# Chat Memo vs tetrify

The clearest difference is rating: tetrify at 4.8 against Chat Memo's 4.3. tetrify also leads on ratings volume (58 vs 9) and iOS requirement (13.0 vs 15.0). Chat Memo's advantage is in-app purchases (none vs 5) and review sentiment (100% vs 86%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. tetrify sells 4 in-app purchases, starting at $1.99 per month. Chat Memo asks for nothing beyond the download.

tetrify holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: tetrify has 58 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of Chat Memo's written reviews are positive against 86% of tetrify's, so the app with the better star average is not the one people write more warmly about.

Chat Memo ships an update weekly, tetrify every 5 days. The most recent releases landed on October 9, 2026 and October 10, 2026 respectively.
