FORM Smart Swim 2
Smart swimming goggles with a built-in heart rate monitor.
The Smart Swim 2 is the core FORM goggle — a pair of smart swimming goggles with a patented Waveguide AR display projecting nine real-time metrics into your line of sight, plus an integrated optical heart rate sensor that reads from the temple. No chest strap. No watch. No extra accessories. Heart-rate-based training built directly into the goggles themselves.
The heart rate sensor is the headline feature, and per FORM’s own white paper, it’s more accurate than the leading smartwatch for pool swimming — the wrist is a poor place to read heart rate while swimming because the watch loses contact and water disrupts the signal. The Smart Swim 2 reads from the temple, where contact is consistent throughout the swim. The result: zone-based training, threshold work, and recovery-zone aerobic swims work the same way they do on a bike or run, but actually in the pool.
The other eight metrics — pace, distance, time, stroke rate, stroke count, distance per stroke, split times, and calories — all display in the same waveguide. Customize through the FORM Swim App. Sync to Strava, Apple Health, TrainingPeaks, TriDot, Final Surge, and Garmin or Apple Watch for GPS pairing in open water. Race approved by World Triathlon, USA Triathlon, British Triathlon, PTO, and supertri. 30-day in-water trial, 2-year warranty, free shipping.

Nine Real-Time Metrics
What you see in the display while you swim.
Customize which metrics appear and on which eye through the FORM Swim App. Heart rate is the differentiator from Smart Swim 2 LT — eight of these are shared; HR is unique to Smart Swim 2 and PRO.

Why Smart Swim 2
The core FORM experience — heart rate built in.
Smart Swim 2 is the goggle for swimmers and triathletes who want heart-rate-based training in the water without strapping on extra hardware. The HR sensor reads from the temple, which is more reliable than wrist-based readings during swim strokes.

Inside the Smart Swim 2
Three features that earn the upgrade from LT.
The heart rate sensor is the headline. The extended strap mounts and updated silhouette also matter — they’re what makes the heart rate read consistent over a long swim.
❤️ Heart Rate
Integrated Temple Heart Rate Sensor
The Smart Swim 2’s defining feature is the optical heart rate sensor built into the goggle frame, reading from the temple. The temple is a more reliable location for heart rate during swimming than the wrist — water movement, stroke mechanics, and skin contact all degrade wrist-based HR during a swim. Temple contact stays consistent because the goggle strap holds it in place. Per FORM’s published white paper, the result is HR accuracy that exceeds the leading smartwatch for pool swimming.
- Optical heart rate sensor at the temple — consistent contact
- More accurate than the leading smartwatch (FORM white paper)
- Live BPM displays in the goggle while you swim
- No chest strap or watch required — heart rate is built in
- Enables zone-based training, threshold work, and aerobic intervals

?️ Display
Patented Waveguide AR Display
FORM’s patented Waveguide display projects nine real-time metrics into your line of sight as you swim. The display sits in front of one eye (switchable through the app) and floats out in front of you — no refocusing required to read it. Glance up, read your pace or heart rate, keep swimming. Mirrored lenses block 98% of harmful UV. Industry-leading anti-fog coating. The display remains visible for prescriptions up to -3.

? Fit
Extended Strap Mounts + 5 Nose Bridges
The Smart Swim 2 has extended temple mounts (an upgrade over the original Smart Swim) that improve fit consistency and keep the heart rate sensor in stable contact through long sessions. The frame ships with 5 interchangeable arched nose bridges (XS–XL), replaceable contoured eye seals, and a fully adjustable strap. The result: a leak-free, comfortable fit across face shapes — and a stable HR signal.

Common Questions
Frequently asked questions.
Answers to what most buyers ask before ordering the Smart Swim 2.
The Smart Swim 2 has an optical heart rate sensor built into the frame that reads your pulse from your temple. Live heart rate displays in the in-lens AR display while you swim. The temple is a better location for swimming HR than the wrist — water and stroke mechanics disrupt wrist sensors, but temple contact stays consistent because the goggle strap holds it in place. Per FORM’s published white paper, the result is HR accuracy that exceeds the leading smartwatch for pool swimming.Smart Swim 2 LT is the entry point — in-lens AR display, 8 metrics, no heart rate. Smart Swim 2 (this product) adds an integrated heart rate sensor at the temple for 9 metrics total, plus extended strap mounts for stable HR contact. Smart Swim 2 PRO includes everything in Smart Swim 2 plus premium Corning® Gorilla® Glass 3 lenses for maximum scratch resistance and long-term clarity.Nine real-time metrics: heart rate, pace, distance, time, stroke rate, stroke count, distance per stroke (DPS), split times, and calories burned. Customize which metrics appear on the display and which eye it sits on through the FORM Swim App.Yes. Smart Swim 2 is designed for both pool and open-water swimming and is race approved by World Triathlon, USA Triathlon, British Triathlon, PTO, and supertri. In open water, pair with a Garmin or Apple Watch for GPS-based distance and pace. The HR sensor works equally well in pool and open water — same temple-based reading.Yes. The Smart Swim 2 ships with 5 interchangeable arched nose bridges (XS to XL) and a fully adjustable strap. Replaceable contoured silicone eye seals are designed for long sessions without leaking or pressure marks. The extended temple strap mounts are designed specifically to keep the HR sensor in stable contact across face shapes. If the fit isn’t right, FORM offers a 30-day in-water trial.The display is designed not to require focus — it floats in front of you, so you don’t refocus to read it. For prescriptions stronger than -2, some users find it harder to read. At -3, it’s near the edge of usability. FORM recommends using the 30-day in-water trial to confirm visibility for your specific prescription before committing.Up to 14 hours of swim time per charge, depending on display brightness and feature use. For most swimmers, that’s several weeks of typical training between charges. Charges via magnetic USB cable included in the box.No. Heart rate displays in the goggles and syncs to the FORM app without any Premium subscription. Premium adds the coaching layer (HeadCoach™, guided workouts, training plans, Script), but core goggle features — including all 9 metrics, HR, app sync, and automatic sharing to Strava and Apple Health — work fully without it. Free 1-month Premium trial included with every goggle activation.Rinse with fresh water after every swim — chlorine and salt water shorten the life of the anti-fog coating. Do not touch the inside of the lenses (the coating is on the inner surface and is sensitive to skin oils). Store in the ventilated case included in the box. Full care instructions in the FORM app.Smart Swim 2 includes a 2-year limited manufacturing warranty plus a 30-day in-water trial. If the goggles aren’t right for any reason in the first 30 days, return them. After that, the warranty covers manufacturing defects for the full 2 years.
