TOOBUR IDW16 Alexa Smart Watch

For a fitness routine, voice matters most when your hands are busy. Think sweaty fingers after a run, a yoga mat, or a kettlebell in each hand. A quick request sets a reminder to stretch later or checks whether rain is coming before the evening walk.

Everyday uses that fit around training:

• set a reminder to drink water or stand up after a meeting
• ask for the weather before heading out for steps
• switch compatible smart lights or plugs on as you get home from the gym
• add a to-do without stopping the cool-down

Alexa on the IDW16 runs through the VeryFit app on your phone. The watch listens and shows the answer, while the phone handles the connection, so keep it close and online for voice requests.

Calls and alerts on a 1.95-inch face

The IDW16 also makes and receives Bluetooth calls. Social media, email and SMS alerts show on the 1.95-inch HD screen, which reaches up to 500 nits for outdoor reading. You can read notifications but not reply to them, so answer longer messages on the phone after the session.

Faces come from a library of 100 cloud designs, and you can upload a selfie or a photo of your pet as the background.

There is one rule to know: the watch needs more than three hours of sleep before it records a night. Short naps will not show, and wearing it loosely can break the count. TOOBUR recommends long-term, steady wear, and that is good advice for any sleep tracker.

A simple sleep habit with the IDW16:

1. Wear it snug on the wrist every night for two weeks.
2. Keep a consistent bedtime, within half an hour each night.
3. Each morning, check total sleep and the share of deep and REM.
4. Look at the weekly view on Sunday and pick one change, such as no screens for 30 minutes before bed.

Heart rate, stress and the daytime numbers

Real-time heart rate runs through the day, and the watch can alert you when a reading looks abnormal. A stress reading sits next to it, useful for spotting the afternoons that drain you most.

With 100 sport modes, the IDW16 logs steps, calories, distance and speed for each session. Treat the figures as a record of effort and consistency rather than lab data:

• steps and distance are estimated from wrist motion
• calories are calculated from your profile and heart rate
• speed and distance improve when the phone is carried on outdoor sessions

For more on reading these numbers, see the notes on sleep and heart-rate accuracy.

1. Charge the watch fully; it takes about 2.5 hours.
2. Install VeryFit from your phone's app store and create an account.
3. Turn on Bluetooth and add the IDW16 from inside the app.
4. Accept the second Bluetooth request so calls route to the watch.
5. Open the Alexa section in VeryFit and sign in to link your account.
6. Choose which apps send alerts, then set a step goal.

Getting the most from the battery

The IDW16 is one of the longer-running watches in its group. TOOBUR rates it for:

• 7 to 10 days of daily use
• about 20 days in power-saving mode
• up to 30 days on standby

Power-saving mode is worth knowing about for travel. Switch it on for a long weekend away from a charger, and TOOBUR rates the battery for about 20 days, well past the usual week.

Alexa, calls and all-day heart rate draw more power, so heavy users should expect the shorter end. A weekly charge still keeps you well clear of a flat battery, and the charging and battery guide covers tired cables and dirty contacts.

If the phone drops the watch overnight, the stay-connected walkthrough covers background settings on Android and iPhone.

The Yoever IDW20 adds blood oxygen, a rotating crown and a 350mAh battery. The ID208 Plus is the one to consider for water: its 3ATM rating goes beyond IP68 splash protection. The IDW25 shares VeryFit and runs on Bluetooth 5.3.

Weight is another quiet advantage. At about 40g with a soft silicone strap, the IDW16 is light enough to forget overnight, which matters because a sleep tracker only works when it stays on. Pair that with the long battery and you get fewer gaps in the history: fewer nights missed, fewer days where the watch sat on a charger instead of counting steps. Over a month, those gaps decide whether the weekly charts show a real trend.

Pick the IDW16 when:

• you want the biggest face among these Alexa watches
• REM sleep in the nightly report matters to you
• long gaps between charges suit your routine

Check these points first:

• It comes in pink with a 22mm silicone strap, so any 22mm quick-release band fits; see the strap size guide.
• There is no built-in GPS.
• You cannot reply to messages from the watch.
• Blood oxygen is not among its listed readings.

For a non-Alexa calling watch with a similar screen, the Qecnato S68 offers a curved 1.95-inch face. If voice control is what gets you moving, the IDW16 keeps it one sentence away.
