Stops working. Was working well and all of sudden stopped working on Android. Now, I am trying to set up and not receive a text message to complete the connection. If it is an international app, then e-mail should also be a way to complete registration. What is worst is fitness data for months has been lost. Disappointed. Again had an upgrade today 9/11 and now it is crashing. Will again loose the data until a newer version with fixes is released.

I strongly recommend switching to another smartwatch brand. Most of the watch faces on FastTrack are paid, while many competing brands offer watch faces for free. Even the free watch faces available are very limited and not satisfying. A smartwatch should provide good customization without constantly asking users to pay extra. Because of this, I have decided to switch to another brand and would recommend others consider alternatives that offer better value and free watch face customization.

Hi Yuvrajsinh, we understand your disappointment. To support ongoing development and offer higher-quality designs, some premium watch faces now require a one-time purchase. However, we still maintain a wide selection of free faces. For more feedback, contact us at 1800 266 0123 or customercare@titan.co.in.

I use this app in tandem with the ft reflex watch. I like the watch, but the app is very basic. a. sleep tracking, it's important to see and track resting hr, Min hr. I also think the algorithm may be missing rem sleep b. activity: lots of activity options to choose from. I like that it gives equivalent steps at the bottom of each activity report. for running, a cadence analysis would be great. perhaps the watch can be upgraded to include a metronome to track cadence. vo2 max required
