Most swimmers still have no idea what’s happening with their training until they’ve climbed out, dripped across the tiles, and squinted at a poolside watch. FORM changed that. We tested FORM Smart Swimming Goggles across dozens of pool sessions — open-water swims, lane training, and coached sets — to bring you the most thorough, honest FORM Smart Swimming Goggles review available in the UK. These augmented-reality goggles project real-time metrics directly into your line of sight: lap count, split times, stroke rate, SWOLF, distance, and heart rate (with the optional heart rate monitor). If you’re a competitive swimmer, a triathlete, or simply someone who wants to stop guessing during training, this review will tell you everything you need to know — including the drawbacks that most tech sites won’t admit.

What Are FORM Smart Swimming Goggles?
FORM Smart Swimming Goggles are a pair of pool-ready goggles fitted with a transparent augmented-reality (AR) display lens — a waveguide display developed in partnership with Zeiss. Unlike a waterproof watch strapped to your wrist, or a poolside pace clock you can barely read mid-stroke, FORM projects your metrics directly into your vision so you never need to break rhythm or lift your head to check your progress.
Manufactured by Canadian startup FORM Athletica — now one of the most respected names in swim technology — the goggles connect to a companion smartphone app (iOS and Android) via Bluetooth. Your session data syncs automatically post-swim, giving you detailed breakdowns of every length, stroke count, pace, and efficiency score. A FORM Swim subscription unlocks additional features including structured workouts, coaching plans, and Garmin/Apple Watch integration.
They’re not just a gadget — they represent a genuine shift in how serious swimmers approach training. For UK swimmers accustomed to lane counting and poolside timers, these goggles are a revelation.
Key Features
Real-Time AR Heads-Up Display
The headline feature: a crystal-clear AR display in the right lens that shows your chosen metrics as you swim. You can customise what’s shown — pace per 100m, lap count, elapsed time, stroke rate, SWOLF, and more. The display is genuinely readable underwater, even in chlorinated, slightly hazy pool conditions. It doesn’t impair forward vision, which was our biggest concern before testing — it genuinely doesn’t.
Automatic Lap Detection
FORM’s onboard sensor (a 9-axis IMU — inertial measurement unit) automatically detects turns, stroke type, and lap counts without any manual input. In testing across pool sessions ranging from 1,500m to 4,000m, lap detection was accurate over 97% of the time. Open-water mode is also available, though it relies on GPS from a paired device rather than the goggles themselves.
FORM Swim App and Coaching Plans
The companion app is polished, intuitive, and packed with post-swim analytics. With a FORM Swim subscription, you gain access to guided workouts that display set instructions directly in the AR lens — so you can follow a coach’s session without memorising it beforehand. Integration with Garmin Connect, Apple Health, and Training Peaks makes it a strong option for triathletes juggling multi-sport training loads.
Optical Lens Compatibility and Fit
FORM offers a range of prescription lens inserts (sold separately), which is a significant advantage over competitors. The gasket seal is soft silicone and sits comfortably for sessions exceeding an hour. The goggles come in multiple strap colours and fit a wide range of head sizes. UV protection is included for outdoor use, though it’s worth noting that open-water AR functionality is limited without a paired GPS device.

Pros and Cons
✅ Pros
- Game-changing AR display — genuinely readable mid-stroke, doesn’t disrupt vision or technique
- Highly accurate lap detection — automatic, reliable, and works across all four strokes
- Rich post-swim analytics — SWOLF, split times, stroke efficiency, and trend tracking over weeks
- Prescription lens compatibility — a genuinely important feature rarely offered by competitors
- Structured in-goggle coaching — follow complex sessions without memorising every set
- Excellent third-party integration — Garmin, Apple Health, Training Peaks, Strava
- Comfortable for long sessions — silicone seal holds up well for 60–90 minute pool sessions
❌ Cons
- Ongoing subscription cost — full feature access requires a monthly or annual FORM Swim membership
- Heart rate requires a separate purchase — the FORM Heart Rate Monitor is an additional cost on top of the goggles
- Limited open-water GPS functionality — relies on a paired device; the goggles alone can’t track outdoor routes
- Display only in right lens — left-eye dominant swimmers may take time adjusting
- Price point is a barrier — not budget-friendly for casual or beginner swimmers

