Though it is not required, we recommend that you create a Tynker account and are logged in on the app before you purchase an iPad subscription. You will purchase the subscription from the settings within the free red Tynker app. Click on the Gear in the top left and you will see an "Upgrade" button in the top right. We currently have a 7 day free trial for our annual iPad subscription. Click "Start Your Free Trial Today" if you want to sign up for the annual plan. If you just want the monthly plan, select "Pricing" in the bottom left and select the monthly plan.
Note: The free trial will automatically switch to a paid subscription if you do not cancel it at least 24 hours before the trial ends. The iPad subscriptions will automatically renew until you cancel them through your iPad settings.
