COLMI vs Amazfit: Which Budget Smartwatch Brand Should You Choose in 2026?

Two names dominate the budget smartwatch conversation in 2026: COLMI and Amazfit. Both brands promise premium features at accessible prices. Both offer AMOLED displays, health tracking, and GPS options well under £100. But they take meaningfully different approaches to the market, and choosing between them depends heavily on what you prioritise in a smartwatch. This is the most comprehensive, honest comparison of COLMI and Amazfit available in 2026.

Brand Overview

Amazfit

Amazfit is a sub-brand of Zepp Health, itself a spinoff of Xiaomi's health technology division. Founded in 2015 and headquartered in China, Amazfit has invested heavily in building a sophisticated software ecosystem, proprietary health algorithms, and brand recognition in the UK and European market. Models like the Bip series, the GTR range, and the T-Rex line have established Amazfit as the go-to recommendation among tech reviewers for budget-to-mid-range smartwatches. The Zepp app and Amazfit's AI health coaching features are among the most refined in the non-premium segment.

COLMI

COLMI is a Chinese wearable brand that has built its UK and European market position primarily through exceptional hardware value. Rather than investing in proprietary health algorithms or a sophisticated app ecosystem, COLMI focuses on delivering the best possible display, sensor, and battery hardware at the lowest possible price. The Da Fit companion app is functional but not exceptional. What COLMI lacks in software depth, it compensates for in hardware generosity — AMOLED displays, GPS, and comprehensive sensor arrays at price points that typically undercut Amazfit by £10 to £25 per comparable model.

Price Comparison

Price is where the COLMI vs Amazfit comparison starts, because the gap is meaningful and consistent:

• Entry AMOLED: COLMI V72 (~£33) vs Amazfit GTS Mini (~£55) — £22 saving with COLMI
• Budget GPS: COLMI P82 (~£50) vs Amazfit Bip 5 (~£70) — £20 saving with COLMI
• Mid-range AMOLED: COLMI i28 Ultra (~£44) vs Amazfit GTR Mini (~£75) — £31 saving with COLMI
• Premium GPS: COLMI V76 GPS (~£62) vs Amazfit T-Rex 3 (~£180) — £118 saving with COLMI

The pattern is consistent: for roughly equivalent hardware features, COLMI is typically 25 to 40% cheaper than the comparable Amazfit model. This difference is real money, not a trivial rounding error, and it shifts the value calculus significantly.

Display Quality

Both brands have moved to AMOLED displays across their mid-to-upper range in 2026, which means the baseline picture quality is similar when comparing equivalent models. AMOLED is AMOLED — true blacks, vivid colours, high contrast — and the visual technology is the same regardless of brand name on the case.

Where differences emerge is in display resolution and size:

• Amazfit's GTR 4 and GTS 4 feature high-resolution AMOLED panels (480×480 pixels) that produce extremely sharp text and detail
• COLMI's i28 Ultra features a 466×466 pixel AMOLED that's very close in sharpness and visually comparable in daily use
• COLMI's P82 offers a 2.13-inch AMOLED display that's physically larger than most equivalent Amazfit models, providing superior readability for those who prioritise screen size

For most users in daily use, the display quality difference between a COLMI and Amazfit AMOLED watch is not practically meaningful. Side by side on a spec sheet, Amazfit's higher-end models show slightly higher pixel density. Side by side in real life, most people would struggle to identify which is more expensive from the display alone.

Winner: Roughly equal for mid-range AMOLED. Amazfit edges ahead at the premium tier in resolution; COLMI offers larger physical displays at equivalent prices.

Health Tracking Features

This is where the comparison becomes more nuanced. At the hardware level — sensors, measurements taken, metrics available — COLMI and Amazfit offer very similar feature sets across comparable models:

• 24/7 heart rate monitoring: both brands
• SpO2 monitoring: both brands
• Sleep stage tracking (light, deep, REM): both brands
• Stress monitoring via HRV: both brands
• Step counting and calorie estimation: both brands
• 100+ sports modes: both brands (mid-range and above)
• GPS (built-in): select models from both brands

Where Amazfit genuinely differentiates is in the quality of its health algorithms and the depth of insights provided through the Zepp app:

• Body Battery / Readiness Score: Amazfit's Zepp app provides a sophisticated readiness and energy score that synthesises sleep, HRV, stress, and activity data into a single daily guidance metric. This is significantly more useful than the raw data displays in COLMI's Da Fit app.
• PAI (Personal Activity Intelligence): Amazfit's PAI score translates your heart rate history into a single weekly health score designed to correlate with long-term cardiovascular health outcomes. It's based on research from the Norwegian University of Science and Technology.
• Menstrual health prediction: Amazfit's cycle tracking uses skin temperature alongside cycle history to predict ovulation windows with greater accuracy than pure calendar methods. COLMI's cycle tracking is calendar-based.
• AI training coach: Higher-end Amazfit models include AI-generated training plan suggestions and post-workout performance feedback. COLMI provides no equivalent.

Winner: Amazfit for algorithm sophistication and depth of health insights. COLMI for hardware feature breadth per pound spent. The gap is most significant at the app and algorithm level, not the sensor level.

GPS Performance

Both brands offer GPS-equipped models, and in terms of raw GPS performance for recreational use, the difference is modest. COLMI's P82 and V76 GPS deliver accurate distance and route tracking for running, cycling, and hiking that is entirely sufficient for the vast majority of recreational athletes.

