# Multi vs SkyDuo

The clearest difference is rating: SkyDuo at 4.7 against Multi's 2.8. SkyDuo also leads on ratings volume (2K vs 13) and review sentiment (78% vs 60%). Multi's advantage is in-app purchases (none vs 11). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. SkyDuo sells 11 in-app purchases, starting at $2.99 per 7 days. Multi asks for nothing beyond the download.

SkyDuo holds the better App Store score, 4.7 against 2.8.
