Sell Your Used Fitness Tracker — 0% Fees

A used fitness tracker typically sells for £15 to £90, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Fitness trackers sell on battery life and whether the strap is standard or proprietary, and both are worth stating before a buyer asks.

The short version

Typical range: £15 – £90 — see the full fitness tracker value guide
What decides your price: condition, and how well you evidence it in photographs
Cost to sell here: nothing, at any price
Category: Electronics

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Charge fully and time a realistic period of use with the features you actually run.
Unpair from your phone, remove it from any account, and factory reset it.
Note the strap width and whether it takes standard bands or a proprietary fitting.

The photographs that sell a fitness tracker

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

The tracker with the display on
The rear sensor array and charging contacts
The strap and its attachment mechanism
The proprietary charger, plus any scratch on the screen

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Brand, model and strap: “Fitbit Charge 5, Small Strap, Charger Included”. Model is the search. Say whether the charger is included — almost all are proprietary and a missing one is an expensive nuisance.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Brand, model and strap size
Tested battery life in days with normal use
Whether the strap is standard width or proprietary
Whether the charger is included, and screen condition

What buyers will actually ask

You will receive the same three messages about a fitness tracker. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“How many days does the battery last?”

Time it with your normal settings and give the figure. Tracker batteries degrade and an honest number sets the right expectation.

“Is the charger included?”

Confirm. Fitness tracker chargers are almost always proprietary and often discontinued for older models.

“Can I use my own strap?”

Measure the fitting and say whether it takes standard bands. Proprietary strap systems limit the buyer’s options.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The fitness tracker value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £52 sale — roughly the middle of the range for a fitness tracker — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£52
Poshmark	−£10	£42
eBay	−£7	£45
Mercari	−£5	£47
Etsy	−£3	£49

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

Strong January lift with resolutions, and a Christmas peak. Recent models sell within days.

Tiny and cheap to post. Include the charger and photograph exactly what goes into the parcel.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

What is a used fitness tracker worth?

Typically £15 to £90 depending on brand, model and battery condition. See the fitness tracker value guide.

Do I need to unpair it first?

Yes. Unpair from your phone, remove it from your account and factory reset, or the buyer cannot set it up with their own.

Does a missing charger matter?

A great deal. Most tracker chargers are proprietary and older models are often discontinued, so a missing charger can make the device effectively unusable. Say clearly either way.
