The Amazfit Bip is one of the cheapest fitness trackers available. It has been on sale many times before, but today's sale marks the lowest price ever.

Best Buy currently has the Amazfit Bip on sale for $46.99. This is the cheapest smartwatch we have seen and the lowest price ever for the Amazfit Bip.

It would be hard to find another budget fitness tracker with heart rate monitoring, GPS, color display, and smartphone notifications at this price. But the Bip has all of these features, which is why it makes our list of best smartwatches. And if you turn off the smart features, the Bip has a battery life of about 45 days. In our review of the Amazfit Bip, we really liked the soft silicone band, which fits both thick and small wrists. The display is not high resolution, but the transflective technology makes it easy to read even in bright sunlight.

Yes, there is a trade-off: you can see notifications, but you cannot respond to them on the watch. And while you can change the watch face and check the weather, there is no app store, so don't expect Apple Watch-like functionality. At this price, however, it is a great choice for aspiring fitness enthusiasts.
