It provides a whole lot of options, together with SpO2 monitoring and a few attention-grabbing additions like Bluetooth calling, so it would nonetheless suffice for all of the capabilities you want. However, after utilizing it for a number of weeks, I found that it’s removed from good. Considering that it’s priced at Rs. 3,999 in India, is it adequate to cater to these in search of a traditional-looking good gadget with an enormous show? Read on to seek out out.

Zebronics ZEB-FIT4220CH worth in India

A fast look on the ZEB-FIT4220CH shouldn’t be sufficient to inform that it is a smartwatch. It appears like an everyday chronograph watch with two buttons on the precise facet. Minutes are marked on the show glass, which sits inside a round bezel. The 47mm case is fabricated from steel and can really feel about proper for many who are used to chunkier watches. This additionally makes it a bit heavy at 60g. The again is fabricated from plastic and is held in place by 4 flush Phillips-head screws. Apart from the same old array of sensors on the case again, there are additionally two flat contact factors for the bundled magnetic charging cable.

The watch has a spherical LCD show which measures 1.3 inches throughout. There’s flat glass on prime, which is effectively protected by the marginally raised steel bezel surrounding it.

The silicon materials makes this gadget simple to put on by the day and I didn’t discover it uncomfortable to maintain it on by the night time both. The strap has a regular pin buckle, making it simple to placed on and take off, and it by no means got here undone throughout the assessment interval.

The Zebronics ZEB-FIT4220CH, in contrast to the Redmi Watch, is able to SpO2 monitoring, which is beneficial throughout the present pandemic state of affairs. The smartwatch has a 220mAh battery which Zebronics claims is able to 10 days of standby time.

Zebronics ZEB-FIT4220CH software program

While the match and end are spot on given the ZEB-FIT4220CH’s worth, the software program fell a bit quick, in my expertise. This is in distinction to its prime competitor, the Redmi Watch, which provides a better-looking interface way more by way of software program customisation.

The watch can retailer as much as 5 days’ price of health knowledge, however works finest when paired with an iOS or Android gadget working the Zeb-Fit 20 Series app. This app exhibits all of the health knowledge and can also be wanted to replace the firmware of the smartwatch. It even exhibits the watch’s battery standing (supplied it is not charging), and allows you to customise and arrange notifications, time codecs, DND mode, climate data, gadget location, menstrual cycle monitoring, and extra. Like each different smartwatch app, this one additionally shows your health knowledge, and it is all properly laid out together with useful notes that can assist you perceive it, which I actually preferred.

It would have been nice if Zebronics had a cloud knowledge backup resolution for well being knowledge. I examined this gadget with an iPhone 11, and whereas I used to be initially upset that it didn’t begin backing up my knowledge anyplace, a number of days into the testing interval, deep within the settings (below the Me tab) I found that it might hook up with the iOS Health App when you give it entry. This will synchronise knowledge, which may then keep inside iCloud.

Back to the smartwatch, the customized OS has a Theatre mode that dims the show and turns off vibrations, which can also be helpful at bedtime. The watch can retailer 5 faces, and you have to to open the app to download extra. One of them (Dial 4) may be customised with a photograph out of your smartphone’s gallery. You can change the textual content color and placement, and add as much as two customisable problems from an inventory of preselected apps.

The built-in and downloadable watch faces present a whole lot of knowledge, however they actually just do that. You can not faucet on these problems to open the respective apps and see extra knowledge. A lot of options and a easy UI means you may have to swipe round lots. It takes six left swipes to get to the SpO2 app from the primary watch face. You can alternatively proper swipe to indicate a vertical record of apps, the place you will need to scroll down to seek out the SpO2 app, after which faucet once more to open it… and faucet as soon as once more to take a studying.

The ZEB-FIT4220CH’s software program has transitions and animations while you swipe round and so they had been all easy with none stuttering or lag. You can test notifications from all of your smartphone’s apps, however you can not reply to them.

During the assessment interval I often saved the show brightness on the third of 5 ranges, which appeared greater than sufficient when utilizing the watch indoors. However, below vivid daylight you’ll have to max it out for snug viewing. The LCD has good viewing angles however you have to to show up the brightness manually from the pull-down management panel. This is the place you may additionally discover different toggles and indicators for issues like vibration, the climate, Bluetooth standing, and the battery degree. The 1.3-inch show has a low decision and it is easy to identify jagged edges on textual content and icons all through the UI.

