# Human Codex vs ShiftNight

The clearest difference is monetization model: Human Codex at freemium against ShiftNight's subscription. ShiftNight's advantage is ads (none vs shown) and ratings volume (54 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Human Codex sells 2 in-app purchases, starting at $12.99 per month and ShiftNight sells 11 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Human Codex against 4.9 for ShiftNight. That said, the two scores are not equally well evidenced: ShiftNight has 54 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Human Codex ships an update every 3 days, ShiftNight every 5 days. The most recent releases landed on October 7, 2026 and October 11, 2026 respectively.
