# Zeno vs StudyNotes AI

The clearest difference is ads: StudyNotes AI at none against Zeno's shown. Zeno's advantage is update cadence (every 4 days vs fortnightly) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Zeno sells 2 in-app purchases, starting at $12.99 per month and StudyNotes AI sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Zeno ships an update every 4 days, StudyNotes AI fortnightly. The most recent releases landed on September 24, 2026 and September 9, 2026 respectively.
