Even after “calibrating” the bottle - which should zero out the reading when the bottle is empty, like hitting tare on a scale - the app shows 7% full. Then upon filling the bottle to the brim, the app shows 59% full. When trying to track fluid intake for specific health conditions this is just too much variance. **Developer response:** Hello Philfote, Thank you for your feedback! I am happy to tell you that we have released a new firmware that fixes inaccurate battery and water level readings. Please feel free to update and if you need further assistance please do not hesitate to contact us on hello@rebo-bottle.com Regards, Wanda ### 2/5 — Newest update kills app *2021-11-03, version 1.1.7* I just updated the app and it is now unusable. Under iOS 15.2 beta. **Developer response:** Hello Cubbie036, Thank you for your feedback! I am happy to tell you that we have released a new firmware. Please feel free to update and if you need further assistance please do not hesitate to contact us on hello@rebo-bottle.com Regards, Wanda ### 2/5 — Unit choices don’t stick and water level updates are random *2021-10-03* Seems as though the system is still quite buggy. You can’t force a rescan of the water level and it doesn’t seem to update itself reliably when you open and close the lid. Also any unit preferences made seem to get ignored. **Developer response:** Hello Rebouser, I am sorry to hear you have been experiencing this issues. Please contact us on hello@rebo-bottle.com so we can assist you with calibration instructions. Our app has been experiencing some bugs related to connectivity, our tech team has taken hands into the matter and is developing a whole new app from scratch! Once this new app is released most of the issues will be solved. We will keep you updated and thank you for your feedback. Regards, Wanda. ### 2/5 — Nice but not accurate *2021-09-12* Good idea, but only counts about every third bottle I finish **Developer response:** Hello Jhe1111, First of all apologies for the delay in our response. If you are still having problems with your bottle, please contact us on hello@rebo-bottle.com so we can provide you with assistance. On the other hand, our tech team is developing a whole new app from scratch that solves most of the bugs and issues this current app has.

Regards, Wanda. ### 2/5 — Meh.. *2021-09-04, version 1.1.4* Honestly, this is pretty disappointing. I love the concept of the bottle and the app. But, the bottle is very cheap and dents and cracks very easily. I dropped it from 4 feet and the bottom of the bottle cracked. The strap that you can hold it from ripped in half. I backed this product back in January- February of 2020, I just received it maybe a week ago. So for it to already giving me issues is pretty infuriating:/. I really wish it was better quality with all the time they spent on the bottle and technology of the cap. **Developer response:** Hello B3Arrrr, Thank you for your feedback! I am really sorry to hear you have experienced this issues. We are continuously trying to improve the quality of our REBO bottle. We have solved the lace issue and we will be happy to send you a replacement one if you wish. To do this please contact us on hello@rebo-bottle.com and we will be happy to help you! Regards, Wanda. ### 2/5 — App is not accurate *2021-08-24, version 1.1.4* I love the water bottle and its sensors appear to be mostly accurate, but unfortunately the app’s integration with Apple Health seems to be buggy. Unless I open the app first to make sure the bottle is connected (and it disconnects often), the “catch-up” data ends up duplicated in the Apple Health app anywhere between 1 and 5 times (i.e., a sip of water or 2 ounces will be added as 6 different records of 2 ounces each). It does not seem to be a problem with the bottle but rather with the app, and unfortunately makes it much less convenient. If I wanted to mess with the data manually in the Health app, I wouldn’t have purchased a smart water bottle! **Developer response:** Hello Josh, Thank your very much for your feedback! I am happy to tell you that we have released a new firmware that fixes inaccurate water level readings, hopefully this should solve your issue. Please feel free to update and if you need further assistance please do not hesitate to contact us on hello@rebo-bottle.com Regards, Wanda ### 2/5 — Not always accurate *2021-08-17, version 1.1.4* Love the bottle and it’s water tracking feature. However, recently it has been adding full bottles to my intake and saying that I am drinking 3x more than I am. Really wish there was a way to remove water. Would make tracking much easier if removing water was possible. **Developer response:** Hello David, Thank your very much for your feedback! We will pass on your suggestions to the tech team. I am happy to tell you that we have released a new firmware that fixes inaccurate water level and battery level readings. Please feel free to update and if you need further assistance please do not hesitate to contact us on hello@rebo-bottle.com Regards, Wanda ### 2/5 — Buggy *2021-08-11* When bottle fill, never reads 100% full. Doesn’t seem to update levels or what you’ve drunk very well. Or very slow. When bottle not connected to phone for whatever reason doesn’t seem like water is logged. **Developer response:** Hello Amp182, First of all apologies for the delay in our response. If you are still having problems with your bottle, please contact us on hello@rebo-bottle.com so we can provide you with assistance with your bottle calibration. On the other hand, our tech team is developing a whole new app from scratch that solves most of the bugs and issues this current app has.

