If you want your heart-rate data to actually mean something during intervals and races, a dedicated monitor still beats your wrist watch. Optical sensors on the wrist lag and smooth out fast changes; a chest strap reads the electrical signal of your heart directly, so the numbers track reality. The trade-off is comfort, which is where forearm armbands come in. This guide splits the picks by what you're actually training for, and leans hard on the two things people forget to check: dual ANT+/Bluetooth connectivity so the thing pairs with your watch, your phone and the gym treadmill, and the battery you'll have to live with.

First, chest strap or armband?
A chest strap measures heart rate electrically, the same principle as a clinical ECG, which is why it stays honest during intervals, sprints and anything with sharp spikes. An optical armband (the Verity Sense, the COROS) shines light through your skin to read blood flow, trades a little accuracy at very high intensity, and is far more pleasant to wear, especially for strength work where a band across your chest is genuinely annoying.
The rule of thumb: if you race, do structured intervals, or care about training zones being right, get a chest strap. If you mostly do steady cardio and strength and you've quietly hated every chest strap you've owned, get an armband. Both beat your watch's wrist sensor for training.
What actually matters when buying
Connectivity. ANT+ lets one strap broadcast to several devices at once (watch, bike computer, gym machine), while Bluetooth LE pairs with phones and apps. Dual-band straps carry both, so they'll talk to anything. Most picks here are dual-band; the COROS armband is Bluetooth-only, so confirm your watch or app supports Bluetooth pairing before you buy it.
Battery. Coin-cell straps run roughly a year at an hour a day, then you swap a CR2025 or CR2032. Rechargeable ones save you the coin cells but need topping up. Armbands run per-charge, so charging discipline matters.
The rest. Water resistance if you swim, onboard memory if you train without a phone nearby, and fit, because a loose or dry strap drops out mid-session no matter how good the sensor is.
1. Polar H10 — best overall accuracy
Best for: anyone who wants the numbers to be right, full stop.
This is the strap sports scientists actually use to validate other devices, which tells you most of what you need to know. Polar positions it as the gold standard, and it earns that: dual Bluetooth LE plus ANT+, so it can feed two Bluetooth apps and an ANT+ device simultaneously, WR30 water resistance, and built-in memory that records one session standalone via Polar Flow. Battery is roughly 400 hours on a user-replaceable CR2025, about a year at an hour a day.
The catch: it's a chest strap, with all the damp-electrode, snug-fit faff that implies. If you've never got on with straps, the accuracy crown won't change your mind.
Where to get it: Polar Singapore official store.
2. Garmin HRM-Pro Plus — best for triathletes and multisport
Best for: Garmin watch owners who swim, and anyone chasing running form data.
This is the most multisport-minded strap here. It transmits over ANT+ and Bluetooth LE at once, captures running dynamics like vertical oscillation, ground contact time and stride length, and crucially stores heart rate through a pool swim then replays it to your Garmin watch afterwards, plus treadmill pace and distance indoors. Battery is about a year on a replaceable CR2032 coin cell behind a tool-free door.
The catch: you pay a premium for features that only fully pay off inside the Garmin ecosystem. If you don't own a Garmin watch and don't care about running dynamics, you're overbuying.
Where to get it: Garmin Singapore official store or Pro Cycle Bikes.
3. Wahoo TRACKR — best rechargeable chest strap
Best for: people who never want to think about coin cells again.
Wahoo's newer ECG strap ditches the coin cell for a USB-C rechargeable battery rated at 100-plus hours. It runs ANT+ plus Bluetooth with up to three simultaneous Bluetooth connections, carries IPX7 water resistance, and the strap fits up to a roughly 127cm chest. The pod is light and unfussy, and the magnetic charge cable is the same idea as the one on Shokz headphones.
The catch: rechargeable cuts both ways. Forget to charge it and you're stuck, whereas a coin-cell strap quietly soldiers on for months. IPX7 also means splash-and-sweat resistant, not a swimming strap.
Where to get it: Bike Stop Singapore.
4. Wahoo TICKR 2 — best value chest strap
Best for: adding a proper strap to Peloton, Zwift, spin or gym cardio without overspending.
The cheapest sensible way onto this list. It's a reliable dual-band strap, ANT+ plus up to three simultaneous Bluetooth connections, so it broadcasts to your watch, phone, bike computer and the gym machine at the same time. Coin-cell powered, no frills, does the job.
The catch: no onboard memory, so it has to be paired to a phone, watch or app to record, and there are no running dynamics or stored swim HR. It's a clean live broadcaster, which is all most gym and trainer users need, but if you want to train phone-free or grow into multisport, look up the list. (Wahoo's pricier TICKR X is the one that adds offline recording.)
Where to get it: Pro Cycle Bikes Singapore.
If the TICKR is sold out or you're tied to one brand, two clean alternatives at similar money: the Garmin HRM-Dual (~S$99-115), a no-frills ANT+ and Bluetooth LE broadcaster built for broad compatibility with trainers and apps like Zwift and Tacx, and the Garmin HRM 200 (~S$109), which adds HRV and a machine-washable strap in two sizes for Garmin watch owners who don't need the Pro Plus extras.
5. Polar Verity Sense — best optical armband
Best for: anyone who finds chest straps unbearable but still wants real data.
Worn on the forearm or bicep, this is the most versatile no-strap option going. It's dual Bluetooth plus ANT+, runs up to about 30 hours per charge depending on mode, and holds 16MB of memory for roughly 600 hours of stored sessions. WR50 water resistance with a dedicated swimming mode and a goggle-strap clip make it genuinely pool-capable, which is rare for an armband.
The catch: it's optical, so it trades a little accuracy during very high-intensity intervals. For steady efforts, strength and swimming it's excellent; for all-out track sessions a chest strap still wins.
Where to get it: Polar Singapore official store.
6. COROS Heart Rate Monitor — best armband for battery life
Best for: set-and-forget wearers who hate charging.
The endurance pick. About 38 hours of continuous use, 80 days on standby, a quick-charging battery that tops up in under two hours via magnetic USB, and built-in wear detection that powers it on and off automatically. Bluetooth with up to three simultaneous connections.
The catch: Bluetooth-only, no ANT+. If your watch, bike computer or gym machine needs ANT+, this won't pair, so confirm Bluetooth support first.
Where to get it: Red Dot Running Company Singapore (stock can sell out).
How to choose
Runners and gym-goers who want accuracy on a budget: TICKR 2. Want the best numbers regardless: H10. Triathletes in Garmin's world: HRM-Pro Plus. Sick of coin cells: TRACKR. Can't stand chest straps: Verity Sense, or the COROS if battery life and ANT+-free pairing suit you. Whatever you pick, buy from an authorised local seller and double-check ANT+ versus Bluetooth against the gear you already own before you pay.
