This app allows users to read or write 4 different types of documents, journals, stories, quotes and poems through a rich text editor. Each section is divided by language so that each user can use the language they prefer or improve the idiom they are studying. There is a profile page where you can link your social networks, view your followers or users we follow and read comments other users may have left on our profile. There is a trophy system, specifically each day, week and month the documents that have received the most likes for each language and type of document will be chosen. To avoid problems in using the app there is a tutorial section where the main features are described in detail and it is also possible to send a direct message to the developer so that he can correct any problems.

Verdict
The clearest difference is in-app purchases: Poetrify at none against Infinite Library's 4. Poetrify also leads on iOS requirement (13.0 vs 17.0). Infinite Library's advantage is rating (4.9 vs 4.5) and ratings volume (41 vs 6). On price, review sentiment, update cadence and ads there is nothing between them.

Infinite Library holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Infinite Library has 41 ratings behind it against 6, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Poetrify ships an update every 2 weeks, Infinite Library every 6 days. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
