COLMI vs Fitbit: Which Brand Is Better Value in 2026?
Fitbit is one of the most recognisable names in wearable health tracking, and for good reason — it's been around since 2007 and now sits under Google's ownership with a genuinely capable lineup. COLMI is a newer, budget-focused challenger. So which actually makes more sense for your money in 2026? We compared both ranges honestly, including the parts of Fitbit's model that COLMI doesn't have to deal with.
Fitbit's Current Lineup, Briefly
As of 2026, Fitbit's range centres on a handful of devices: the Fitbit Inspire 3 (a slim, screen-equipped fitness band without built-in GPS), the Fitbit Charge 6 (Fitbit's most complete tracker, with built-in GPS, ECG, and Google Wallet and Maps support), the newer screenless Fitbit Air (an entry-level tracker built around Google's AI-powered Health Coach), and the Fitbit Sense 2 and Versa 4 smartwatches. The older fashion-focused Fitbit Luxe is being phased out, with official support ending in mid-2026. It's a smaller, more focused lineup than it used to be, with Google clearly steering hardware innovation toward the Pixel Watch instead.
The Subscription Question: The Biggest Difference
This is arguably the most important practical difference between the two brands, and it's one that often gets buried in spec-sheet comparisons. Fitbit devices generally come with a free trial of Fitbit Premium (recently rebranded alongside the Google Health app) — typically three to six months depending on the model — after which continuing to access full historical trends, guided programmes, and AI coaching costs around £7.99 a month or roughly £80 a year. Some core stats remain visible without a subscription, but the deeper insights Fitbit markets heavily are gated behind that ongoing cost. COLMI's Da Fit app, by contrast, is entirely free with no subscription tier at all — every feature the hardware supports is available from day one, indefinitely, at no extra cost beyond the initial purchase price.
Price Comparison
| Tier | Fitbit | Price | COLMI Equivalent | Price |
|---|---|---|---|---|
| Entry tracker | Fitbit Inspire 3 | ~£85 (often discounted to £60–75) | COLMI C8 Max / V69 | £32–34 |
| Mid-range GPS | Fitbit Charge 6 | ~£140 (often discounted to £100–120) | COLMI P82 | £50 |
| Dedicated GPS | Fitbit Charge 6 | ~£140 | COLMI V76 GPS | £62 |
| Screenless tracker | Fitbit Air | Entry-level pricing, subscription encouraged | COLMI R02 smart ring | £28 |
Even accounting for regular Fitbit discounting, COLMI's equivalent tier typically costs less than half, before you factor in the ongoing subscription some Fitbit features expect.
Where Fitbit Genuinely Wins
It would be dishonest to pretend COLMI beats Fitbit on every front. The Fitbit Charge 6 includes ECG functionality for heart rhythm checks, which no COLMI device offers, and integrates properly with Google Wallet and Google Maps — genuinely useful if you're already embedded in the Google ecosystem via an Android phone or Pixel device. Fitbit's brand history also means broader third-party accessory support, more established customer service infrastructure, and software that's had over a decade to mature, even if recent user reports point to some inconsistencies in the Charge 6's heart rate and GPS accuracy during outdoor exercise. If ECG, deep Google integration, or brand longevity matter specifically to you, Fitbit has a real edge COLMI doesn't currently compete with.
Where COLMI Genuinely Wins
Price is the obvious one, but it's not the only advantage. COLMI's core lineup — including watches like the P82 and V76 GPS — includes built-in GPS and Bluetooth calling at price points roughly a third of Fitbit's equivalent Charge 6, with no subscription required to access any tracking feature. Battery life is also generally longer on COLMI's basic AMOLED watches (7–12 days) compared to the Charge 6's roughly week-long rating, and COLMI's smart ring range (R02 through R12) gives you a screenless, discreet tracking option Fitbit has only just started exploring with the Air. If your priority is comprehensive tracking without ongoing cost, COLMI's value proposition is difficult for Fitbit to match at any price tier.
Sensor Accuracy: An Honest Comparison
Neither brand should be treated as a medical-grade device, and it's worth being clear about that regardless of price. Fitbit's longer market history means its heart rate and sleep algorithms have had more real-world refinement over the years, though recent user reports around the Charge 6 specifically note some accuracy complaints during outdoor GPS-based exercise. COLMI's sensors are newer to the market and, in our experience, perform comparably for resting metrics like sleep and general heart rate trends, though we wouldn't claim parity with Fitbit for detailed exercise-specific metrics like VO2 max estimation, which Fitbit's more mature software handles more thoroughly.
App Experience Compared
Da Fit is a straightforward, no-frills app: your stats, your history, your watch face library, with no upsells or premium gating. The recently rebranded Google Health app that now powers Fitbit is more polished and includes genuinely useful features like the AI Health Coach and richer historical trend visualisation, but a meaningful portion of that experience sits behind the Premium subscription rather than being included with your purchase. If you want a completely free, unlocked app experience from day one, Da Fit delivers that in a way Fitbit's current model doesn't.
Ecosystem Lock-In
Buying into Fitbit today effectively means buying into Google's ecosystem — devices now require a Google account, and deeper integration (Wallet, Maps, Gemini-powered coaching) assumes you're already using other Google services. COLMI's Da Fit app is platform-agnostic in a more basic sense: it works the same way regardless of whether you're on Android or iOS, without nudging you toward any particular software ecosystem beyond the app itself.
