# SKIIID vs isxynth

The clearest difference is rating: SKIIID at 4.4 against isxynth's 3.7. SKIIID also leads on update cadence (every 4 days vs every 34 months) and price ($3.99 vs $7.99). isxynth's advantage is review sentiment (100% vs 74%) and iOS requirement (11.0 vs 16.0). On ads, in-app purchases, monetization model and device support there is nothing between them.

SKIIID costs $3.99 and isxynth $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

SKIIID holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: SKIIID has 31 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 74% of SKIIID'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.

SKIIID ships an update every 4 days, isxynth every 34 months. The most recent releases landed on September 26, 2026 and September 28, 2026 respectively.
