Other Common Questions

These messages are shown because you are using a paid app or clockface of which the trial has expired.
If you do not want to pay for the app or clockface, remove the app, or install another clockface from the appstore, and the messages will automatically stop.

How to remove an app on a Fitbit smartwatch:
How to change clockface on a Fitbit smartwatch:

All clockfaces and apps clearly mention in their description if they are paid or not, so it should not be hard to find a free one instead.

How to recognize a paid app or clockface on Fitbit:
All the apps and clockfaces sold with KiezelPay are one time payments for a lifetime license.

However, because we cannot always recognize you again after you remove and reinstall an app or clockface, it might ask for payment again if you ever remove and reinstall it.

When that happens you can unlock it again for free by going to
When you install an app or clockface you can choose certain permissions; one of those is the "internet" permission. It cannot work without that permission.

For an app or clockface that doesn't have it, the easiest way to fix this is to install another clockface first, then install the one you want again. As soon as you install it, a small screen will pop up which lets you choose all permissions you grant to this clockface, it's best to allow them all (but at least allow the internet permission).

After you re-installed, and the trial (if any) ends, it will ask you to pay again. You can then unlock it for free here.
Each code is valid for one hour. This probably means your code is expired.

For now, the solution is to make the clockface restart, which will force a new code to be loaded and displayed. On a Fitbit smartwatch, you can do this by swiping up to the today screen, then backing out of it again until you are in the clockface again.
On a Garmin smartwatch, shutdown and restart your watch.
This can have a few causes. It is possible you made a typo in your e-mail address when you purchased the app, so now our system cannot find your license.

Another possibility is that you are trying to unlock another clockface/app than the one you actually purchased.

Please double check that the name of the clockface/app you are trying to unlock is exactly the same as the name in the purchase success mail you got after purchasing (some names are confusingly similar unfortunately).

If you are very sure you have the correct app, please contact us at the bottom of the page with the following information:
  • send the PayPal InvoiceID, which you can find on the PayPal receipt you got after purchasing (it starts with REF).
  • If you paid with creditcard instead, send the first 6 and last 4 digits of your creditcard number (do not send the complete number!).
This will allow us to find your purchase and check why the unlock is not working.

Please also send along the purchase purchase code your watch tells you to enter. This allows us to check which app is asking for payment.
After your purchase, we sent you an e-mail containing more information about what you purchased.

If you purchased a bundle, the e-mail will show all clockfaces/apps in the bundle with a download button next to each one of them.
Use that download button to go to the appstore and install the clockface/app on your watch.

If you cannot find the e-mail any more, you can perform a lookup of all your purchases at

Note: These download links only work if you use them on the phone or tablet on which you have installed the Fitbit, Connect IQ (Garmin) or Pebble app!

If the download button does not take you to the appstore, this probably means the developer has not correctly configured the appstore link in his/her account. You can contact the developer and ask him/her to fix this, or you can use the search functionality in the appstore to find the app/clockface instead.
The exact extra cost depends on the price of the app being sold, but on average, it costs us an extra $0.30 to process credit card payments compared to PayPal. Our profit margins are not large enough to absorb this extra cost; on cheap apps we would even lose money for each purchase if we did that. Merchants can choose to charge the $0.30 extra fee to the customer, or absorb this fee themselves.

If you do not want to pay the $0.30 extra fee, use PayPal instead. It is possible to link your credit/debit card in the PayPal account as payment source.
Yes, but developers are not able to perform the refund themselves, so please contact the KiezelPay helpdesk at the bottom of the page if you want a refund.

We issue refunds for digital products within 30 days of the original purchase of the product. We recommend contacting us for assistance if you experience any issues. If you have any questions about our Returns and Refunds Policy, please contact us at the bottom of the page.
You first install the clockface or app you want from the gallery as usual.

The clockface/app will automatically show you the code when the trial ends (if it has any, otherwise it will show it immediately after installing). At that time you can use the code to purchase it at or unlock it at if you already paid for it before.

Until that happens you don't have to do anything.
We have made a special page where you can look up your complete purchase history here.
Unfortunately we are not always able to recognize you again after (re)installing an app or clockface, so our system may think you are a new customer when that happens, and may ask you to pay again.

Luckily you can unlock your clockface again for free here.

Just enter the code it is showing you and the e-mail address you used for the original purchase and you will be up and running again in no time.
We do not send you a purchase code in your email, and you do not need a code to switch to another clockface.

Instead, you first install the new clockface or app you want and then wait for it to ask you to pay again.

As soon as that happens you can unlock it again for free by going to using the code it shows you on the watch at that moment.

If for some reason it does not ask you to pay again, that isn't a problem and you can just use the clockface as is. The functionality is exactly the same before and after unlocking.


Developers work hard and we understand that, so why shouldn't you get paid for your hard work? We made KiezelPay easy to add, and easy to get the money that you deserve. It takes minutes to set up and to start collecting money.
Once the user downloads the app/face with KiezelPay integrated, the user's watch will then vibrate and present a purchase code. The code is entered at where they can purchase access to the app/clockface. Once purchased, the code screen disappears on the watch and they can continue to use the app/face as normal.
The best way to get started is to sign up for an account and visit our developer documentation page. Then just follow our easy step by step guide.
The first time for an average developer it takes about 30-60 minutes; after a few times you can do it in a matter of minutes.
This probably means you forgot to disable test mode in the app and other people are "purchasing" your app in test mode. To fix this, release an update of your app as soon as possible with test mode disabled. Everyone that "purchased" your app when test mode was enabled will see a new payment notification within 24 hours (as soon as the periodic recheck happens) and will have to pay for real this time to unlock the app again.
We support this with our "bundles" feature. You can simply create a new bundle on the products page in your account. When the customer installs one of your apps which is part of a bundle, he/she will get the choice to purchase the complete bundle, or only the single app.
Yes! We are always looking for new partnerships. Our server architecture and API are very generic and usable for any type of (IoT) device. As long as your device has internet access and is able to communicate a 5 or 6 digit number to your customers, it can support paid apps with KiezelPay. Contact us for more info.
There is no cost to start using KiezelPay. KiezelPay does, however, take a 27% fee for each purchase with a minimum of $0.27 USD.

* KiezelPay handles sales tax requirements. However handling the revenue you as developer will gain from KiezelPay as "income" and all tax requirements following from that in your country of residence is your own responsibility.
