# 슥삭 vs flex

The clearest difference is review sentiment: 슥삭 at 98% against flex's 28%. 슥삭 also leads on monetization model (ad-supported vs freemium). flex's advantage is rating (3.4 vs 3.0) and update cadence (every 3 days vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

flex holds the better App Store score, 3.4 against 3.0. That said, the two scores are not equally well evidenced: flex has 18 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 98% of 슥삭's written reviews are positive against 28% of flex's, so the app with the better star average is not the one people write more warmly about.

슥삭 ships an update every 3 weeks, flex every 3 days. The most recent releases landed on October 25, 2026 and October 27, 2026 respectively.
