To make it easier to evaluate the taximeter app we decided to make it free, but limit it to only 5 taxi trips. By upgrading, you will remove this limitation and will be able to create unlimited amount of trips.
From version of 1.7 of the app, this one-off in-app purchase also includes integration with Square Point Of Sale app for payments and mobile printing.
If you used to have the paid version of taximeter app, please just use "Restore purchases" button in the upgrade reminder screen or "Restore" button in the upgrade buying screen to restore either your former upgrade or purchase of the paid app version.
Thank you for using the taximeter app and we are working constantly on adding more features!