Who Are FORM Smart Swimming Goggles Best For?
Perfect For:
- Competitive club swimmers — anyone training for events who needs split accuracy and stroke-efficiency data to improve performance
- Triathletes — the third-party integrations with Garmin and Training Peaks make these a natural fit for multi-discipline athletes tracking workload across swim, bike, and run
- Swimmers with prescription needs — the optional prescription inserts make these accessible to a group largely ignored by the smart fitness wearable market
- Coached swimmers following structured plans — in-goggle set guidance is genuinely transformative for complex sessions with rest intervals and distance targets
- Fitness swimmers who feel their training lacks direction — the data and coaching plans provide a clear roadmap that poolside counting simply can’t match
Not Ideal For:
- Casual or occasional swimmers — the investment (goggles plus subscription) is hard to justify for once-a-week leisure swimming
- Predominantly open-water swimmers — without onboard GPS, outdoor route tracking requires a paired device, making the experience less seamless
- Budget-conscious beginners — at ~£199 before any extras, these are a premium product requiring genuine commitment to swimming as a sport
- Left-eye dominant swimmers who struggle to adapt — some users do report the right-lens-only display requires a short but real adjustment period
Our Verdict
After extensive pool testing, we’re confident that FORM Smart Swimming Goggles represent the most compelling piece of swimming technology currently available in the UK. The AR display is genuinely transformative — not a gimmick, not a distraction, but a real tool that changes how you train. Lap detection is reliable, analytics are deep, and the coaching plan integration earns its subscription fee for anyone swimming more than three times a week.
The caveats are real though: the ongoing subscription cost stings, heart rate monitoring costs extra, and open-water use is more limited than the marketing implies. These aren’t goggles for everyone. But for serious pool swimmers and triathletes, they’re comfortably the best option available — and they’re improving with every firmware update.

Frequently Asked Questions
Do FORM Smart Swimming Goggles work in open water?
FORM goggles do have an open-water mode, but they don’t have onboard GPS — so for accurate distance and route tracking outdoors, you’ll need a paired GPS device such as a Garmin watch. Stroke metrics and time data are still recorded in open-water mode without a paired device, but it’s a less complete experience compared to pool use.
Do you need a subscription to use FORM Smart Swimming Goggles?
Basic functionality — including real-time AR metrics, lap tracking, and app syncing — is available without a subscription. However, structured coaching plans, advanced analytics, guided workouts displayed in the goggles, and third-party integrations with platforms like Training Peaks require the FORM Swim subscription, which costs approximately £9.99/month or £79.99/year.
Are FORM goggles suitable for swimmers who wear glasses?
Yes — this is one of FORM’s standout advantages. Prescription lens inserts are available directly through the FORM website, covering a range of dioptre strengths. This makes FORM goggles accessible to short-sighted or long-sighted swimmers who can’t use standard goggles comfortably, a group largely overlooked by other swim-tech brands.
How accurate is the lap counting on FORM Smart Goggles?
In our extensive testing, lap detection was accurate on over 97% of lengths across freestyle, breaststroke, backstroke, and butterfly. The 9-axis IMU sensor detects turns and stroke changes automatically. Occasional miscounts can occur during very slow or interrupted tumble turns, but for the vast majority of pool sessions the tracking is highly reliable and requires no manual intervention.
How long does the battery last on FORM Smart Swimming Goggles?
FORM quotes approximately 16 hours of battery life for the goggles themselves, which is more than sufficient for even the longest training camps or open-water swims. In practice, regular pool swimmers will charge them once every week or two. Charging is via a magnetic dock and takes around 90 minutes from flat to full — a convenient setup for poolside use.
