tomorrow starts fresh. - Gulpo now speaks Japanese, Korean, Simplified Chinese, Traditional Chinese and German. - Various fixes and UI polish. Thanks a lot for all the love and your wonderful feedback.

User reviews

Mostly excellent although…

Very visual app with beautiful graphics, widgets, voice support etc but I cannot find a way to edit the time that a drink was taken. With other hydration apps you can go into the log and amend the time, so you don’t have to log a drink at the moment you take it but can catch up afterwards.

Beautiful UI & does what it needs to.

Wanted to pace my drinking and this was the nicest drinking tracker I saw, and it’s got a beautiful UI. Love the animations and the inputs are good. Will be upgrading when I am able to as I really want this to stay! Thank you for making this - there are so many trackers out there but this is exactly what I needed and it fits all my needs.

Good luck with everything! Its hard to get attention to smaller apps especially hidden gems like these so I hope this can help more people find yours.

Made me actually hit my water goals!

Gulpo is one most thoughtful designed apps, that first helps you understand your hydration habits, then teaches you that hydration is not about drinking 500ml in one go, it’s about taking small sips throughout the day.

As stunning as you’d expect

I never really write reviews on here, but i settled onto this app from Twitter and was absolutely impressed by how beautifully designed this app is. It’s extremely simple to use and the amount of details i was able to pick up on made this app feel so good to use. Definitely the best designed water tracker on the App Store.

Best UI in any app for hydration period.

This is gotta be the smoothest and most satisfying app to use to log your drinks and water. Genuinely wish the best for the dev, just hope an Apple Watch app is released soon 🙏
