Full Version and In-App Purchases
Free Basic Version
SongBook+ can be downloaded from the Apple App Store without charge and is free to use in its basic version for hobby musicians.
The basic version already includes all features of the full version, but is limited to 1 book with 15 songs. If you want to remove this limitation, you can unlock the full version with an in-app purchase.
Unlocking the Full Version
In the full version, the number of songs is unlimited and you can also create and use 15 books. In addition, you can create any number of data subdirectories with completely separate data and settings (multi-client capability).
You can unlock the full version with a monthly or yearly automatically renewing subscription or through a one-time payment.

Press here to open the menu.
Select "Unlock Full Version".

Press here for a monthly subscription
Press here for a yearly subscription
Press here to purchase the full version (including 5 years of free updates)
Prices depend on the buyer’s country, currency, and exchange rate. They are determined by Apple and displayed below the key.
Full Version as a Subscription
The subscription renews automatically unless renewal is turned off at least 24 hours before the end of the current period. The Apple user account will be charged for renewal during the 24 hours before the end of the current period. Subscriptions can be managed by the user and automatic renewal can be turned off in the settings of the iTunes user account.
Purchase the Full Version (including 5 years of free updates)
The one-time payment entitles you to use the full version indefinitely. However, after 5 years, you may not install updates, otherwise the full version will expire upon update. SongBook+ will remind you beforehand so you can disable automatic app updates. Thus, you can continue to use the full version without additional payment indefinitely even after 5 years.
Switch from Subscription to Purchased Full Version
If you have already signed up for a subscription to the full version, but now would prefer to switch to the purchased full version, you can do the following:
Cancel the SongBook+ full version subscription in your Apple account
The subscription remains valid until the already paid period has expired
When you open SongBook+ a few days after the subscription has expired, it will be downgraded to the demo version.
SongBook+ will then display a hint instead of your songs that there are too many songs in the database for the full version. Your songs are still in the database but are not displayed because there are too many.
Now you can unlock the full version again normally through an in-app purchase. You have the option again to choose between a monthly or annual subscription or the purchased full version.
Sponsorship
If you have purchased the full version (not a subscription) and would also like to voluntarily support its development and support, there is an option for sponsorship.

Sponsorship is voluntary and does not offer any added value in the first 5 years of the full version. However, after these 5 years, it continues to entitle you to updates and use of the full version as long as the sponsorship is not canceled.
