Merchants will be able to use your POS SDK apps
Tools
Effective July 19, 2018
On July 19, 2018, Shopify will be releasing v2.5 POS Android and v4.8 POS iOS, which means that all merchants will be able to view your POS apps on their iOS and Android phones and tablets. Make sure to test the design and functionality of your POS apps on iOS and Android phones and tablets prior to the public release of v2.5 POS Android and v4.8 POS iOS.
After v2.5 Android POS and v4.8 iOS POS are released, you won't be able to see your apps on POS until you upgrade. Previous versions (v4.7.X and v2.4.X) will no longer show apps.
