URGENT BUG REPORT

I am using the Fastrack Watch 3.0, and the watch was working perfectly fine with the Fastrack Smart World app before the latest iPhone app update. However, immediately after updating the app, I started experiencing serious syncing issues.

The step count syncs successfully within 30 seconds, but the sleep data never syncs. The app continuously displays the message “Data is syncing, please wait,” even when the watch is properly connected to the iPhone.

The problem also occurs when I navigate to Devices → Settings (gear icon in the top-right corner). The same syncing message appears, and even after waiting 4–5 minutes, nothing happens. Additionally, I cannot access or change watch faces. Tapping “Explore Now” displays the same error.

I have already tried all possible troubleshooting steps:

* Reset the watch.
* Deleted my account and set it up again as a fresh account.
* Uninstalled and reinstalled the app.
* Reconnected the watch to the iPhone.

Unfortunately, none of these steps resolved the issue. Step count syncing works, but sleep data and watch face features remain inaccessible.

This issue clearly appears to be related to a bug introduced in the latest Fastrack Smart World app update for iOS.

I request the development team to investigate this issue and release a fix as soon as possible. The watch’s features were working perfectly before the update, and this software update has significantly affected the overall user experience.

Please treat this as a priority bug report and resolve it in the next update. I hope the technical team takes this feedback seriously.

Good Hardware, but Software needs alot of improvement!

The watch has good potential, but there are way too many software bugs that need to be fixed.

1. AOD scheduling is buggy: I set AOD from 8 AM to 10 PM, but after 10 PM it doesn’t turn off automatically. I have to press the button first, and then it switches off. The same issue happens when AOD is supposed to turn on in the morning.

2. Syncing is very slow and inaccurate: It takes a long time to sync with the app, and even after waiting 20+ seconds, the data can still be incorrect. I did around 1 hour of cardio using 3 different sports modes, and the watch recorded all 3 activities, but the app only showed 1. Steps and calorie data also don’t always match between the watch and the app. I’ve tried syncing multiple times and even unpaired and paired the watch again, but the issue still hasn’t been fixed.

3. Random glitches: Sometimes raise-to-wake and the touchscreen stop responding. I have to press the side button, after which everything starts working normally again.

4. Sleep tracking is extremely inaccurate: I slept for around 7 hours, but the watch recorded only around 3.2 hours.

5. UI needs a redesign: The interface feels outdated, and some animations are laggy. Even rotating the crown on the home screen sometimes causes noticeable lag.

6. Call-related bug: If I receive a call and answer it using my AirPods, the watch interface sometimes hangs/freezes.

7. More watch faces needed: Please add more watch faces and especially more AOD options.

8. The location the watch shows in the weather app is far from my actual location

Overall, the hardware is good, but the software experience needs a LOT of improvement. Most of these issues seem like they could be fixed through software updates. Hopefully future updates improve the syncing, tracking accuracy, UI, responsiveness, and overall stability of the watch.

Can’t use the app

I can’t get the OTP sms when using my American phone number. The same error message of the OTP limit exceeded always shows up. I am unable to use the app or connect it to the watch because of this issue.

Unstable App – Automatically Exits While Using

I am extremely disappointed with the performance of the Fastrack Smart World app on my iPhone. The app constantly glitches and automatically exits while I’m using it, which makes it completely unreliable and frustrating.

I expected much better from a brand like Fastrack, but this kind of instability seriously affects the user experience. An app that cannot even stay open properly fails its basic purpose. It disrupts usage and wastes time, especially when trying to access important features.

I request your technical team to urgently look into this issue and release a proper fix. Until then, I cannot recommend this app to anyone. Please take this feedback seriously and improve the app’s performance and stability as soon as possible.

Horrible

Does not sync with Apple health. I lost my movement and step counting streak from years because this watch says it syncs with Apple health but it doesn’t. The customer support is worse, been messaging them and have not heard back in the last 2 weeks. Such a waste of money.
