# 默信 vs 泡泡

The clearest difference is rating: 默信 at 2.4 against 泡泡's 1.0. 默信 also leads on ratings volume (5 vs 1). 泡泡's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. 默信 sells 10 one-off in-app purchases. 泡泡 asks for nothing beyond the download.

默信 holds the better App Store score, 2.4 against 1.0. That said, the two scores are not equally well evidenced: 默信 has 5 ratings behind it against 1, so its average is the more settled of the two.

默信 ships an update fortnightly, 泡泡 every 3 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
