Search "Fitbit Charge 6 alternative" and most results compare it to the £139.99 RRP. That makes almost anything look cheap by comparison. But the Charge 6 regularly sells for £79 to £90 at the best current UK deals, and it rarely sits near its RRP for long. A fair alternative has to hold up against that real price, not the number printed on the box. Otherwise you're just comparing a cheap product against an artificially inflated one, and calling it a win either way.
Why people look for a Fitbit alternative
Three things send people looking. The price still feels steep even on sale. Some people prefer a different app, like Samsung Health or Google Fit, over Fitbit's own. Others just want a second tracker for the household without paying full Fitbit price twice. All three of these come down to price and trust in the brand, not a random cheap band with no real name behind it.
The closest real alternative
Samsung Galaxy Fit3: £85.57 (was £89.54)

A 1.6-inch AMOLED touchscreen band with heart-rate and sleep tracking, made by a brand you'd actually recognise. At around £85.57, it sits right in the same bracket as Fitbit's real street price of £79 to £90, not the RRP most "alternative" articles compare against. So the case for it isn't that it's dramatically cheaper. It's that you get comparable everyday tracking, better water resistance, and longer battery life for a similar or slightly lower price, without paying the inflated RRP. We checked that against Fitbit's actual current UK deals, so it's a claim you can verify yourself.
Battery life: Up to 13 days with the always-on screen turned off, or about 3.5 days with the screen left on. That's genuinely good, though it's closer to the Charge 6's own battery life than a dramatic leap ahead of it.
Water resistance: Rated 5ATM and IP68. It's built for swimming, rain, and washing your hands, and it's tested to survive 30 minutes at 1.5 metres deep. It isn't built for diving or a pressure washer.
iPhone compatibility, honestly: Most "alternative" roundups skip this detail. The Fit3 is made for Android and works best paired with a Samsung phone. It will connect to an iPhone running iOS 12 or later, but Samsung says plainly that you won't get every feature that way. If you're on an iPhone and want everything working properly, that's the one honest reason to stick with Fitbit's own app instead.
What you lose versus the Charge 6, if you're on Android, is Fitbit's coaching features and its wider app ecosystem, assuming you're already using it. If you're not already a Fitbit user, that's barely a loss at all.
Pros:
- Priced in line with Fitbit's real sale price, not its inflated RRP
- Long battery life, up to 13 days
- Real water resistance for swimming and rain
- A brand you'd actually recognise
Cons:
- Reduced feature set on iPhone
- Fitbit still wins on coaching tools and app ecosystem
Verdict: A genuine alternative that matches Fitbit's real sale price from a recognisable brand, as long as you're on Android or don't mind losing a few features on iPhone.
If price is the only thing that matters
Entity AERO Smartwatch: £42.34 (was £50.99)

Roughly half the price of the Galaxy Fit3. This is a genuinely basic touchscreen smartwatch, not a real Fitbit substitute, and we won't pretend it matches the Charge 6 on tracking accuracy or app support. It's on this list because "cheapest smartwatch that actually works" is its own valid search, separate from "closest thing to a Fitbit".
Verdict: Buy this if budget is the only requirement. Buy the Galaxy Fit3 if you want something genuinely closer to a Fitbit replacement.

Frequently asked
Is the Galaxy Fit3 as accurate as a Fitbit? Samsung's sensors are well regarded for heart-rate and sleep tracking, but Fitbit has more history building coaching features on top of that raw data. For basic step, heart-rate, and sleep tracking, both do the job well.
Does either work with an iPhone? The Charge 6 does, fully, through Fitbit's own app. The Fit3 connects but loses some features on iPhone, so we wouldn't recommend it as an iPhone-first purchase.
Is a fitness band the same thing as a smartwatch? Not quite. Both trackers here are bands built for fitness tracking with basic notifications, not full smartwatches that run apps, like a Galaxy Watch or Apple Watch. If you want app support and calls from your wrist, that's a different product category entirely.
How long do fitness bands like these usually last before needing a replacement? With normal daily wear and charging, most bands in this price range hold up well for two to three years before battery life noticeably declines. That's worth factoring into the price comparison, since a cheaper band that needs replacing sooner isn't automatically the better deal.
How we priced this
Every price we quote for our own picks is read from the retailer as the page loads. It is today's number, not the one that was true while this was drafted.
For the Fitbit Charge 6 we used its real UK selling price, not the RRP. Comparing a live price against a list price nobody pays would overstate the saving. Some of these are cheap enough to raise questions about what you give up. Those trade-offs are named above rather than left to the low price to explain.
Nobody here has worn these side by side for a month, and it would be dishonest to write as though we had. Heart-rate accuracy and battery claims need proper measurement, which dedicated review sites do. What we can report is what each costs and what the specification includes.
The bottom line
Most "Fitbit Charge 6 alternative" articles compare against a price nobody actually pays. Checked against Fitbit's real UK sale price, the Galaxy Fit3 holds its own, with a real brand behind it, genuine water resistance, and long battery life. Just go in knowing its iPhone limits beforehand.