Design and Build Quality
Fitbit's hardware benefits from years of industrial design refinement — the Inspire and Charge lines in particular are genuinely comfortable, well-built pieces of hardware. COLMI's build quality has improved significantly across recent model generations (the AMOLED-equipped V-series and P-series watches in particular), but a fair comparison would note that COLMI's plastics and finishes generally read as more budget-oriented than Fitbit's, which is broadly in line with the price difference between the two brands.
Who Should Choose Fitbit
If you're already deep in the Google ecosystem, want ECG functionality, or specifically value Fitbit's more mature health algorithms and don't mind paying for an ongoing subscription to unlock full features, Fitbit remains a solid choice — particularly the Charge 6 if GPS and payments matter to you.
Who Should Choose COLMI
If you want comprehensive health tracking, GPS, and Bluetooth calling without an ongoing subscription, at roughly a third of Fitbit's price for equivalent features, COLMI is the more straightforwardly good-value option for most buyers. It's also worth considering if you want the option of a smart ring rather than a wrist-worn tracker, since COLMI's ring range is considerably more developed than Fitbit's early screenless offering.
Our Verdict
Neither brand is objectively "better" across the board — they're solving slightly different problems. Fitbit is polished, Google-integrated, and backed by over a decade of software refinement, but increasingly expects an ongoing subscription for its full value proposition. COLMI is newer and its hardware finish reflects the lower price point, but it delivers genuinely comparable core tracking, longer battery life on comparable models, and zero subscription cost. For most UK buyers prioritising value without giving up meaningful functionality, COLMI is the more sensible choice; for buyers already invested in Google's ecosystem or who specifically want ECG, Fitbit remains worth the premium.
The Google Account Requirement
One change that's worth flagging specifically for existing Fitbit owners considering an upgrade: newer Fitbit devices require migrating your account to a Google account if you haven't already, which also means agreeing to Google's broader data and privacy terms rather than Fitbit's original standalone policy. For some buyers this is a non-issue since they're already using Google services daily; for others who specifically chose Fitbit in the past to avoid deeper Google integration, it's a meaningful shift in what you're signing up for. COLMI's Da Fit app requires only its own account, with no obligation to link into a wider tech ecosystem.
Long-Term Software Support
Fitbit has a mixed recent record on long-term support — several older devices, including the Fitbit Sense, Versa 2, Versa 3, and Inspire 2, have already had their support windows closed, meaning devices that still work physically lose access to app updates and, in some cases, historical data features. This is worth knowing if you're buying a Fitbit expecting years of continued software development, since Google has been actively narrowing which legacy devices it continues to support as it consolidates the lineup. COLMI's range is newer overall, so long-term support patterns are less established, but the absence of subscription-gated features at least means a COLMI watch that stops receiving updates doesn't lose access to functionality you're already paying monthly for.
Warranty and Customer Support
Fitbit, backed by Google, offers standard manufacturer warranty terms and an established support infrastructure with phone, chat, and community forum options — a genuine advantage of buying into a large, well-resourced brand. COLMI, as a smaller and newer company, offers UK-based support through retailers like ourselves, with free UK delivery and warranty support handled directly rather than through a global support operation. For buyers who value the reassurance of a large company's support infrastructure, that's a legitimate point in Fitbit's favour, even if day-to-day product reliability between the two brands is broadly comparable.
Matching the Brand to What You Actually Use a Wearable For
It's worth stepping back from spec sheets and subscription costs to ask a simpler question: what do you actually use a wearable for, day to day? If it's mostly glancing at steps, sleep, and heart rate trends without digging into detailed programme-based coaching, the subscription gap between the two brands barely matters, and COLMI's lower price becomes the deciding factor. If you're the kind of person who genuinely uses guided workout programmes, wants an AI coach adjusting your training plan, and is already paying for other Google subscriptions, Fitbit's ecosystem starts to look more justified relative to its cost.
Buying Decision by Budget
Under £50, COLMI has the category essentially to itself for anyone wanting AMOLED, GPS, or calling — Fitbit doesn't have a comparable option at that price point once you factor in typical Charge 6 pricing. Between £50 and £100, it's a genuine choice: COLMI's most advanced watches sit here, and so does the occasionally-discounted Fitbit Charge 6, at which point ECG and Google integration become real deciding factors rather than theoretical ones. Above £100, you're generally paying full price for Fitbit's Charge 6 or stepping into Sense 2 or Versa 4 territory, at which point you're no longer really comparing against COLMI's core range at all.
Frequently Asked Questions
Do I need a subscription to use a COLMI watch fully?
No. The Da Fit app is entirely free, with every tracking feature the hardware supports available at no additional cost, indefinitely.
Does Fitbit require a subscription to work at all?
No, basic tracking works without Premium, but deeper historical insights, guided programmes, and AI coaching features are gated behind the subscription, which costs roughly £7.99 a month or £80 a year after any included free trial period ends.
Is COLMI as accurate as Fitbit for heart rate tracking?
For resting and general trend data, the two are broadly comparable in our experience. For detailed exercise metrics like VO2 max, Fitbit's more mature software currently offers a more developed feature set.
Can I use Google Wallet or Google Maps with a COLMI watch?
No, COLMI watches don't offer contactless payment or on-watch mapping integration. If those specific features matter to you, the Fitbit Charge 6 is the better choice.
Does COLMI make anything comparable to the Fitbit Air?
COLMI's smart ring range (R02 through R12) offers a similar screenless, discreet tracking experience, generally at a lower price point and without any subscription requirement for full feature access.
Will my old Fitbit still work if I don't upgrade?
Physically, yes, but Google has been progressively closing software support for older models, which can mean losing access to app updates and some historical data features over time — worth checking your specific model's current support status before assuming indefinite functionality.
