FORM Swim Goggles Review (2026)
FORM swim goggles review: are they worth it? Swim 1 vs Swim 2 compared on display, GPS, and price, plus how they stack up against other smart swim goggles.
Swim 1 versus Swim 2 — head-to-head on display clarity, heart rate accuracy, open water GPS, and price. Plus a side-by-side against the traditional watch-plus-goggles setup most swimmers already own.
FORM swim goggles put real-time pace, stroke rate, distance, and heart rate directly in your line of sight while you swim. No glancing at a wrist, no stopping at the wall to check a watch — the data floats in the lower-right corner of your goggle lens, roughly a meter ahead, like a dashboard for your face. I've coached on deck for 15 years and watched swimmers squint at pace clocks, miscount laps, and guess their stroke efficiency mid-set.
These goggles solve a genuine problem: getting feedback during the swim, not after the set ends.
At $199 for the Swim 1 and $249 for the Swim 2, the question is whether that in-goggle AR display justifies the price — and which model matches your training. This FORM swim goggles review compares the two models directly, stacks them against a Garmin watch setup, and tells you exactly who should buy them and who should keep their $15 Speedo Vanquishers.
No marketing fluff, no affiliate-driven enthusiasm. Just what a coach would tell you on deck.
FORM Swim Goggles Review: The Quick Verdict
FORM swim goggles are worth it for pool and open water swimmers who train with pace, stroke rate, or heart-rate targets and want that data in their line of sight instead of on a wrist. They are the most polished smart swim goggles available — a genuine AR head-up display, not a gimmick. For casual swimmers doing two easy sessions a week, they are overkill.
Which model? Buy the FORM Swim 2 ($249) if you ever swim open water — it has built-in GPS the Swim 1 lacks, plus a brighter display. Buy the FORM Swim 1 ($199) if you swim only in a pool and want the cheapest way into real-time metrics; the core pool tracking is identical. Compared with other smart swim goggles, FORM wins on display clarity and app maturity, while a Garmin or Apple watch is the better pick if you want one device for swimming, running, and cycling.
How FORM Smart Goggles Work
Both FORM models use a waveguide display — a transparent optic that projects swim metrics onto the lens without obstructing your forward vision. The numbers appear suspended in space, similar to a car's head-up display, so you see the lane line and your pace simultaneously. The default rotation shows elapsed time, distance covered, and pace per 100 meters.
A firmware update adds stroke rate, SWOLF score, and stroke count as swipe-able screens.
A single physical button sits on the right goggle frame. Tap it to cycle between metric screens during a swim — no need to break stroke or touch a watch. The goggles use internal accelerometers and gyroscopes to detect turns, count laps, and identify stroke type (freestyle, backstroke, breaststroke, butterfly). Pool length is set manually before the session.
For open water, the Swim 2 adds GPS-based tracking with satellite positioning built into the goggle frame.
Glance at the display once every 4 to 6 breaths — the same cadence you'd use for open water sighting. The data should inform your effort, not become the focus of the swim. If you find yourself staring at your stroke rate on every pull, turn the display off for half the workout and swim by feel. The goggles still record everything in the background.
FORM Swim Goggles Review: Swim 1 vs Swim 2 Compared
FORM launched the Swim 1 in 2019 and the Swim 2 in 2023. The core idea — an AR head-up display inside a goggle — is unchanged between generations, but the Swim 2 adds features that directly address the Swim 1's biggest limitation: pool-only tracking. If you train outdoors in lakes or oceans, the Swim 1 is a non-starter. The comparison table below lays out the feature differences that matter for training, skipping spec-sheet filler.
The Swim 2's headline feature is open water GPS. If you swim in lakes, oceans, or reservoirs, the Swim 2 tracks your route, distance, and pace outdoors — the Swim 1 cannot. This alone justifies the $50 price difference for any open water swimmer. For pool-only swimmers, the decision is tighter. Both models deliver the same core pool metrics, and the Swim 1's 16-hour battery already covers a full week of 2-hour sessions between charges.
Heart rate support works identically on both: neither has a built-in optical sensor in the goggle itself. You pair an external chest strap or optical armband via ANT+ or Bluetooth, and heart rate appears alongside pace and distance in the display. FORM sells a proprietary temple-mounted HR sensor for $79, but any standard chest strap or armband that broadcasts ANT+ or BLE will work.
This matters because a $50 Garmin HRM-Swim chest strap gives you HR data on both goggle models without buying FORM's accessory.