Amazfit's GPS models (Bip 5, Cheetah series, T-Rex 3) benefit from dual-band GPS capability on higher-end models, which improves accuracy in urban environments and dense tree cover where single-band GPS can struggle. For trail runners or city runners who want the most accurate GPS tracking available, Amazfit's dual-band models have a meaningful advantage. For hikers in open countryside and recreational cyclists, the difference is largely academic.

It's also worth noting that COLMI's P82 offers built-in GPS alongside a 2.13-inch AMOLED display and Bluetooth calling for around £50 — a combination that Amazfit doesn't offer at anywhere near that price point.

Winner: Amazfit for GPS accuracy at the high end (dual-band). COLMI for GPS value — more GPS features per pound spent.

Battery Life

Battery life is consistently a COLMI strength. Comparing equivalent-feature models:

• COLMI P86: Up to 12 days typical use
• Amazfit GTR Mini: Up to 14 days (comparable)
• COLMI P82 (with GPS): 7–10 days standard, 12–15 hours continuous GPS
• Amazfit Bip 5 (with GPS): Up to 10 days standard, up to 9 days with GPS (using less intensive GPS modes)

Battery life is broadly comparable between the two brands at equivalent feature levels, with neither brand having a decisive advantage across the range. Amazfit's higher-end models with GPS economy modes can achieve impressive battery life under specific conditions; COLMI's P86 and P81 deliver outstanding battery life for non-GPS use.

Winner: Broadly equal. Specific advantages vary by model comparison.

App and Software Experience

This is the most significant qualitative difference between the two brands and is where Amazfit earns much of its price premium.

The Zepp app (Amazfit's companion) is one of the best health apps in the non-premium wearable segment. It's well-designed, intuitive, provides rich health insights with clear explanations, and offers genuinely useful daily guidance through the Body Battery and readiness features. Third-party integrations are extensive: Apple Health, Google Fit, Strava, Komoot, and others connect seamlessly. The app receives regular updates and improvements, and the health coaching features are backed by meaningful research.

The Da Fit app (COLMI's companion) is functional and well-organised. It presents your health data clearly, stores it indefinitely, and allows you to configure watch settings and download watch faces. What it doesn't do is interpret your data, provide actionable guidance, or integrate deeply with third-party platforms. It's a data display tool, not a health coaching platform.

For users who will actively engage with health insights and guidance, this difference is significant and arguably justifies Amazfit's price premium. For users who primarily want to see their numbers without in-depth analysis, COLMI's simpler app is entirely adequate.

Winner: Amazfit — decisively. The Zepp app is substantially better than Da Fit for users who want depth of health insight and coaching.

Design and Build Quality

Both brands offer a range of designs from sporty to elegant, and both have improved their build quality substantially in recent years. At equivalent price points, the difference in perceived build quality is minimal — both feel like well-made budget devices with solid cases, comfortable straps, and no obvious quality shortcuts.

Amazfit has historically offered slightly more design variety within each price tier, with dedicated rugged models (T-Rex series), ultra-slim models (GTS 4 Mini), and round-case models (GTR series) providing genuine differentiation. COLMI's designs are primarily rectangular across the range, though the P85's horizontal screen and P86's curved display provide visual distinctiveness.

Winner: Amazfit for design variety. COLMI for hardware quality per pound spent.

Smart Ring Range

COLMI offers a complete smart ring lineup (R02 through R12) that has no equivalent from Amazfit. If you're interested in the smart ring form factor — for sleep tracking, comfort, or discretion reasons — COLMI is the only choice between these two brands. Amazfit does not currently offer a smart ring.

Winner: COLMI (by default — Amazfit has no smart ring).

No-Subscription Policy

Both COLMI's Da Fit and Amazfit's Zepp app provide their core features without a subscription. Neither brand gates your basic health data behind a paywall, which distinguishes both positively from Oura's subscription model. Some of Amazfit's advanced AI coaching features are available as premium add-ons on certain models, but the core health data is freely accessible.

Winner: Tie — both brands provide good no-subscription data access.

Which Brand Should You Choose?

Choose COLMI if:

• Budget is your primary constraint and you want the most hardware for the least money
• You want a smart ring rather than a smartwatch
• You primarily want health data to look at rather than interpreted insights to act on
• You want the largest possible AMOLED display at the lowest price (P82's 2.13-inch)
• You want GPS and calling in one watch under £50 (P82)
• You're buying a smartwatch as a gift and want something that looks premium without a premium price

Choose Amazfit if:

• You want sophisticated health insights and AI coaching alongside hardware tracking
• You want dual-band GPS for maximum accuracy during running or urban activities
• You want deep third-party app integrations with Strava, Komoot, and similar
• You want PAI scoring and scientifically grounded fitness guidance
• You value a polished, feature-rich app experience and are willing to pay the premium for it
• You want a round watch face design (GTR series)

Our Verdict

COLMI and Amazfit are both excellent brands at their respective price points, and both represent genuinely good value compared to Garmin, Samsung, or Apple alternatives. The choice between them comes down to a single key question: do you want better hardware for less money, or better software insights for more money?

For buyers who will actively engage with health coaching features, training guidance, and depth of data interpretation, Amazfit's premium is justified. For buyers who primarily want a well-built, feature-rich smartwatch or smart ring at the lowest possible price, COLMI delivers outstanding value that Amazfit can't match per pound spent.

In our experience, the majority of everyday smartwatch buyers fall into the COLMI camp — they want the data, they want the features, and they want the display quality, but they don't need AI coaching to make use of what a wearable offers. For those buyers, COLMI is the smarter purchase in 2026.
