   These people refuse to respond to a loyal customer!. If I had to go back when I purchased 2 $100 bottles from this company who absolutely refuses to reply to my 4 emails I’ve now sent them I would have never bought them. They will not help a customer who has done nothing wrong. I just need help getting into my app since it doesn’t recognize me when I try to sign in. Do not purchase from this company you will be sorry you ever did. No customer service help whatsoever. I wrote a Better Business Bureau complaint and multiple Google Reviews. Can’t stand ignorance.

   Failure to update. I got the waterbottle to document my water intake. And it’s failing to update when I turn on the app

3. ★★★★★subscription and paid restrictions

   App doesn’t sync. I bought the new PRO 2 model on Wednesday. It worked for the first few hours, but since Thursday, every single drink log has been stuck in a perpetual spinning loop. The app clearly reads the exact ounces from the bottle via Bluetooth, but the data never actually finalizes, leaving my daily progress total sitting at 0 ounces day after day. I have tried every single troubleshooting method available: force-closing the app, toggling Bluetooth and Wi-Fi, completely disabling the Apple Find My integration, performing a hardware soft reset on the puck sensor using a pin, and ensuring all software versions are fully updated. Absolutely nothing works to push the backlog through. The only remaining workaround is to delete the stuck logs and manually enter my water intake, which completely defeats the purpose of paying a premium for an automated smart bottle. The hardware is nice, but the app is completely broken. Save your money until they release a functional firmware patch.

   Hardware & Software. The software has room for improvement in user interface design, for example, having a search function rather than scrolling, endlessly through different drink options would make data entry a lot easier. Where my main issue comes with this app is in the integration with its hardware. I began having Bluetooth issues with my phone, which prevented me from using some important apps, such as the key to my car, and all the other Bluetooth connected apps I rely on for other tracking purposes. The problem turned out to be the HidrateSpark. I didn’t realize this until after I replaced my one year-old phone, thinking it had a significant issue that cost much to repair as a new phone would cost me. Hardware Failure The bottle comes with a three month warranty. Just before the three months expired my unit stopped functioning. I contacted customer service and after multiple back-and-forth sessions, they determined the unit was broken as I had said. A month and a half later I still have not received the replacement part. There have been no company in initiated updates only responses to my email asking for a status. The good news is they appreciate my patience. The bad news is I have been waiting almost as long for the replacement part as I had the working bottle to begin with.

   Annoying AF. Not a huge fan of annoying me to drink water lol

6. ★★★★★cross-device sync is unreliable

   It’s been down hill. I’ve had Hidrate bottles for years, but since I got the HidrateSpark Pro 2, I’ve had so many issues synchronizing between my phone and the bottle. The app crashes or gets stuck. I have to repeatedly recalibrate the bottle. However, the issues don’t occur with the earlier versions of the bottle. It’s so disappointing.

7. ★★★★★negative experience without a specific reason· unspecific

   App functionality. Every single time I open the app, it goes to Nov 21, 2024. Water does not track and the only fix is a force close.

8. ★★★★★negative experience without a specific reason· unspecific

   App bugs out. I love this water bottle and it helps me when it works. But the app will suddenly stops working. I’ve had it two months and this has happened twice. Never get a response from the makers for help!! I’m frustrated since this bottle was expensive!!!

9. ★★★★★crashes, freezes and errors

   Buggy, doesn’t work. The app is so buggy, and the hardware probably too. I’ve never gotten a notification on the bottle when I’m behind drinking water. Tons of other issues too.

10. ★★★★★negative experience without a specific reason· unspecific

    Never syncs. I used to love this water bottle! I have tried reaching out multiple times since buying a new Hidrate Spark Pro 2 and no help. My water bottle will not sync no matter what I have tried. Why not fix the issue that so many are having with the Pro2…syncing the water. It is the reason people buy the product!

11. ★★★★★negative experience without a specific reason· unspecific

    Don’t buy. Old version better. You have to open the app to get stuff to update. The older cups would update automatically. So this new version is pointless. Unless you’re opening the app all the time you have no idea how much you have drank. What’s the point of the wishes if they don’t update unless you open the app????

12. ★★★★★negative experience without a specific reason· unspecific

    Puck does not work.. Puck does not work. Customer Service makes you jump through way too many hoops before replacing the puck. I am still jumping through hoops for a terri le puck. It’s exhausting and frustrating. I have bought 3 Pro 2 and 1 Pro 1. I don’t think it’s worth it anymore.

13. ★★★★★negative experience without a specific reason· unspecific

    Horrible. This app is horrible it constantly has issues connecting to the bottle, updating the water, and basically doing anything it should actually do.

