Subscriptions are handled a little differently on iOS and Android. If you are an iOS user, subscription changes will take effect after your current subscription term expires. For example, if you are on a monthly subscription and want to upgrade to yearly, if you do that mid-way through the month, it will change over and charge you the full yearly subscription price at the end of the month. Then, your subscription will renew every year instead of every month. Both charges and time are not prorated on iOS. If you downgrade or cancel your subscription, it will not go into effect until your current subscription term expires.
If you upgrade your subscriptions, it will change immediately and the remaining time will be prorated. Unfortunately, the subscription charge cannot be not prorated. For example, if you are on a monthly subscription and want to upgrade to yearly after 7 days, it will instantly switch your subscription over to yearly but it won’t charge you until the cost value in time is used up first. Here is a more in depth example from the Google Play Store to explain it further:
Samwise has a subscription to online content from the Country Gardener app. He currently has a monthly subscription to the Tier 1 version of the content, which is text-only. This subscription costs him $2 per month, and it renews on the first of the month.On April 15, Samwise chose to upgrade to the annual version of the Tier 2 subscription, which includes video updates and costs $36 per year. Samwise’s Tier 1 subscription ends immediately. Since he paid for a full month (April 1-30) but upgraded halfway through the subscription period, half of a month’s subscription ($1) is applied to his new subscription. However, since that new subscription costs $36 per year, the $1 credit balance pays for only 10 days (April 16-25), so on April 26, he is charged $36 for a new subscription and another $36 on April 26th of each year following.
Both iOS and Android
We are very limited in the information each store provides us and our capabilities. If you have any issues with billing, it’s best to direct those to the individual app stores.
