Verdict
The clearest difference is review sentiment: Project Iris at 100% against Search Ace's 60%. Project Iris also leads on rating (5.0 vs 4.6) and monetization model (free vs free with in-app purchases). Search Ace's advantage is ratings volume (605 vs 14). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Search Ace sells 6 in-app purchases, starting at $2.99 per month and Project Iris sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Project Iris holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Search Ace has 605 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 60% of Search Ace's written reviews are positive against 100% of Project Iris's.
Search Ace ships an update every 3 weeks, Project Iris weekly. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
