# Codebook vs T2S

The clearest difference is review sentiment: Codebook at 100% against T2S's 49%. Codebook also leads on rating (5.0 vs 3.3) and update cadence (every 3 days vs every 2 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Codebook sells 20 in-app purchases, starting at $2.99 per 7 days and T2S sells 7 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Codebook holds the better App Store score, 5.0 against 3.3. Both are backed by a comparable volume of ratings — 31 and 55 respectively. Written reviews point the same way: 100% of Codebook's written reviews are positive against 49% of T2S's.

Codebook ships an update every 3 days, T2S every 2 weeks. The most recent releases landed on October 5, 2026 and October 7, 2026 respectively.
