# apeDelay vs isxynth

The clearest difference is rating: apeDelay at 4.6 against isxynth's 3.7. apeDelay also leads on update cadence (every 4 months vs every 34 months) and ratings volume (17 vs 3). isxynth's advantage is review sentiment (100% vs 88%) and iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

apeDelay costs $7.99 and isxynth $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

apeDelay holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: apeDelay has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 88% of apeDelay's written reviews are positive against 100% of isxynth's, so the app with the better star average is not the one people write more warmly about.

apeDelay ships an update every 4 months, isxynth every 34 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
