You want something small that tracks your sleep and steps without a watch on your wrist. Then you find out the ring costs a lot up front, and the app wants a monthly fee on top before it shows you much.

Plenty of rings now skip the fee. But "no subscription" can mean only the basics are free, some rings need a charge every few days, and most use their own sizes, so guessing your normal ring size can mean a return.

We compared five smart rings sold with no monthly fee. One says every feature in its app is free, lists up to 14 days per charge, comes with a charging case and is the only one here that can buzz on your finger.

1. Nothing behind a paywall

The RingConn Gen 3 listing says all its features are in the app with no subscription, not just a "standard" set.

2. Two weeks per charge

It lists up to 14 days per charge, and the charging case in the box tops it up when you put it away.

3. It can tap you

It's the only ring here with vibration alerts, so inactivity and low-battery reminders reach you without checking your phone.

What to look for in smart ring without subscription

Read what "no subscription" covers

Some rings make every feature free. Others say only "standard" features are free. Look for wording like "all features" or "full access" on the listing.

Size it first

Most smart rings use their own sizes, not jewelry sizes. Wear the maker's sizing kit for a day and a night before you order. See our smart ring sizing guide.

Compare battery days, and the box

Stated battery runs from 2 to 14 days here. A charging case lets you top up the ring without a cable when you take it off.

Check your phone

All five here list iPhone and Android support. Some well-known rings work only with Android phones, so check before you buy.

Questions about smart ring without subscription

What are the best smart rings without a subscription?

Of the five we compared, the RingConn Gen 3 says every app feature is free, lists up to 14 days per charge and adds vibration alerts. The RingConn Gen 2 is close behind with a charging case and 10 to 12 days per charge.

Is there a best smart ring for men or for women?

The rings are the same for everyone. Pick by size, finish and thickness. The Gen 3 comes in sizes 6 to 15, and several of these rings show cycle tracking in their apps, per their listings.

Which smart ring is best for sleep tracking?

All five track sleep, per their listings. A ring with long battery life, like the RingConn Gen 3, needs fewer nights off the finger for charging. These are wellness gadgets, not medical devices; RingConn says so on its own site. See a doctor for any health concern.

What about Oura or the Samsung Galaxy Ring?

Oura is the best-known smart ring, but it pairs the ring with a paid membership for its full app features. If you want no monthly fee, the rings on this page say they don't need one. Samsung's Galaxy Ring also says it needs no app subscription, but its listing says it works with Android phones only and lists up to 7 days per charge, against up to 14 days for the RingConn Gen 3.

Bottom line: the best smart ring without subscription

For a smart ring with no monthly fee, the RingConn Gen 3 is the one to get: every app feature is free, it lists up to 14 days per charge with a charging case, and it can vibrate on your finger. Choose the RingConn Gen 2 for a charging case that lasts weeks on trips, the Gen 2 Air for a thin everyday ring, the Amazfit Helio for workout stats like VO2 Max, and the BIEMHA if you just want the basics for less.
