Bottom Line

We purchased the Letsfit Fitness Tracker so our expert reviewer could thoroughly test and assess it. Keep reading for our full product review.

The Letsfit Fitness Tracker takes fitness watches back to the basics. It tracks steps, sleep, heart rate, and exercise, and it notifies you of calls and messages. It also comes in at an incredibly low price. But does the cost of the Letsfit Fitness Tracker compromise its quality? I tested it to find out.

Setup Process: Simple, after a charge

The Letsfit Fitness Tracker didn’t immediately turn on when I removed it from the package, and various tries never lit up the screen. After I plugged it in to charge, the screen illuminated and I saw the battery was already a quarter full. After an hour, it was fully charged—you’ll know it’s ready when the red light dims.

I had to dig into the user manual to find the app the device pairs with. To download it, either scan the QR code in the manual or search VeryFitPro in your app store. I wasn't sure it was the correct one at first, as the branding between the app and the fitness tracker is very different (one has bright green colors, the other bright orange).

Once downloaded, pairing the device was extremely simple. I had to make sure the phone’s Bluetooth was on and then tap the fitness tracker to wake it. Within seconds, they were connected, and I filled out my profile with physical details and my fitness goals. You can set a step, sleep, and weight goal. 

If you have any issues during setup, the included user guide is fairly comprehensive and covers troubleshooting issues and usage questions.

Compatibility: One app only

In order to pair with your phone, you’ll need iOS 7.1 or later, or Android 4.4 or later. It’s not suggested that you use the device with computers or tablets like iPads.

I wore another fitness tracker along with it to compare the data and found the Letsfit tracked almost 1,000 fewer steps.

The Letsfit Fitness Tracker pairs with the VeryFitPro app to chart your data. Unfortunately, it’s rated a mere three stars in the Apple App Store, and it shows (more on that later). Unfortunately, there doesn’t seem to be a way to connect to third-party apps so users will have to settle.

Design: A Fitbit dupe

Initially, I was surprised at how much the Letsfit resembled my Fitbit, with the same comfortable silicone strap. I do wish it had a more breathable, perforated sports band option to make it less prone to sweat buildup during exercise. The screen is similar to Fitbit’s, too, though the Letsfit is controlled via only a small area below the screen. Using the screen is easy, and the Letsfit responds quickly to my touch.

You’ll spend a lot of time in the VeryFitPro app viewing data, so the design here is important, too. While it is initially visually appealing and easy to use, little discrepancies in graphs and text bothered me. My biggest problem is that the app appears to be translated from another language. That wouldn’t be a problem but for the odd grammar and word choices that can make understanding it difficult. However, I do applaud the app for being simple to understand and navigate and always syncing quickly with the fitness tracker—but it may be a little bit too simple, as we’ll explain later.

Step Count: Doesn’t count all steps

Since the Letsfit Fitness Tracker easily passes for the Fitbit, I was looking forward to an affordable alternative that does many of the same things. But after a few hours of wear, I already encountered an issue. I had clocked only 40 steps—a number I knew was way below my actual step count. Because of this concern, I wore another fitness tracker along with it to compare the data and found the Letsfit tracked almost 1,000 fewer steps. 

Activity Tracker: Multiple modes

The tracker comes loaded with three activity modes: walking, running, and biking. Within the app, you can add others like yoga, “fitness” and even badminton, though you may only have three modes on the watch at a time. Starting an exercise is easy: Just tap through the watch screens until you find the activity you’re looking for and press and hold to select. 

When the data is inaccurate and the experience less than great, even $30 is too much.

I like that the watch tells me my workout progress with data like steps, heart rate, and calories burned, as well as the summary of the exercise after the workout is complete. Unlike other aspects of the watch, though, my activity data didn’t sync to the app quickly, and once it did the information wasn’t as thorough as I would have liked.

Heart Rate Monitoring: Inaccurate

The Letsfit Fitness Tracker tracks heart rate throughout the day and during exercise, and while you can only view your current heart rate on the watch, you can view your resting heart rate, max, and average HR within the app. It measures using optical sensor technology, which uses an LED light to sense blood volume changes and detect heart rate.

Unfortunately, the data doesn’t seem entirely accurate. While standing still, I watched my heart rate rise from 70 and count up to 128 within seconds. I was also wearing another heart rate monitor, which stayed at a cool 68 the entire time. This happened multiple times when I checked on my heart rate, which leads me to believe that the heart rate monitor of the Letsfit Fitness Tracker cannot be trusted. 

Sleep Tracking: Acceptable, but erroneous 

Letsfit automatically knows when you fall asleep and then begins tracking your sleep stages and time asleep, all of which can be viewed in the app the next morning. In general, I felt it gave me a good overall summary of my sleep, with correct wake-up times. However, I found that it didn’t track the extra half an hour snooze I took after the alarm went off.

Battery: Rechargeable via USB

The Letsfit charges via USB, which is conveniently built into the device. You need to remove the bands in order to charge, and then you can put the tracker directly into a USB port. I found the process of removing the bands mildly annoying, but I also appreciated that I didn't need to add yet another charging cord to my collection. 

Be sure that the battery symbol comes on the screen when you plug it in. I found that I plugged it in upside down at first and didn't realize that it wasn't charging.

The battery is supposed to last five to 10 days, and I feel this is accurate. After wearing on and off for more than a week, the battery was still almost half full, so I think most users will get plenty of wear time before needing to recharge it.

Waterproofing: Fine in the rain, but not the pool

While it’s water-resistant, this fitness tracker is not waterproof. Don’t worry if you get caught out in the rain on a run, soak it with sweat after a hard workout, or even forget about taking it off before you wash your hands. But you should take it off before immersing it, like before swimming or showering.

Price: Low, but still not worth it

This fitness tracker is one of the most affordable on the market, going for around $30. Similar name brand options go for at least double and then some. When it comes down to it, though, the low price is due to a cheaply made product. When the data is inaccurate and the experience less than great, even $30 is too much.

Letsfit Fitness Tracker vs. Fitbit Inspire HR

The Fitbit Inspire HR
is a comparable product to the Letsfit Fitness Tracker. For the most part, they do all the same things, like heart, step, and sleep tracking, as well as phone notifications. The Fitbit comes in at $99 though, a full $60 over Letsfit. The price increase does come with extra advantages, like a fully developed app that lets you track calories eaten and burned and menstrual cycles, as well as the ability to connect with friends and family. The biggest benefit, however, is that Fitbit is known to be more reliable, whereas I’ve found the Letsfit is not.

Final Verdict

Invest in a better product.

Sure it’s cheap, but I found that the Letsfit Fitness Tracker is inexpensive for a reason; I just didn’t trust the data, especially with all the inconsistencies in heart rate and steps. I think it’s worth it to spend more on another product that you can actually trust with your fitness goals.
