We offer 2 in-app purchases: verb tenses and prepositional pronoun details. Here’s how they work.
When you first download Greann Gaeilge and tap Verb Conjugation and then tap the Select button, you see only 2 verb tenses listed: present habitual and future (for the verb bí, you’ll also see the present tense listed). These come free with the app.
If you make the Verb Tenses upgrade, you’ll now have access to the past and conditional tenses. They’ll just magically appear when you tap Verb Conjugation and the Select button.
Prepositional Pronoun Details
When you first download the app, and tap Prepositional Pronouns, you see a list of all the prepositions and how they are modified.
If you make the Prepositional Pronoun Details upgrade, you’ll now have access to more details. On the iPhone and iPod touch, this will be text that appears under the pronouns. On the iPad, you’ll see a new “info” button (a green lowercase “i” in a white circle) next to each preposition—just tap this button for more information.
I hope this makes the in-app purchase clearer.