Ultimately though, I have completely stopped using the app now, and I use the bottle less now as well. To start, I have been using the REBO bottle for well over a year. I have written 2 reviews on both the bottle itself and the app so far; the first I gave 2 stars, the second I gave 3 or 4 stars since I saw improvements. Here I will be reviewing the App ONLY. In short, it is much much worse. The worst it’s ever been actually. - Cluttered UI (used to be very sleek, was the best feature) - Removed feature of seeing the current water level in the bottle (an essential feature imo) - Intake measurements are less accurate (drink a whole bottle, only records 117 mL) - Get messages that “Plastic Credits” won’t be recorded due to drinking too fast (the main selling feature and innovation of this bottle doesn’t even work anymore) Positives include: - One more option for manually adding water amounts. Not great, but I noticed and I appreciate having at least one more option (now a total of 4 options from the previous 3; still can’t remove any amounts that were accidentally recorded). - The inclusion of a calendar tracker. Personally I see no benefit in it, however I can see how some might enjoy this new future. **Developer response:** Hello Barr.Levi We are happy to see you are enjoying your rebo and we appreciate your feedback! We are working on a new app that will be much more user friendly and the accuracy level in regards to water tracking and batery level will also improve significantly. We are looking forward to release the new app and you will be notified once it does! In regards to your lace breaking this issue has been caused by some problems that come from the manufacturing process. They’ve been reported and resolved. We work hard to guarantee the quality of every piece on a REBO bottle, we want you to rest assured that this won’t happen again in the future. Please contact us on hello@rebo-bottle.com so we can send you a new lace! Regards, Wanda ### 1/5 — Can’t be registered in the app *2022-09-18* Please, update SSL certificates in the authorisation service. Currently it’s impossible to login or register in the app. P.S. your App Support link in App Store is outdated as well. **Developer response:** Hello Kampone, thank you for your feedback. This issue lasted 2-3 hours are we were updating our SSL certificates but it is now resolved. Regards, Wanda. ### 1/5 — disappointing *2021-12-15* after waiting for a good while for the bottle and I get it was a feat to make it happen the app is a joke - after a few days of working well it now won’t let me back in saying my login details are incorrect repeatedly. feels like this whole thing could be a fail - hope I’m wrong … **Developer response:** Hello Bazeagle, First of all apologies for the delay in our response.

Regards, Wanda. ### 1/5 — Looks nice but doesn’t work *2021-10-14* Nice look and feel, but not accurate at all. Often tells me I’ve drunk 6+L of water when I’ve only had two full bottles. Sometimes the water level seems to update properly, but most of the time it doesn’t **Developer response:** Hello Pat-hen, I am sorry to hear you have been experiencing this issues.

Regards, Wanda. ### 1/5 — Notifications don’t match data *2021-08-11* I don’t know what time zone the app thinks I’m on but I can’t see anywhere to change it. I get sent reminders to drink at 1am and end of the day wrap ups at 4am. I also get regular messages telling me I drink too much at the same time as my bottle is saying I’ve only drunk 16% off my daily quota. Honestly, I haven’t learned a thing from having this bottle, which was the whole reason for the purchase since I’ve never been one to purchase bottled water! **Developer response:** Hello Bec, First of all apologies for the delay in our response.

If you need assistance please do contact us at hello@rebo-bottles.com. ### 2/5 — Sporadic, unreliable *2023-09-10* App is great when it works and is incredibly annoying when it doesn’t. And it doesn’t work A LOT. It randomly logs me out, doesn’t sync. The light on bottle itself isn’t very reliable either. **Developer response:** Hello Disgruntled6789, thank you for your feedback and patience, our team is aware of this disconnection issue and is working hard to release the new firmware as soon as possible to solve this issue.

I always tell you when he got some water drink special when this hot weather is coming up. Summer is around the corner. I recommend to anybody to purchase one. ### 5/5 — Good App *2022-02-23, version 1.2.2* It works well and is easy to use, I love that it reminds me when I have to drink more water! **Developer response:** Hello Cheesepuff228, Thank you so much for your feedback! we are glad you are enjoying REBO. Regards, Wanda. ### 5/5 — Really encourages me to drink more water *2022-01-04* I’m using the app with the rebo bottle (which I love - so stylish). When you fill the bottle and reset the lid you really do have to give it 10 sounds on a flat surface to register with the app. I’ve tried moving off too quickly and end up resetting again. I use the time to take a couple of deep breaths. **Developer response:** Hello Singing Deb, Thank you for your feedback, we are really happy to see you are enjoying your REBO! Stay healthy and keep cleaning the planet :) Regards, Wanda. ### 4/5 — Date *2023-05-16* Hi REBO Team The app is great, but for some reason the date is incorrect on the app. I’ll wake up in the morning and I’ll already have water intake for the day and I’ll go to the calendar and it will be the next day. I can’t manually set my time zone or location on the app. The GPS built into the bottle works fine and is correct the app just seems to be wrong and has been since I received my bottle in the first wave of the kickstarter release.

Regards, Wanda. ### 4/5 — Bugs fixed (or at least improved upon) *2022-06-01, version 1.3.1* Overall the bottle seems to be working a lot better than it was when I posted my last review. REBO has become an essential part of my day. I lost my REBO and I just stopped drinking as much water. As a result, I immediately ordered another 2. I truly love the product - I’ve been invested since day 1. Keep it up 💪🏼 **Developer response:** Hello David, Thank your very much for your feedback!

Regards, Wanda. ### 3/5 — Frustrating *2023-06-22* I love the idea and spent a lot on a REBO bottle, but it keeps on resetting the days’ streak to zero, despite my having NEVER missed a day’s hydration target. My calendar even shows this…… **Developer response:** Hello Tonksie1, Our team has been alerted of this bugged and I confirm it has now been solved! I hope your experience is better now. If not, please do contact us at hello@rebo-bottle.com Regards, Wanda ### 3/5 — App is improving *2023-06-14* The app is very buggy. Most times it doesn’t transfer from bottle. The streak does not add past one day. I do enjoy the water bottle itself. The app has got a lot potential but just lacks so much. **Developer response:** Hello LordSith13, Thank you very much for your feedback, it is beneficial for our growth.

REBO please update this app. **Developer response:** Hello Sweetooth, Thank you for your feedback. Our developers are working hard on the firmware to fix and bring new amazing features.
