Verdict
The clearest difference is review sentiment: Sign at 100% against LedArt's 19%. Sign also leads on rating (5.0 vs 2.5) and iOS requirement (8.0 vs 13.0). LedArt's advantage is in-app purchases (none vs 1) and update cadence (every 2 months vs every 4 months). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Sign sells 1 one-off in-app purchase. LedArt asks for nothing beyond the download.
Sign holds the better App Store score, 5.0 against 2.5. That said, the two scores are not equally well evidenced: LedArt has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of Sign's written reviews are positive against 19% of LedArt's.
Sign ships an update every 4 months, LedArt every 2 months. Both last shipped on November 2, 2026.