This smartwatch does help Bluetooth calling. You have to pair the watch individually together with your smartphone over Bluetooth, because it doesn’t use the identical connection for calls because it does for knowledge synching. Once paired, the smartwatch permits you to test lately positioned calls, use a dial pad, and name your favorite contacts.

Bluetooth calling works, however is generally a gimmick because of the low speaker quantity


While calling works (supplied the watch is inside vary of the smartphone), the speaker sounded too muffled, making it laborious to know what the caller was saying. Likewise, the mic on the watch doesn’t choose up voices effectively, so I needed to maintain the watch as much as my face to make sure that the individual on the opposite finish might hear me clearly. This means that Bluetooth calling is extra of a gimmick, regardless that it’s useful.

One odd facet impact of the way in which Bluetooth calling has been carried out is that all telephone audio was usually routed to the watch’s speaker. I needed to maintain disconnecting the watch’s Bluetooth calling hyperlink to my telephone after I used to be executed with a name to forestall this from occurring.

The ZEB-FIT4220CH’s coronary heart charge and SpO2 readings had been correct when in comparison with these of a regular pulse oximeter. The blood strain readings had been much less constant and various drastically between exams taken simply minutes aside. These had been additionally very totally different from the numbers I acquired utilizing a physician’s blood strain gauge. Sleep monitoring was correct by way of patterns, however the watch usually acquired the time I really fell asleep improper, that too by giant margins of 2-3 hours. I might not depend on this sleep monitoring knowledge.

The watch provides very primary health monitoring with seven sports activities modes: strolling, working, skipping, soccer, biking, badminton, and basketball. There are not any finer-grained alternatives for variations or extra particular workout routines. If you need to select between indoor biking on an train bike versus an precise bicycle, or working outdoor versus on a treadmill, you will not discover that right here. I attempted the strolling  mode and counted to 1,000 steps manually. The watch registered 981, which is pretty correct given that my path was uneven.

With a 220mAh battery, the Zebronics ZEB-FIT4220CH simply lasted about 6-7 days on a single cost, dropping by about 10-15 p.c per day on common. This is with the show’s brightness set degree 3 more often than not and 5 when outdoor. All notifications had been enabled, well being monitoring options (like coronary heart charge and sleep monitoring) had been additionally switched on, and I tracked a number of train actions on alternate days. Using the Bluetooth calling characteristic regularly does drain the battery rapidly, and brings the standby time you may count on right down to about 3-4 days.

The magnetic charging connector disconnects a bit too simply


Battery life was on par with expectations, however charging is troublesome. The ZEB-FIT4220CH took round 2 hours, 20 minutes to cost totally, which is similar time as most different smartwatches on this worth phase. The bundled cable has a Type-A USB plug at one finish and a magnetic connector on the different finish, which must be rigorously positioned in place on the charging contacts. There isn’t any inset or cutout to assist align the connector, so there have been a number of cases when the gadget acquired disconnected, if the was positioned on its again with the charging cable beneath it. The most secure method to cost it was by inserting the smartwatch with the show going through down.

While the smartwatch is charging, there is no method to entry something on it, until you disconnect the  cable. Pressing the pusher to get up the show solely exhibits a “charging” message with no particulars concerning the standing of the battery. The identical goes for the cellular app, which additionally merely exhibits a charging signal over the battery indicator, with no method to understand how for much longer it is going to take.


After utilizing the Zebronics ZEB-FIT4220CH for about two weeks, it is easy to conclude that it is extra a sensible band with an enormous show than a smartwatch. This is principally due to its very primary UI, restricted health monitoring capabilities, low-resolution show, and lack of primary options equivalent to an ambient gentle sensor.

The Zebronics ZEB-FIT4220CH has numerous options, however not all of them work as anticipated. There’s SpO2 monitoring, Bluetooth calling, and a premium steel physique with interchangeable straps. Plus, this gadget appears and seems like an everyday timepiece. Sleep and blood strain monitoring weren’t dependable, so you must maintain this in thoughts for those who plan to make use of these options.

At a barely increased asking worth (Rs. 3,999), Xiaomi’s Redmi Watch (Review) will get much more issues proper, however does not look very like a standard watch. The customized OS works significantly better, with numerous watch faces and train modes, and it might probably additionally face up to 5 ATM of strain below water. It’s even lighter at 30g. The Redmi Watch additionally has a greater charging cradle, GPS monitoring, and an app that backs your knowledge to the cloud.
