First reaction is that S7 appears slightly faster. SCREEN is comparable to old S5 but looks brighter. Second, the Tozo customer support is first class equalling that of much more expensive watches. Apps also similar but adding a few new but not used yet. Big change is a new band-silicone but no pins. It now uses new click-in band technology like more expensive garmin and apple which is very easy and quick to connect. Drawback is that my older S5 extra bands I bought don't fit. Another plus, the TozoHealth is getting much more attention with several updates in past month. My S5 did not have any updates for past year. Overall, the S7 is a small upgrade over S5 but with more stable software. I would highly recommend the watch, it is a premium pick in the very competitive budget friendly market.

I really wanted to like the tozo s7. I have bought tozo watches for years now. However, this one is not as accurate as others. I am currently using both the old and new to compare each and doing a manual check throughout the day. The new one is not picking up my heart rate accurately. I have an irregular heartbeat. I can feel the spikes and drastic drops. The new watch doesn’t pick it up at all. Whereas, the old one does. This effects the calorie burn and the hrv calculations.As for the apps tozo uses, It’s frustrating, because of the connecting and data display issues. The old watch uses a different app than the new one. Both apps are having the same types of issues. I shouldn’t have to close the app or restart the device every day to get it to reconnect. Even then there is no guarantee it will work. I bought the watch to track my heart rate. Not being able to look at the full data or fighting to get it is frustrating to say the least.

Ordered the S3 from Tozo, downloaded the Tozo Health app and am very happy so far with user experience and user interface. Very nice quality and functions. Only drawbacks, gps doesn't seem to work (no routes are saved), and when wearing a shirt above it while running screen is turning on and slides from frame to frame by shirt thinking it is being swiped on. Watchfaces are nice but wish to save more instead of just one. Continue updating the app and keep these feedbacks in mind. It is close to be a very very perfect smartwatch.Questions, reach out to me any time.

It has amazing qualities. One of the amazing qualities is that you can save peoples numbers in the watch. You could also track the steps and all of the health alternatives like how much your heart beating . How many miles you’ve walked and how many calories you’ve burned there is goals like 5K and 10k for it, you have to buy it.
