A trial period lets a customer try your watch face for free for a limited time. If your watch face includes features that are hard to describe in words or convey in a screenshot or YouTube video, a trial period is a great way to have a customer experience your watch face first hand.
Trial periods use Samsung In-App Purchase (IAP). IAP is a payment service that makes it possible to sell items in Galaxy Store and is seamlessly integrated into Galaxy Watch Studio (GWS). That is, just like designing a watch face with GWS, setting up a trial period in GWS does not require you to learn the code needed to implement this feature.
After you have completed your watch face design, add a trial period in GWS and, optionally, test it.
In order to use trial periods in your watch face, the following requirements must be met:
You must have a commercial seller account in Seller Portal (see the Commercial Seller Request Guide for more information)
Your customer must be able to purchase watch face apps from Galaxy Store
Your customer can only download your watch face (which includes a trial period) to a Samsung watch running Tizen 22.214.171.124 or higher (see Compatibility for a list of compatible devices)
Trial periods cannot be used with weather text components such as Weather Type, Temperature, Humidity, City Name (Weather), and Last Update Time (Weather).
About distributing your watch faces with a trial period
As a seller, a key metric is to measure and maximize the conversion from free trial period to purchase. However, the most common business model for app purchases for Galaxy Watch in 2019 was the paid app model—without a trial period. In the majority of cases, the consumer assesses the paid app based on the screenshots and consumer reviews in Galaxy Store, buys it and then sees the app on the watch. The try-and-buy model allows the user to test the app risk-free on the watch for a trial period before buying it.
Because trial periods are configured using IAP, take the following into consideration:
Typically, an in-app purchase is used to provide additional features and functionality that may be purchased for an app. In this case, the in-app purchase is used to purchase the app (your watch face). Galaxy Store may list your watch face as an “In-App Purchase” item. This categorization may be confusing to the consumer.
When using a trial period, you must set the price of your watch face to free (in Seller Portal). If you do not prominently display that your watch face has a trial period, a customer may feel as if they have been misled after downloading your watch face. Be sure to include wording in the app title about the trial period (for example, “Try and Buy”).
When configuring IAP settings in GWS, you can choose to limit the consumer to one installation of your watch face, forcing the customer to purchase your watch face to continue using it; or reset the trial period when the watch face is re-installed, allowing the customer to re-install your watch face continuously and use it for free.
Add a trial period
To add a trial period to your watch face, you’ll need to:
Set the in-app purchase settings for your watch face in GWS.
Select a test mode when you build your project in GWS.
Configure in-app purchase when you register your watch face in Seller Portal.
Set in-app purchase settings in GWS
After you have finished designing your watch face, set the options for the trial period:
Launch GWS and open your watch face project.
Click the In-App Purchase Settings icon in the toolbar () or select Project > In App Purchase Settings.
Enter the following information in the In App Purchase Settings window:
Field Name Description Enable in App Purchase Select to enable a trial period for your watch face. Option Select the action that occurs when a customer re-installs your watch face configured with a trial period. This option is ignored when testing your watch face.
- Once trial is expired, unable to reuse app – When the trial period is over, the customer cannot re-install your watch face nor restart the trial period. That is, once the trial period is over, the customer must purchase your watch face to continue to use it.
- Trial is reset when app is re-installed – The customer can re-install your watch face and restart the trial period. That is, the customer can re-install your watch face continuously and use it for free.
Free for The length of time of the trial period. The time must be at least 1 minute and at most 999 days, 23 hours, and 59 minutes.
A field cannot be blank or empty. That is, you must enter a value, even if it is 0 (zero).Note :
If you enter a value for minutes that is greater than 59, each multiple of 60 in the value is added to the hour value. For example, if you enter 0 days, 1 hour, and 99 minutes, the period will be automatically set to 0 days, 2 hours, and 39 minutes. Likewise, if you enter a value for hours that is greater than 23, each multiple of 24 in the value is added to the day value. If the day value is set to 999 and the hour value is greater than 23, the day value resets to 100.
<div class="alert alert-success" role="alert"><strong>Tip</strong> : <p>If you will be testing the trial period, set the time to 1 minute to have the trial period expire quickly.</p>
</td></tr><tr><td>Item ID</td><td><p>An ID you create that is made up of letters, numbers, or some special characters (such as . - \ _ ).

However, you will only be using one in-app item ID when setting a trial period for your watch face.</p></td></tr></tbody></table>
- Click OK.
Build your project
Before you can register your watch face in Seller Portal, you must build your project in GWS:
In GWS, click the Build icon in the toolbar (), F10, or select Project > Build.
In the Build Project window, set the IAP Test Mode:
Commercial – You are ready to sell your watch face in Galaxy Store. If the customer purchases your watch face after the trial period ends, the customer is charged for this purchase.

After testing, when you are ready to sell your watch face, in GWS, you must reset the IAP Test Mode to Commercial and re-build your project. Then, in Seller Portal, replace the binary with this re-built project file and complete all the required fields before submitting your watch face for validation and distribution.
Track downloads and purchases
If you want to compare the number of downloads of your watch face to the number of in-app items purchased (the purchase of your watch face after the trial period has expired), use Seller Portal statistics.
- Log in to Seller Portal and click Statistics. The Galaxy Store Statistics System opens in another page.
- From the Galaxy Store Statistics System, go to Applications.
- In the upper right corner, there is a date range. Click on it and then set the Date Range Selection to the period of time in which you want to track your app.
- Scroll to the bottom of the page. Above the list of apps, select the New Downloads filter then locate your watch face to determine the number of downloads during the date range you selected.
- Select the Item Purchases filter then locate your watch face to determine the number of purchases made of your watch face.
Remember how long you set your trial period. You will not see any sales of your watch face for that length of time after your watch face first appears for sale in Galaxy Store.
