# SBchat vs SkyDuo

The clearest difference is in-app purchases: SBchat at none against SkyDuo's 10. SBchat also leads on review sentiment (92% vs 78%). SkyDuo's advantage is ratings volume (2K vs 66) and iOS requirement (12.0 vs 15.1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. SkyDuo sells 10 in-app purchases, starting at $2.99 per 7 days. SBchat asks for nothing beyond the download.

SBchat holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: SkyDuo has 2K ratings behind it against 66, so its average is the more settled of the two. Written reviews point the same way: 92% of SBchat's written reviews are positive against 78% of SkyDuo's.

SBchat ships an update every 3 weeks, SkyDuo every 11 days. The most recent releases landed on November 3, 2026 and November 11, 2026 respectively.
