# I vs CellNotes

The clearest difference is ads: CellNotes at none against I's shown. CellNotes also leads on update cadence (every 3 weeks vs every 6 months). I's advantage is iOS requirement (12.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

I ships an update every 6 months, CellNotes every 3 weeks. The most recent releases landed on September 27, 2026 and September 6, 2026 respectively.
