Our verdict on each
Kospet
Kospet sells smartwatches outright rather than through a subscription, which suits anyone tired of recurring fees: the membership costs $0 and watches start at $59.99. Nothing recurs after the first purchase, so the outlay you weigh at entry is the outlay you pay.
Polar
Polar suits anyone who wants a chest strap grade training setup from a maker trading since 1977. The trade off sits at entry and at the charger: €179.90 for the cheapest device and 10 days of battery both land mid table here, so the pull is the sensor set.

Pros and cons
Kospet
Pros
- The membership costs $0, so there is no recurring line to cancel once the purchase is done.
- Kospet sits at position 1 of 21 on membership cost, which is the measure that separates it from rivals.
- Sensors cover heart rate, spo2 and hrv and the app runs on iOS and Android, so the phone you already own is not a barrier.
Cons
- A lifetime warranty is not offered and cover runs 1 year, so a late failure is a cost you carry.
- The entry price of $59.99 is above Oukitel at $34.99, so buyers on a tight budget pay more for the extras.
- Kospet lists smartwatch only, where Amazfit spans smartwatch, fitness tracker and smart ring, so a tracker or a ring means shopping elsewhere.
Polar
Pros
- Sensors cover heart rate, spo2 and ecg, a wider reading set than heart rate and step count alone.
- Water resistance of 50 metres handles pool and open water without a strap change.
- Warranty of 2 years runs longer than the 1 year median for smartwatches and fitness trackers.
Cons
- Entry price of €179.90 sits above the €99.90 median entry price in this category, so the first buy is dearer than most of this list.
- Battery life of 10 days is shorter than the 11.5 day median for smartwatches and fitness trackers.
- Support runs through help centre, so questions about a specific device go through written material rather than a direct line.
Who each suits

Polar
Who it suits
- Swimmers and open water athletes, given water resistance of 50 metres.

Questions about each
Kospet
What does a Kospet smartwatch cost?+
Kospet smartwatches start at $59.99. That is the entry price for the line rather than a first order discount, and it is a hardware price paid once. With the membership costing $0, the figure is the full amount you commit on the day you order.
Is there a monthly subscription or membership fee?+
The membership costs $0 a month, so there is no recurring charge to set up or cancel. Kospet sits at position 1 of 21 on that measure among the brands compared. Nothing renews after the watch is bought, which is the clearest split between Kospet and subscription services.
Polar
What does the cheapest Polar device cost?+
Polar's entry device is priced at €179.90, which sits above the €99.90 median entry price across smartwatches and fitness trackers. On the ranking used here, Polar is placed 24 of 31 brands on entry price, so buyers pay toward the higher end of the field.
Is there a monthly membership fee?+
Polar's membership is free, listed at €0 a month, so the hardware is the only recurring cost and there is nothing to cancel each year. That sits alongside entry pricing of €179.90 for the cheapest device rather than being bundled into it, which keeps the long term cost predictable.
