Where I’d start: smart swim goggles with a heads-up display still come from exactly two companies as of this writing, and if you swim structured sets and want a coach’s numbers pushed straight into your field of vision, the FORM Smart Swim 2 ($199) is the pick — it’s the cheapest FORM tier with a heart rate sensor built in. If you just want pace, time, and lap count with nothing recurring to pay afterward, the Holoswim 2S ($99) does exactly that and stops there. Skip the whole FORM lineup if a $119-a-year renewal for the features that make the goggles worth owning would bother you every single year — that’s not a hidden fee, it’s just the business model.
A Year or More In: What Owners Actually Report
Two companies make a HUD swim goggle right now, which is a small enough field that the honest question isn’t “which one wins” so much as “what does either one look like after you’ve actually owned it a while.” Neither has been in my hands for this piece — what follows comes from named long-term reviews and swimmer forums, not a testing lab.
The most complete long-haul account I found is Slowtwitch’s, which put roughly 250 swims and two and a half years on a pair of FORM goggles and reported, plainly, no leaking, no fogging, no scratched lens, and no display fade in that time. That’s a genuinely good result for a $150-plus electronic device worn against your face in chlorinated water. Set against that: a Slowtwitch Forum thread from December 2024 has one swimmer describing FORM goggles that “leak sometimes, give me really bad goggle eyes and seem particularly heavy,” and another reporting a unit that failed from leakage “a little over a year” in — close enough to FORM’s own 2-year warranty window that it’s worth knowing about before you buy, not after. A separate, earlier thread from September 2023 raised the same leak complaint; one reply there pinned it on fit and suction rather than a hardware defect, which tracks with how any swim goggle actually fails — the seal is doing the work, and faces vary.
Holoswim doesn’t have an equivalent multi-year record yet, in either direction. The brand and its goggles are newer, English-language forums haven’t accumulated the same volume of long-term threads FORM has, and I couldn’t find a comparable two-and-a-half-year account to hold up next to Slowtwitch’s. That’s not a mark against Holoswim so much as an honest gap: buy it knowing you’re an earlier adopter of the hardware than a FORM buyer would be, not a later one.
The other recurring complaint, from DC Rainmaker’s review, is FORM’s optical heart rate sensor, which he describes as “all or nothing” — either reading accurately for a whole swim or dropping out and taking several lengths to reconnect. He also names limited peripheral visibility in open water as “the singular reason” he won’t use FORM as a daily open-water driver, which matters if you swim anything other than a straight pool lane.
The First Season: What the Subscription Actually Adds Up To
Every FORM tier can run without ever paying a cent past the hardware price — basic pace, distance, and lap tracking work out of the box. What costs money is FORM’s optional coaching membership, $119 a year or $15 a month, which unlocks the HeadCoach technique analysis and structured workout plans that are most of the reason to want a FORM goggle over a cheaper alternative in the first place. Holoswim’s entire lineup, by contrast, ships its full advertised feature set with nothing recurring, ever, on any of its three tiers.
Laid out as a running total rather than a per-swim rate, here’s where each option actually sits by the end of one season and by the one-year mark — assuming you do add FORM’s membership, since skipping it mostly defeats the point of buying FORM over Holoswim in the first place:
| Model | Hardware Price | Ongoing Cost | Total After 6 Months | Total After 1 Year |
|---|---|---|---|---|
| Holoswim 2S | $99 | None | $99 | $99 |
| Holoswim 2 Pro | $149 | None | $149 | $149 |
| Holoswim 3 Pro | $249 | None | $249 | $249 |
| FORM Smart Swim 2 LT | $149 | $119/yr membership | $208.50 | $268 |
| FORM Smart Swim 2 | $199 | $119/yr membership | $258.50 | $318 |
| FORM Smart Swim 2 PRO | $259 | $119/yr membership | $318.50 | $378 |
The gap that actually matters isn’t between FORM’s three tiers or Holoswim’s three tiers — tier for tier, FORM and Holoswim start out close together. It’s the $119 FORM adds every single year, indefinitely, for as long as you want the coaching features turned on. A Holoswim 3 Pro costs more upfront than any FORM tier, and it’s still cheaper than a FORM Smart Swim 2 LT by the start of year two.
The First Few Swims: What “HUD” Actually Means, and Who’s Really Selling One
A HUD swim goggle projects live numbers — pace, lap count, stroke data — directly into your field of vision through a small in-lens display, so you’re not turning your head to squint at a pace clock or waiting until you’re toweling off to check a watch. Both brands here build it the same basic way: a waveguide or micro-display set into one lens, paired with motion sensors that detect strokes, walls, and rest periods on their own, so the display lights up mid-swim and goes quiet when you stop. No button-pressing required.
Be skeptical of any roundup that lists five or six HUD brands this year — the real field is thin, and it hasn’t grown since this piece first published. FINIS retired its Smart Goggle line at the end of 2025; the app still works for owners who registered by the end of January 2026, and replacement lenses are still sold while supplies last, but it isn’t a current pick. Garmin has done nothing but get speculated about — a March 2026 report chased an odd camera angle in a Garmin video that most likely just showed FORM’s goggles, and nothing has shipped or leaked further since. Speedo did launch something new this past August: the Speedo iQ, a $189 sensor module that clips into its Vanquisher 3.0 goggles and reports pace and stroke data to your phone after your swim — worth knowing about if you’ve seen it mentioned elsewhere, but it has no in-goggle display at all, so it’s a different category, not a third HUD competitor. As of this month, FORM and Holoswim are still it.
The Six Smart Swim Goggles Worth Knowing About
Here’s what each tier actually gets you, and who should skip it.
