When my coworker told me aboutthe Water.io Smart Water Bottlethat make certain you ’re drinking enough water , I have intercourse I could n’t be a dependable nominee to test it out . It ’s implausibly unmanageable for me to stay hydrous ; often , I ’d realize at night that I had n’t had any body of water all daytime . Even a evaporation - rush two - month - long kidney disease in the summertime of 2012 could n’t get me to change my habit . I was hoping the Water.io Smart Water Bottle could do that . But it could n’t .

Cons
How it works
You depart by downloading the bottle ’s companion app on your earphone and introduce yourself to it by answering a couple of ready head about your age , sex , height , weight , etc . The app utilizes that intel to store and inform you about your advocate daily water intake .

The bottleful sends you even hydration reminder throughout the day by have its cap hover and light up in a color of your alternative . The cap also embeds duple monitoring sensing element that dog the amount ( down to the ml ) of water you drink throughout the sidereal day . Your figures are update on the app as soon as you ’re done drink in and arrange the bottle down on a flat aerofoil .

you may slant the bottle to verify if you ’re on caterpillar track at any point during the day . The LED anchor ring on the capital will shoot green if you are and orange if you ’re not . To review your progress so far , head to the app . If you successfully play your finish for the twenty-four hours , the crownwork will get off up in rainbow colour as a gratulatory motion .
Where it failed
For some cause , the app used my response to its hydration quiz to set a fairly down in the mouth water inspiration goal for me . Online water intake calculators have always recommended somewhere between 1.6 and 2.6 liters , but the Smart Water Bottle suggested that my total casual hydration amount be 1.3 litre . I manually adjusted the goal on the app and kindle it to 1.6 liters .
During the ten - mean solar day review point , I complied with the bottle admonisher and was hydrous whenever expect , aside from my even need to drink in H2O whenever I genuinely sense athirst . I ’d determine the green / orange on - cart track / off - track status often throughout the Clarence Day and mostly find it on greenish .
After a few days of obediently complying with every hydration reminder and always having the cap light up in green , I was disordered about why my campaign had n’t been lionize with a rainbow yet . When I navigate to the calendar choice on the app to appear at my progress rings for the past week , I learned that I had n’t met my end even once .

This feeding bottle ’s biggest flaw is that it does n’t inform you how far behind on your goal you are . For that data , you have to head to the app , which is not something you ’ll in all likelihood be doing multiple times a solar day , nor is the percentage point of this bottle . There are free hydration - track apps for that .
The only way the bottle keeps you updated on your destination is by flashing green or orange , which translate to being on or off - path . And this specific metric is so lenient that it does n’t profit anyone . It flashed greenish for me on Clarence Shepard Day Jr. when I could n’t contact even half of my total goal . The only metre it would flash orange was when I ’d fall home to the bottleful after a long day of not using it . But I noticed quickly that taking a few sips would make it green again , which was deceiving . It does n’t deserve a dark-green light if I ’ve just started my daily H2O consumption .
It would have been a far better approximation to have the LED ring on the bottleful ’s cap study as a progress tracker , with the perimeter as the total water intake end . The lot would slow replete up as you ’d come closer to fulfill it , just as it work on the app . This would ’ve worked much well in conveying a more precise overview of just about how much more you need to drink for the rest of the day . Coupled with the excessively soft and outright deceptive on - caterpillar tread / off - track metric , it made me highly misinformed about my intake goal .

It ’s shameful , I know , but one day out of the ten years I brush up this feeding bottle , I sire a rainbow . It was so discerning that I would ’ve easily missed it if I had n’t already happened to have the bottle in hand as I refilled it .
Unlike the loud hydration reminders and take attention , the celebratory rainbow show up for an exceedingly brief moment , only when you wobble the bottle to one side , without vibration , and extremely quietly . I was moderately underwhelmed after looking fore to it for days . With a celebration so inconspicuous that it ’d easily go unnoticed , it ’s not very encouraging . Interestingly , I did n’t exactly forgather my finish on even this solar day . I imagine it awards you even when you ’re close .
If you ’re going before with this bottle , remember that it ’s one extra gimmick to add to the ever - grow list of machine that require to be consign . It took an hour to strike 100 % , and it lasted ten days until the crown started flash red to point a down battery . Ten days is a good enough battery life on a twist if it ’s offering sufficient time value , though .

But with magnetised charging on this bottleful , you ’d need its specific proprietary cable . That ’s one extra cable to think about and care for , which instantly set me off looking at how we ’re at last getting closemouthed to bear auniversal charging standard . Also , if you lose the cable , you ’d necessitate to husk out $ 7 to purchase it on the site .
Where it passed
The Water.io Smart Water Bottleis a bottle I ’d buy anyway , ground on its design , even if it did n’t offer any impertinent feature of speech . It features a satiny , robust body and an extremely lightweight build . My review unit included the $ 10 handle ( betray one by one ) that I found somewhat useful .
The fellow traveler app has a slightly janky interface and is prostrate to crash . But if you may get past its low - tone UI , it ’s packed with feature article and wages . It let you manually append any physical activeness you did during the day and adapt your goal based on those . you could manually add hydration outside the bottle , such as chocolate , vino , etc .
There are dozen of badge to help motivate you and a leaderboard to keep the most effective water system drinkers . I was glad than I ’d wish to accept when I obtain my first ( and only ) badge .

Is it worth it?
Water.io ’s Smart Water Bottle desperately want a advance tracker on the bottle itself . Its on - data track / off - rail status updates also want to be far impudent . Throughout my review period , the bottleful just endeavor to get me to hydrate because it was always immature and had a positive status , even when I was highly behind on my goal .
Apart from the very helpful reminders , the desire to see complete procession circles on the in - app calendar , earn badge , and unlock rewards greatly encouraged me to hydrate . Water.io gamifies hydration for you , and it ’s admittedly enjoyable . However , online hydration trackers and apps can do the same without pass $ 70 . The feeding bottle auto - inputs your water intake via the sensors , which is impossible on a hydration app . The Water.io Smart Water Bottle is honorable for traverse hydration than pushing you towards it .
