Verdict

The call

The clearest difference is ads: Mantis Bible Study at none against TSK Bible Commentary's shown. Mantis Bible Study also leads on update cadence (every 2 days vs every 6 months) and ratings volume (299 vs 3). TSK Bible Commentary's advantage is rating (3.3 vs 3.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mantis Bible Study sells 20 one-off in-app purchases and TSK Bible Commentary sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

TSK Bible Commentary holds the better App Store score, 3.3 against 3.0. That said, the two scores are not equally well evidenced: Mantis Bible Study has 299 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 55% of Mantis Bible Study's written reviews are positive against 50% of TSK Bible Commentary's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mantis Bible Study ships an update every 2 days, TSK Bible Commentary every 6 months. The most recent releases landed on October 6, 2026 and October 4, 2026 respectively.
