I first got my PÜL water bottle about a year ago and everything worked perfectly. I lost my water bottle and got it replaced months later, and now the app is completely useless. You can’t actually track toward any personal goal because the app just disregards any manually input goals, and randomly changes the goal to arbitrary numbers throughout the day. I’ve deactivated all of the factors that would make the goal auto-adjust and it still just does not work. The percentage means nothing. This app is actually terrible and I was probably better off not replacing the bottle. ### 1/5 — Hardware is there, software is not *2025-01-24* The one star rating here comes only after multiple emails to support and submitted feedback items on their website. The actual bottle and hardware is well designed compared to past bottles I've tried. I love that the tracking is based on the flow through the straw, and there is no measuring process needed after filling the bottle. Problems: - The bottle flashes to remind you to drink. However I like to keep the bottle on my bedside table when sleeping, and there is no setting to disable flashing during certain hours. That's fine, expecting this feature would be above and beyond in my opinion (going from a 4 star to a 5 star product). However that means my only option is to entirely turn off Hydration Reminders. Problem is: this setting doesn't work. Whenever I change the setting, navigate away from the settings page and come back it has reverted to being on. - The Apple Health sync is a fantastic concept, and it's great to see how much my hydration needs change as a result of exertion. However the app seems to only sync from Apple Health once a day or not at all on some days. Almost every time I do a large workout later in the day it never syncs to the app. It's a shame because it's so close to amazing. - One time my app completely wiped my entire state. I needed to create a new profile and account from scratch. And it lost all my data. - One time my bottle got in a state where it was flashing every two minutes and eventually stopped syncing to the app. I think starting to charge it fixed it. No response from Pul on ANY of my requests for help. This product is so close to fantastic, O really wish they'd get their act together. ### 3/5 — Bugs Galore *2024-10-21* The cap itself is phenomenal and the integration to Fitbit works so overall I am happy. After working for a couple of weeks, the app began to exhibit several bugs that I emailed support about. The first is that my schedule for when I’m awake and sleep changes by itself, making it seem as though I am overdue for hydration at any given time throughout the day. Thus, my cap does not adaptively alert me when I am actually behind on my water intake versus being up to speed on my goal. Often times it increases my daily goal by large amount due to a temperature glitch. It’s currently 50° but somehow the app is saying that it’s 212°F so it’s adding an extreme number of additional ounces. overall, the cap is great, but the app needs a lot of work and attention. However, it doesn’t seem the developers care to fix these minor bugs that seem to have been an ongoing issue for months based on other comments and reviews. ### 1/5 — The worst app ever made *2024-07-29* Horrible product, horrible app, horrible company. If you are about to download this to work with your smart cap, DON’T - and return the smart cap. ### 1/5 — New app messed everything up *2024-06-11* New app version came out beginning of February and was riddled with bugs. Made my experience a total mess by losing all my past drinking data and not keeping my wake and sleep times among other issues. A new version came out mid February still full of bugs and instability. Support seemed to care at first, but then no word from them since the last app version which is almost 3 weeks ago. Loved this smart cap but now it’s complete trash with no word of when all the issues will be resolved. ### 5/5 — Solid app *2024-01-26* Very happy with this app so far. Clean and easy to keep track of my water intake. Wish there was a widget for iOS though! ### 1/5 — Worthless *2023-11-28* The app DOES NOT WORK. I cant even get past “calculating your baseline” so i cant even link my bottle. Bottle glows when drinking and the top pulses green when its plugged in like its trying to pair so I know the bottle is fine. For the hundred dollars I spent on this bottle, the app not working is unacceptable. It renders the bottle useless and it is now just a ridiculously expensive, normal water bottle. PLEASE fix the app! Ive already sent in feedback with screenshots and screen recordings with no follow up. The concept is amazing and if the app worked I would be thrilled. ### 1/5 — Nice bottle, app is buggy *2023-11-25* I just got my bottle and was psyched to start using it. I ran into issues with the app very early on onboarding. I have been trying to setup my account and have been running into issues for ‘calculating the baseline’. It won’t let me move forward and the loading screen appears to get stuck. I was really looking forward to using this but now I’m just bummed. ### 5/5 — I love my new PüL! *2023-09-05* I love my new PüL! I find the entire idea of it to be very convenient. I've been using a squeeze bottle for many years, and lately have developed some thumb issues because of it. One week into the PüL and my hands already feel so much better. And I can't believe how easy it is to get water from. A very simple sip goes a long way, and you don't have to tilt the bottle at all. It basically does all of the work for you. And the light-up reminders are great for when I'm busy at work and would otherwise neglect to drink any water. So far since switching bottles, I'm taking in an additional 20 ounces per day! The app is also really easy to use. I personally don't have any issues with it whatsoever. I'm not sure why some of these other reviews are so low, because it has been flawless for me since Day 1. It syncs in real time and seems impossibly accurate as far as the data it collects. Seriously, I'm not easily impressed at all, but I am with my new PüL. Oh, and the slider keeps the mouthpiece clean all day long! I'm loving this thing!! ### 1/5 — Love the idea, but it’s unreliable *2023-09-01, version 2.2.7* The app just doesn’t work well with integrations. I love the idea of my goal changing based on my workouts and the weather, but each time I reinstall the app, set up the integration with apple health, it works for about 1 day and then just doesn’t read any data. ## Frequently asked questions about PÜL ### What does PÜL do?
