Verdict
The clearest difference is ads: EXTENSION.app at none against Split Screen's shown. EXTENSION.app also leads on review sentiment (78% vs 43%) and update cadence (every 5 weeks vs every 6 months). Split Screen's advantage is iOS requirement (15.0 vs 26.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Split Screen sells 2 in-app purchases, starting at $1.99 per 7 days and EXTENSION.app sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
EXTENSION.app holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: EXTENSION.app has 4.9K ratings behind it against 482, so its average is the more settled of the two. Written reviews point the same way: 43% of Split Screen's written reviews are positive against 78% of EXTENSION.app's.
Split Screen ships an update every 6 months, EXTENSION.app every 5 weeks. Both last shipped on October 7, 2026.
