Truebill uses advanced algorithms to analyze your transactions and automatically identify your subscriptions and bills.
If you are missing subscriptions, first make sure that you have linked the account that you pay the subscription with to Truebill. Also, check the "Inactive" link (at the bottom of your Recurring tab in the app) to see if the subscription is listed there.
If you still cannot find your subscription, you can add it manually as well. Simply open the Truebill mobile app, go to the "Recurring" tab, and click the "+" icon in the upper right. This will allow you to add your bill manually.
Note: Due to the way iTunes and Google Play bundle subscriptions, we are unable to display subscriptions purchased through iTunes. You can also add those manually if you like. For more information, see this help article: Where can I see my Apple iTunes subscriptions?