14. ★★★★★subscription and paid restrictions

    Stopped syncing completely. The syncing after launch of the 2.0 bottles got better, then worse. Now, it hasn’t synced at all for a week. When opening the app, the sync icon just spins and spins. I’ve reset this bottle so many times now. This is the most expensive beta test I’ve ever bought into. I should have known where the company’s priorities were by how anti-consumer their subscription is. I regret buying these bottles for my family and friends.

15. ★★★★★crashes, freezes and errors

    Support is poor. There is no way to tell for sure whether the app is buggy or the bottle isn’t working. Support is poor “do this and this and this and see if it works” kind of thing. There has to be better products than this out there.

16. ★★★★★subscription and paid restrictions

    What happened???. My Spark 2 disconnected from my phone without warning, is not synching via Bluetooth, and I see I’m not the only one. These aren’t cheap, I’ve paid for the annual app, and it’s useless. And now I have an expensive water vessel that does nothing, I need to manually enter water, and it STILL doesn’t log it.

17. ★★★★★negative experience without a specific reason· unspecific

    Sync and battery level. My HidrateSpark pro 2 won’t sync at all. I want to track my intake but, when it won’t sync I can’t. When you spend so much money on something and it doesn’t wanna work it’s so frustrating. Please fix this issue. Also if when I’m charging the water bottle if you could put a battery level so I don’t have to unplug it to see what the battery status is while charging. That would also be helpful.

18. ★★★★★negative experience without a specific reason· unspecific

    Terrible app!. When setting new pro2 up you can’t even click on finish button and you have to force close app. Bottle doesn’t even sync!!! Returning this garbage.

19. ★★★★★crashes, freezes and errors

    App is buggy. When adding a bottle and it walks you through the steps, when you get to the step where it shows the finish button, the button doesn’t actually do anything. I have to force quit the app for it to go away. I calibrated the bottle and I’ve been drinking out of it but it will not sync with the app. The bottle flashes and tells me it registered it but the app is not functioning properly. I have to manually add water daily. I tried restarting the phone, updating the app, I removed and added the bottle back. Nothing is working in the app.

20. ★★★★★crashes, freezes and errors

    Broken Smart Sync. After four bottles, the PRO 2 is a massive disappointment because the redesigned tracking fails to record most of my water intake. Hidrate claims the bottle stores days of data, but in reality, my sips never register unless I manually force a sync by making the bottle glow. This glitchy connection makes the widgets useless and leaves my progress out of date, which defeats the entire purpose of a smart tracker. It’s frustrating to see advanced technology used as a talking point to cover up a product that simply doesn't work as well as the older models.

21. ★★★★★negative experience without a specific reason· unspecific

    App freezes. I've been adding hydration manually because the app freezes when it gets to “finish” when I try to add the bottle. I click the button after syncing the bottle and it never clears the screen

22. ★★★★★negative experience without a specific reason· unspecific

    Lacks Service. App and product lack service support

23. ★★★★★negative experience without a specific reason· unspecific

    Keeps disconnection. The app worked well for about a year, but now it keeps disconnecting. Unfortunately, to reconnect it, it takes no exaggeration 25 times, and the next morning it disconnects again.

24. ★★★★★negative experience without a specific reason· unspecific

    Terrible app. Disconnects constantly

25. ★★★★★negative experience without a specific reason· unspecific

    Sucks. It defaults to tea for some stupid reason

26. ★★★★★negative experience without a specific reason· unspecific

    Bottle doesn’t sync. Just got a new Pro2. The app consistently says the bottle needs to be recalibrated and doesn’t sync with the bottle.

27. ★★★★★negative experience without a specific reason· unspecific

    Stoped tracking. A month in and it stoped automatically tracking.

28. ★★★★★subscription and paid restrictions

    Subscription for a water bottle. Subscription for a water bottle?! Come on. This app is so buggy and nothing improves. I can’t even imagine paying a subscription for something that can’t even open to the right screen. I know this is a critical review, but if you charge a premium, your service should be premium! Make it worth something. Edit: Developer sends me a generic response… might as well just not respond at all.

29. ★★★★★negative experience without a specific reason· unspecific

    Completely crashing all the time. The app keeps on crashing

30. ★★★★★negative experience without a specific reason· unspecific

    Syncing breaks constantly. Let me start by saying that when it’s working, I love this product. And it did work consistently for me for quite some time. However, since the iOS 26 update in October of 2025, syncing routinely breaks (most often after charging). I’ve spoken with the support team, and their suggestions SOMETIMES work, but four months with no fix? Yikes. Would not suggest purchasing a bottle until they sort out the issues that it seems most of their customers are experiencing.
