Verdict

The call

The clearest difference is in-app purchases: ConTutor at none against BitDynamic's 10. ConTutor also leads on review sentiment (50% vs 29%). BitDynamic's advantage is rating (4.3 vs 3.8) and ratings volume (6.5K vs 11). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

BitDynamic holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: BitDynamic has 6.5K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 29% of BitDynamic's written reviews are positive against 50% of ConTutor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BitDynamic ships an update every 10 days, ConTutor every 2 weeks. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
