# Liminal vs Corpus

The clearest difference is ads: Liminal at none against Corpus's shown. Liminal also leads on ratings volume (5 vs 1). Corpus's advantage is update cadence (every 2 days vs every 2 weeks) and rating (5.0 vs 4.8). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Liminal sells 1 one-off in-app purchase and Corpus sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

Corpus holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Liminal has 5 ratings behind it against 1, so its average is the more settled of the two.

Liminal ships an update every 2 weeks, Corpus every 2 days. Both last shipped on October 25, 2026.
