Noise launched the ColorFit Pulse 4 in India on April 24, 2024. It combines a 1.85-inch AMOLED screen with phone-linked Bluetooth calling and basic wellness tracking. As of August 18, 2026, Noise’s official store listed silicone-strap variants at ₹2,499 and metal-link variants at ₹2,999. It is a budget companion watch, not a standalone cellular watch or a medical device.
Launch date, availability and current price
The ColorFit Pulse 4 is a 2024 model, not a new 2026 launch.

The standard model launched at ₹2,499 and the Mesh Metal version at ₹2,799. A ₹250 website discount was reported as a launch promotion, not a current offer, by Gizmochina.

What the display and design offer
The large, square 1.85-inch AMOLED panel is the watch’s main visual draw at this price. AMOLED can show deeper blacks and stronger contrast than a typical LCD, while Noise lists more than 100 customisable watch faces and cloud-based faces. The stated peak brightness is up to 600 nits, but that number alone cannot guarantee readability in every outdoor situation: reflections, face design and actual brightness setting matter too.

Bluetooth calling requires your phone
Tru Sync supports incoming and outgoing calls through the watch when it is connected to a nearby smartphone. Call management includes caller information, call rejection, call logs and speed dial for up to 10 contacts, as reported by The Indian Express. This is not cellular calling: the watch does not provide independent mobile-network service or replace a phone.

Pairing and call setup
- Install and open the NoiseFit app, then pair the watch with your phone through the app.
- Grant the Bluetooth, notifications, phone and microphone permissions requested during setup.
- Complete the separate calling-Bluetooth pairing if the setup prompts you to do so.
- Keep the phone within Bluetooth range. On Android, allow NoiseFit to run in the background and review battery-optimisation restrictions.
Exact permission names and menus vary by phone and app version. If calls stop appearing, check that the phone’s Bluetooth is on, the calling connection remains paired, and Do Not Disturb is off on the watch. Noise says the calling Bluetooth connection can switch off after the watch has been disconnected from the phone for more than three minutes; manually re-enable it on the watch and reconnect the calling channel if needed. See Noise’s call troubleshooting guidance.

Noise lists heart-rate monitoring, SpO2 readings, sleep and stress tracking, and female-cycle tracking, along with step and activity tracking and more than 100 sports modes. These are wellness features; the available product information does not establish medical-grade accuracy or clinical validation. Treat readings as estimates, not diagnoses or substitutes for medical equipment or professional advice.

Fit and movement can affect readings. Noise’s FAQ says the heart-rate sensor should sit against the skin without a gap. Wear the watch snugly and remain still for spot readings; if a reading matters for a health decision, use an appropriate medical device or consult a clinician.

Noise claims up to seven days of typical use, up to 30 days on standby and charging in up to two hours. These are manufacturer estimates, not independently measured battery-test results. Always-on display, brightness, frequent calls, notifications, monitoring frequency, workout tracking and watch-face behaviour can all change actual endurance.
Noise rates the watch IP68 and describes protection under stated conditions of approximately 1.5 metres underwater for up to 30 minutes. The rating should not be read as swimming approval: Noise explicitly says not to use the watch while swimming and warns against saunas, hot water and ocean water. See the official product information.
Smart features and everyday dependencies
Beyond calling and health tracking, Noise lists an AI voice assistant, stopwatch, timer, alarm, reminders, weather, music control, calculator, vibration alerts, Do Not Disturb, brightness control, a functional crown, wrist-awake, phone tracking and built-in games. Notifications can include services such as SMS, WhatsApp, Instagram, Gmail and Telegram, subject to phone permissions and a working Bluetooth connection. App notifications are not guaranteed to behave identically across Android and iPhone; NoiseFit permissions, phone settings, background operation and range all affect delivery.
Quick Recap
Who should consider the Pulse 4?
- Consider it if you want a large AMOLED screen, basic phone-linked calling and everyday wellness tracking at the listed price.
- Consider it if you already use NoiseFit and want to stay with that app and product ecosystem.
- Compare newer watches first if you are buying on price alone: the Pulse 4 launched in 2024, so its original positioning may not reflect what else is available now.
- Look elsewhere if you need independent cellular calls, swimming suitability, medical-grade readings or advanced training analysis. The available sources do not establish built-in cellular connectivity or independent accuracy testing for this watch.
What to check before checkout
- Confirm whether the selected version is silicone or metal-link and check its current price and stock.
- Check delivery terms and the one-year manufacturing warranty on the seller’s listing.
- Make sure you are comfortable keeping a compatible smartphone nearby for calls and app-dependent notifications.
- Do not buy it on the assumption that IP68 makes it suitable for swimming.
