Please note that the free version is intended to provide users a preview of the functions of the app. It has a limited number of cost sheets and entries (5 cost sheets and 20 entries in a cost sheet), no synchronization feature (via Dropbox) for joint budget management. To remove all restrictions, please upgrade to the full version with a one-time purchase or buy a subscription (monthly or annual).