Heart Rate Training with In-Goggle Feedback
Wearing a chest strap in the pool has always been awkward. The strap slides down on push-offs, and even when it stays put, the data is useless unless you can see it mid-swim. FORM solves the visibility problem: heart rate appears in your goggle alongside pace and distance, so you can hold a specific beats-per-minute range for threshold sets without a coach shouting splits from the deck.
A lactate threshold set — 10 x 100m on 1:45 holding 165 to 175 bpm — becomes genuinely trainable without external feedback. You see your HR drift upward across the set, you know when you're fading before your pace drops, and you adjust effort in real time. Each interval leaves a heartbeat trace you can review later in the app. This turns a generic 10 x 100 into a targeted physiological session.
If you train with heart rate zones, use the swim workout generator to build sets targeting GA1 (135–150 bpm), GA2 (150–165 bpm), or WA (165+ bpm). The generator keeps exact distances, send-off times, and zone labels in AquaPlan and the PDF. AquaPlan's Garmin-compatible FIT export carries supported workout steps but does not currently encode heart-rate or training-zone targets.
If your FORM setup supports live heart-rate display, use FORM's current instructions to configure it separately.
Chest strap HR lags 3 to 5 seconds behind actual effort in cold water. If you're doing short 25m or 50m sprint intervals, heart rate data arrives too late to be actionable. Save HR monitoring for sets of 100m or longer, where the lag is a smaller fraction of the interval and the trend over multiple repeats is what matters.
FORM Swim Goggles Review: Smart Goggles vs Traditional Watch Setup
A Garmin swim watch or Apple Watch tracks swim metrics accurately — distance, stroke type, SWOLF, pace, heart rate. The problem is accessing that data mid-swim. A wrist-based display requires you to stop, lift your arm, and read the screen, which costs 2 to 3 seconds per check. Across a workout with 20 intervals and a data check after each, that's a full minute of your session spent staring at your wrist instead of breathing.
FORM eliminates that interruption entirely.
For threshold work, pace-controlled sets, or stroke-rate drills, having data in your goggles changes how you train. You adjust effort mid-length instead of at the wall. A swimmer holding 1:30/100m pace can see the instant they drift to 1:32 and correct it within the same 50 — no watch check required. That real-time correction loop is the feature that justifies the goggles for serious pool swimmers.
The trade-off is cost and versatility. A pair of mirrored Speedo Vanquishers costs $15. A Garmin Forerunner tracks running, cycling, and swimming for $200 to $400. FORM goggles track only swimming and cost $199 to $249 — plus another $79 if you want the FORM HR sensor. If you're a triathlete who already owns a multisport watch, FORM adds a dimension your watch physically cannot provide: real-time visual feedback without stopping.
That's a specialized upgrade, not a replacement.
For swimmers who want structured training guidance without the gear investment, browse the 130+ curated training plans and use the pace clock like swimmers have for decades. A printed workout sheet with send-off times and zone targets, paired with any $15 pair of goggles, has produced fast swimmers since before anyone dreamed of AR displays. The goggles help.
They don't replace the work.
Who Should Buy FORM Goggles — And Who Should Skip
Buy the Swim 2 if you swim open water regularly. The GPS tracking, open water pace per 100m, and route mapping are the reason this model exists. At $249, it's a dedicated open water computer attached to your goggles — no wrist device required. Triathletes training in lakes and reservoirs should treat this as a swimming-specific investment, separate from their bike computer and running watch.
Buy the Swim 1 if you swim exclusively in a pool and want the cheapest entry to real-time metrics. The Swim 1 has been discounted since the Swim 2 launched, and for pool swimming the feature gap between models is small: display brightness and battery life account for most of the difference. If you don't need outdoor GPS, save the $50 and put it toward a chest strap HR sensor.
Skip both if you swim casually — two 30-minute sessions per week without structured sets or pace targets. The goggles won't make you faster. They'll give you data you won't use and a $250 piece of electronics that needs charging, firmware updates, and careful post-swim rinsing. Spend the money on 8 to 10 coached sessions or a technique workshop. You'll get more speed from fixing your catch than from knowing your stroke rate is 62.
Skip both if you rely on prescription lenses. FORM goggles don't offer prescription inserts or corrective options. They fit over contact lenses, but swimmers with moderate to strong prescriptions may find the waveguide display difficult to read without corrected vision. The data appears at what your eye perceives as roughly 1 meter away — if that focal distance is blurry, the display won't be usable.
