Read full description

A prayer rope is a loop made up of complex woven knots formed in a cross pattern, usually out of wool or silk. This app gives you the opportunity to pray as having a prayer rope on your hand by having an Apple Watch on it. The watch ticks every time to say the prayer keeping your mind focused. Integration with HealthKit keeps track of how much you pray. You can configure the number of ticks and the interval. The tick on the watch is gentle so you can pray without distracting the attention of others. Lord Jesus Christ, Son of God, have mercy on me, a sinner

Verdict

The call

The clearest difference is rating: OrthoPrax at 4.7 against Koboskini's 4.2. OrthoPrax also leads on update cadence (every 2 months vs every 11 months) and ratings volume (520 vs 5). Koboskini's advantage is in-app purchases (none vs 1) and review sentiment (75% vs 51%). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OrthoPrax holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: OrthoPrax has 520 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 51% of OrthoPrax's written reviews are positive against 75% of Koboskini's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OrthoPrax ships an update every 2 months, Koboskini every 11 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
