If you’re tired of chest straps but still want training-grade heart rate accuracy, the Holoswim HandPlus is making a strong case that optical monitoring has finally caught up.
The HandPlus is a training-focused optical heart rate monitor from Holoswim — the brand behind the popular AR swim goggle line — built for athletes who want reliable zone-based data without the hassle of a chest strap. Using advanced multi-channel optical sensing, it claims heart rate zone accuracy within 0.2% of traditional chest strap monitors. Rather than overwhelming you with smartwatch-style features, HandPlus keeps it focused: heart rate zones, HRV, SpO₂, body temperature, and vibration alerts when you cross zone thresholds. A shake-to-activate motion starts recording automatically — no buttons, no missed sessions. Up to 72 hours of offline storage captures workouts even without your phone nearby. Bluetooth and ANT+ connectivity covers Garmin, Apple Watch, bike computers, and Holoswim’s AR goggle systems. Real-time data displays on your iOS lock screen or Dynamic Island. Every unit includes a 30-day return policy and 1-year limited warranty under the HandPlus Care+ program.
What People Love About It:
1. Shake-to-activate means no pre-workout button pressing — recording starts automatically so every session is captured
2. Dual Bluetooth and ANT+ connectivity slots easily into existing setups with Garmin, Apple Watch, bike computers, or Holoswim AR goggles
3. Vibration zone alerts let you stay in your target HR zone without checking a screen mid-workout
4. 72 hours of offline storage means workouts are logged even in the pool, on trails, or anywhere your phone isn’t present
5. Chest-strap-free design with training-grade claimed accuracy is a genuine draw for athletes who find traditional straps uncomfortable or disruptive
What Some People Don’t Love:
1. As a newer product, there’s limited long-term user review data to independently validate the 0.2% accuracy claim across all activity types
2. The intentionally minimal feature set won’t replace a smartwatch for athletes who also want GPS, sleep tracking, or notifications
3. Optical HR sensors can still struggle during peak-intensity movements where arm motion disrupts the signal
4. Casual fitness users may find the price harder to justify if basic wrist-based tracking would meet their needs
5. The Holoswim ecosystem integration is a highlight feature, but buyers outside that ecosystem won’t fully leverage it
FAQs:
Q: Does HandPlus work without a smartphone during workouts?
A: Yes — 72 hours of offline storage lets it record independently. Data syncs afterward via the Holosport app.
Q: How does it compare to a chest strap for accuracy?
A: Holoswim claims heart rate zone accuracy within 0.2% of chest strap monitors. Zone accuracy — not beat-for-beat precision — is the key metric for structured training, and that’s what HandPlus is optimized for.
Q: Where is it worn on the body?
A: Wrist or upper arm. Upper arm generally provides a more stable optical signal during high-intensity activities like running, cycling, or swimming.
Pros: No chest strap, shake-to-activate, Bluetooth + ANT+, 72h offline storage, vibration HR zone alerts, Holoswim ecosystem compatible | Cons: Limited review history, no GPS or smartwatch features, optical accuracy may vary at peak intensity
