# Otis Presentation Maker vs Slides

The clearest difference is review sentiment: Otis Presentation Maker at 100% against Slides's 67%. Otis Presentation Maker also leads on rating (5.0 vs 4.7) and update cadence (every 11 days vs every 6 weeks). Slides's advantage is monetization model (free vs freemium) and ratings volume (25 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Otis Presentation Maker sells 2 in-app purchases, starting at $6.99 per month and Slides sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Otis Presentation Maker holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Slides has 25 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Otis Presentation Maker's written reviews are positive against 67% of Slides's.

Otis Presentation Maker ships an update every 11 days, Slides every 6 weeks. The most recent releases landed on September 18, 2026 and September 9, 2026 respectively.
