If you are looking for an affordable way to track your daily steps and activity, or want to upgrade your existing fitness tracker, now is a good time, as every current Fitbit is currently on sale on Amazon.

The Fitbit Inspire 3, Fitbit Charge 6, Fitbit Versa 4 and Fitbit Sense 2 are the latest trackers and smartwatches in Google’s Fitbit line up, and with a range of discounted prices there is one to suit every budget.

I’ve tried and tested each and every one of these devices, and have found they all have value, even at the least pricey end of the scale.

You can pick up the Fitbit Inspire 3 for just £58.99. It’s a very slim and lightweight tracker with a small colour screen. Wear it 24/7 – and you can as it’s waterproof, so it’ll survive the shower – and it’ll track your steps, distance, calories burned, sleep and heart rate to paint a picture of your daily activity.

It also has the best battery life of any Fitbit, rated for up to 10 days of use before you need to plug it in again. On the listing page it is labelled as “Deal selling fast”, showing Amazon shoppers agree this is a great deal.

I like that it’s the only Fitbit with a traditional watch strap, rather than the button and tuck loop on the other three models. However, it’s also the only Fitbit that lacks built-in GPS, so if you want to track your run routes you’ll have to take your phone with you for connected GPS.

If you want GPS and a few more features, the Fitbit Charge 6 is just £98.99, a solid saving on its £139.99 RRP. This still-slim tracker has a larger, better screen than the Inspire 3 and also has Google Wallet support, so you can add your debit or credit card to your wrist for contactless payments.

Google, which owns Fitbit, says you can get up to seven days of battery life on the Charge 6. If you use GPS frequently, expect it to be a little less. But add in blood oxygen level monitoring and an ongoing stress score, and it’s a very accomplished tracker for less than £100.

The Fitbit Versa 4 is on sale for £129.99, down from its RRP of £179.99. While it is marketed as a smartwatch, temper your expectations slightly – but not in a bad way. The Versa 45 is basically a fitness tracker in functionality, but in the form of a watch. That means a larger, better AMOLED screen, so you can see more data and also better read incoming notifications from your iPhone or Android phone.

But unlike the Apple Watch or Google Pixel Watch, you can’t get third party apps on the Versa 4. It still has built-in GPS, up to six days battery life and all the features of the Charge 6, but in a watch-like design.

If you want to go for the top of the line, the Fitbit Sense 2 is discounted to £159.99, but it’s usually £219.99. That’s a big saving on the most advanced Fitbit yet, which adds in real-time stress tracking based on your skin temperature. This prompts you to log why your mood may have just changed, and then the Fitbit app gives you feedback on how to manage stress.

This clever device also has ECG tracking for detecting unsteady heart rhythms that could hint at an underlying condition. The design is similar to the Versa 4, but if you want these extra perks, it’s the Fitbit to get