FORM Smart Swim 2 LT — $149
The LT carries FORM’s full AR display, SwimStraight compass, and HeadCoach technique analysis — the only thing it drops versus the step-up model is the optical heart rate sensor. Battery is rated at 14 hours, and it weighs 68 grams. Best for: swimmers who want FORM’s coaching layer but don’t train by heart rate zone. Skip this if heart rate is actually part of your training plan — the next tier up adds it for $50 more.
FORM Smart Swim 2 — $199
The core model, adding a built-in optical heart rate sensor on top of the LT’s feature set: heart rate, pace, stroke rate, distance, calories, stroke count, distance-per-stroke, and split times, at 69 grams. This is the cheapest way into FORM with heart rate data included. Skip this if you already know you don’t want a $119-a-year membership — without it, you’re paying $50 more than the LT for a heart rate sensor you won’t get much use out of.
FORM Smart Swim 2 PRO — $259
The PRO adds Gorilla Glass lenses and a renewable anti-fog spray kit, rated for roughly 175 swims, on top of the standard model, at a small weight penalty (73.4 grams versus 69). Best for: swimmers hard enough on lenses that scratch resistance is worth $60. Skip this if that’s not you — Slowtwitch’s two-and-a-half-year, 250-swim review found no lens damage on the standard model either.
Holoswim 2S — $99
The cheapest HUD goggle either brand sells: pace, time, distance, and lap count on a 128×64 in-lens display, rated IPX8, weighing 70 grams, with roughly 4 hours of battery per charge. No subscription, on this tier or any other Holoswim tier. Best for: finding out whether an in-lens display works for your stroke before spending more. Skip this if 4 hours of battery is genuinely tight for how you train — the 3 Pro quadruples that in the pool.
Holoswim 2 Pro — $149
The middle tier adds TÜV-certified anti-fog lenses and more than 120 structured training templates, at 74 grams. It’s priced $10 higher than it was when this piece first ran, confirmed directly against Holoswim’s own site this month rather than carried over from an old listing. It’s also one of two Holoswim tiers, with the 2S, that already works with HoloSport’s HandPlus B2 heart-rate accessory — something the flagship 3 Pro still can’t do as of publication. Skip this if heart rate matters enough that you’d rather have it built in — FORM’s $199 tier does that natively, this one needs an added accessory.
Holoswim 3 Pro — $249 (regularly $319)
The only HUD goggle from either brand with its own GPS and compass, adding a real open-water mode with average pace, rest time, SWOLF, water temperature, and water depth on top of the pool metrics. Battery runs up to 16 hours in the pool but drops to about 5 with GPS running outdoors. Holoswim backs it with a 3-year warranty, a year longer than the rest of its own lineup or anything FORM publishes. The one thing it still can’t do: HoloSport said heart-rate support for this tier was “expected in September 2026.” That’s now, and as of publication it hasn’t shipped. Best for: swimmers who train both pool and open water and don’t want to pair a separate watch for outdoor distance. Skip this if heart rate data matters more to you than GPS — the cheaper 2 Pro already has it, this one still doesn’t.
Every Model, Side by Side
| Model | Price | HUD Data | Heart Rate | Battery | Warranty |
|---|---|---|---|---|---|
| FORM Smart Swim 2 LT | $149 | Pace, stroke rate, distance, splits | No | ~14 hrs | 2 years |
| FORM Smart Swim 2 | $199 | Adds heart rate, calories, DPS | Yes, built in | ~14 hrs | 2 years |
| FORM Smart Swim 2 PRO | $259 | Same as Smart Swim 2 | Yes, built in | ~14 hrs | 2 years |
| Holoswim 2S | $99 | Pace, time, distance, lap count | Via HandPlus B2 accessory | ~4 hrs | 2 years |
| Holoswim 2 Pro | $149 | Same as 2S, plus training templates | Via HandPlus B2 accessory | ~4 hrs | 2 years |
| Holoswim 3 Pro | $249 | Adds SWOLF, water temp/depth, GPS | Not yet supported | 16 hrs pool / 5 hrs GPS | 3 years |
Which One Actually Fits Your Training
Structured, coached training: FORM Smart Swim 2 or PRO, membership included. Nothing else here has FORM’s depth of technique analysis and workout library — you’re paying for that specifically, not just the hardware.
Refuse to pay a subscription, on principle or on budget: any Holoswim tier. All three ship their full feature set with nothing recurring.
Pool-only, and heart rate zones matter: FORM Smart Swim 2. It’s the cheapest tier from either brand with heart rate built in rather than bolted on as an accessory.
Pool and open water both: Holoswim 3 Pro, for now the only goggle here with its own GPS — though its 5-hour open-water battery is a real ceiling on how long a swim it’ll cover.
Just curious whether a HUD goggle is for you at all: Holoswim 2S. Ninety-nine dollars is a reasonable price to find out.
A Few More Things Worth Knowing
Do I have to pay a subscription for either brand?
Only if you buy FORM and want its coaching features. Basic pace and lap tracking works on every FORM tier without paying anything past the hardware price; the $119-a-year membership unlocks HeadCoach technique analysis and structured plans. Holoswim requires no subscription on any tier, ever.
Can I use one of these in open water, not just a pool?
Most current HUD goggles are built around pool laps. The Holoswim 3 Pro is the exception, with its own GPS and compass for a real open-water mode, though its battery drops to about 5 hours with GPS running. FORM’s goggles include a compass for direction but lean on a paired watch for open-water GPS distance.
What happened to FINIS Smart Goggles?
FINIS retired the line at the end of 2025. The companion app still works for owners who registered by January 31, 2026, and replacement lenses are still sold while supplies last, but it’s no longer a current pick — despite still turning up in older comparison articles.
If a full GPS multisport watch fits your training better than goggles, the guide to smartwatches that survive open water covers six current options for swimmers and triathletes.
