In this guide 7 sections
The wearable shelf has three different products that look similar in a listing: calling smartwatches with big screens, slim fitness bands, and the newer smart rings. They are not interchangeable. This guide sets out what each does well and the questions to ask yourself before choosing.
What a budget calling smartwatch does
Watches like the Joyroom FC2 and COLMI P78 connect to your phone over Bluetooth and let you answer and make calls from the wrist with a built-in speaker and microphone, show notifications, track steps, heart rate and sleep, and run for several days per charge. They do not run apps the way an Apple Watch does, and the health readings are indicative rather than medical.
What a fitness band does better
A band is thinner, lighter and lasts one to two weeks on a charge. It tracks the same basics without a speaker. If you want something you forget you are wearing — especially for sleep tracking — a band wins. If you want to glance at WhatsApp messages or take a call while riding, a watch wins.
The smart ring option
Rings such as the COLMI R12 track sleep, heart rate and steps with nothing on the wrist, and some add a small display. They suit people who do not like watches or who already wear a mechanical one. Ring size matters: measure a ring you already own against the listing's sizes.
Five questions before you buy
- Do you want to take calls on it? Then it must say "Bluetooth calling" — a watch that only shows the caller's name is not the same thing.
- iPhone or Android? All of these pair with both, but some features (quick replies, some watch faces) are Android-only. Check the listing.
- How often will you charge it? Always-on display halves battery life. If charging every two days annoys you, turn it off or pick a band.
- Do you swim or sweat heavily? Look for IP68 or 5ATM. "Water resistant" without a rating means rain only.
- Wrist size? Big round calling watches sit awkwardly on small wrists; the listing's case size in millimetres tells you more than the photos.
Setting it up properly
Pair through the maker's app (named on the listing), not the phone's Bluetooth menu, or notifications and calls will not come through. On Android, allow the app to run in the background and exempt it from battery optimisation, otherwise messages stop arriving an hour after you put the phone down. Set your height, weight and wrist in the app on the first day: step length and calorie figures depend on them. Raise-to-wake plus a five-second screen timeout gives the best balance of convenience and battery.
Accuracy, honestly
Step counts and heart rate on budget wearables are good enough to see trends — more steps this week than last, a resting heart rate that is drifting. Blood oxygen and blood pressure readings on any wrist device are not a substitute for a proper monitor; if that is what you need, the health & wellness shelf has upper-arm monitors.
Our picks by priority
- Calls first, with a long battery — QCY Watch GS.
- Calls first, bigger screen and metal strap options — COLMI P78 / Joyroom FC2.
- Smallest budget for a calling watch — COLMI P71.
- Nothing on the wrist — COLMI R12 smart ring.
Everything on the smartwatches & wearables shelf ships cash on delivery; pair through the maker's app named on the listing rather than the phone's Bluetooth menu.
Frequently asked questions
Can a budget smartwatch make calls?
Yes, if the listing says Bluetooth calling — it uses your phone's connection and a built-in speaker and mic. The watch has no SIM of its own.
Do these smartwatches work with iPhone?
Yes, through the maker's app. Some extras such as quick replies are Android-only, so check the listing.
How accurate is heart rate on a cheap smartwatch?
Good enough for trends at rest and during steady exercise; less reliable during intervals. Blood oxygen and pressure readings are indicative only.
Smartwatch or fitness band for sleep tracking?
A band, because it is lighter and lasts longer between charges, so you actually wear it to bed.
