# UCHAD vs Invisible String

The clearest difference is rating: UCHAD at 4.7 against Invisible String's 3.6. UCHAD also leads on ratings volume (13K vs 5) and iOS requirement (15.0 vs 18.0). Invisible String's advantage is review sentiment (67% vs 48%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. UCHAD sells 18 in-app purchases, starting at $1.99 per 7 days and Invisible String sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

UCHAD holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: UCHAD has 13K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 48% of UCHAD's written reviews are positive against 67% of Invisible String's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
