Verdict
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.
