# Codebook vs Tread

The clearest difference is ads: Tread at none against Codebook's shown. Tread also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.4 vs 15.6). Codebook's advantage is rating (5.0 vs 4.5) and ratings volume (31 vs 10). On price, review sentiment, update cadence 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 Tread sells 1 in-app purchase, starting at $2.99 per year. Whichever you choose, the download price is not the number that matters.

Codebook holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 31 and 10 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

Codebook ships an update every 3 days, Tread every 4 days. The most recent releases landed on September 27, 2026 and September 10, 2026 respectively.
