Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings
