LUCY® Smart Cap

Sadly, I used my points for my Lucy SmartCap, and unfortunately the 1 L bottle that I use at work that I specifically saved up my points to get the Lucy cap for … it didn’t fit. However, the one time I did use it, it was really easy to use, and The instructions are actually very clear. If I get another 1 L bottle I may very well purchase this item. However, I have the limited edition London bottle that is no longer made as there isn’t a London shop anymore so I doubt I’m going to stop using it any time soon. LOL The customer service representative who helped me work out why it wasn’t fitting (my bottle was produced prior to 2020) was exceedingly helpful and arrange my return immediately. This in no way was waterdrops fault.

So far I’m really enjoying this! Definitely helping to remind me to drink more and great to see it automatically tracking to the app.

I love my Lucy cap. I had the Larq before buying the Lucy cap but the ability to keep track of my hydration was crucial for me.

So helpful and very cool! Only downside is it’s hard to clean because it can’t be submerged in water, but the benefits far outweigh the downside! Holds its charge all day.

May 24, 2023

So smart! Does exactly what you need it to as well as looking great!

In love with my LUCY! The reminder flash in handy so I don't forget to keep dinking instead of trying to make up for the whole day before going to bed.

Very useful as I don't drink a lot of water, so it reminds me.

Amazing piece to the waterdrop collection. No more forgetting to log drinks

December 28, 2022

It takes a time getting used to it. Once I understood how it works it’s a great tool to help remember to drink at regular times intervals

December 19, 2022

All go so far

Smart cap is great at reminding you to drink, recording how much you have drink and purifying the water, I love it and it’s definitely motivating me to drink more

December 06, 2022

The Lucy was delivered while I was at work, so never got to try it until early evening, that was a mistake, haha. I drank 2 litres of drops over couple hrs as I tested the Lucy out. Lucy worked brilliantly, but word of warning don’t drink that amount drops before bed, I was up half the night using the toilet. But I love the drops and Lucy, would definitely recommend.

October 24, 2022

Incredible product, very useful aid to drink more water, excellent cleansing function and aesthetically pleasing!! Have recommended to many, thank you Waterdrop!

September 24, 2022

Love Lucy she helps me with my hydration.

August 09, 2022

Great but if technology but too a bit to get it connected

July 25, 2022

Love love love Lucy 🥰 had a few teething problems but very easy to sort with the help of waterdrop customer service.

July 20, 2022

I am so glad i purchased Lucy. It had made my monitoring so much easier now. if you dont have one i suggest you get one. I havnt regretted it.

July 18, 2022

I sincerely think I did a good investment- it does do what it advertises and I feel more confident in having my water every single day

July 16, 2022

Loving my Lucy smart cap working for me love using the glass clear bottle most as I think goes so well with the white Lucy cap and is able to see how much water is in the bottle plus great when using the UVC blue light Cleaning function. Which i love so pretty at night awesome I don't have to Manually input the water amount/intake which i dont mind doing but its cool Lucy does it for you it is easier. Lastly they flashing reminders are cool hoping other Lucy colours come at some point or when a new version Lucy cap 2.0 comes too.

July 16, 2022

What an amazing product. Keeps track of your water consumption. It’s works really well and is pretty easy to set-up. The app is easy to use and seems pretty accurate.

July 15, 2022

Lucy had helped me drink more water. So glad this invention came about especially at the right time. Love the white cap. Still working out little functions but better for Lucy on my life . Thanks Waterdrop

February 08, 2022

Great idea, really easy to set up. Only thing I would suggest is when calibrating bottle, being able to tell it which drop has been used instead if having to edit every entry...I'd rather calibrate the bottle for each drink once rather than edit the automatic entries multiple times

February 07, 2022

A must have. It keeps track of what you have drunk. It syncs seamlessly with the Waterdrop hydration app. No more having to remember to add drinks to the amount you have drunk. I’ve owned Lucy for about a week and wouldn’t be without her

February 05, 2022

Like it a lot but doesn't sync well

February 03, 2022

Lucy is a great new idea and certainly helps to prompt me to drink more water. I love the way you can clean the water before drinking it too.

February 03, 2022

Requires quite a bit of charging, about every 3 days. Good reminder to drink more water. When using it on glass bottles, the cap looks better with a smaller bottle (400mL) than a bigger one (1L).

January 17, 2024

Generally a good product but it doesn’t always register when you have had a drink from the bottle with the app

June 07, 2023

I'm sure the smart cap is great if you work in an office or have a desk you can set the bottle down flat for the sensors to work...but I drive all day and walk dogs...I bought a 1 LTR bottle that fits in no car drink holders in the UK - so I set the bottle next to me and the cap can never measure because the water never really settles as the car moves or is slightly on its side. Expensive trial for me :( but as I said, I'm sure it would be great for someone who can set the bottle flat after each use.

April 10, 2023

Love the concept, the only down sides are the battery that doesn’t last very long + need to keep the bottle up straight otherwise it leaks

August 03, 2022

Very good and accurate. Had a few issues setting it up but after a day or so it works perfectly and with the app I'm drinking so much more water.

July 18, 2022

I really like it, but the manual is not clear. The cap helps me to drink more. The only problem I have is that it does not measure all the time right. I hope it only depends on the charging level. I will observe it; maybe it is just handling errors by myself

July 18, 2022

Great tool for getting me to track and drink more water. Battery life is pretty good if only using for tracking, it goes down quite fast if using for cleaning water though.

July 15, 2022

Because the LUCY cap links into the MyHydration app it makes logging what you have drunk each day a lot easier, especially during a busy workday. The UV function is interesting, and having LUCY linked with any reminders set on the app is great. Because the cap isn't large it's easy to carry around so you can quickly log your drinks each day.

February 04, 2022

As a reminder it works and as an indicator of how much you are drinking it does the job. It does miss drinks and after it has been inactive for a few hours it takes a while to shift into working again. Calibration is difficult to make happen. I can’t prove that the water cleaning works but I have to assume it does and is great to have. I needed to drink more and it helps me but if you are competitive and want to achieve all of the badges etc then the inaccuracy in its readings may become frustrating. Hopefully future software updates could improve the wake up delay or calibration or readings.

The flashing lights are great at reminding me to drink. It doesn't always seem the most accurate at measuring how much water has been drunk though, it's usually 10-20ml out (eg thinks I've had 580ml despite my bottle being full) but the other day it logged me drinking 450ml out of my 600ml bottle…

September 30, 2023

Love the UV-C cleaning feature and I definitely remember to drink more water, but it doesn't seem to automatically record how much I've drunk very often!

August 08, 2023

I cannot rate it, unfortunately, because the app is not working in the country where my phone is registered - Romania

October 05, 2022

Was fab at 1st but then became inaccurate

July 15, 2022

I’m impressed that it links to the app. I don’t think the light to remind you that it’s time to drink is bright enough as I hardly notice it

February 12, 2022

Very temperamental. Only works sometimes 3rd lucy smart cap replacement. This one might be going back for full refund. We will see.

May 16, 2023

As long as it worked, I was very satisfied - practical, easy-to-use and aesthetically pleasing equipment. Unfortunately, after a few uses it stopped working and I have been trying to figure out what to do with it for several weeks. I had to buy previously used Brita filters for this time, but I admit that it takes too long. I recorded videos and the technicians are still processing my case. For this reason - a great disappointment. I miss using Smart Cap and would like to continue to do so. I will probably have to buy a new one, because it does not look like anyone will help me with the current one.

November 08, 2023

Tried to charge it but would only go up to the second petal. Nothing seemed to work right. For the price, I am disappointed that the cap do not get tested before getting sent.
