# Training Karyotypes vs BM Counter

The clearest difference is ads: Training Karyotypes at none against BM Counter's shown. Training Karyotypes also leads on rating (4.5 vs 4.2) and monetization model (free vs ad-supported). BM Counter's advantage is review sentiment (86% vs 67%) and ratings volume (10 vs 2). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Training Karyotypes holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: BM Counter has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Training Karyotypes's written reviews are positive against 86% of BM Counter's, so the app with the better star average is not the one people write more warmly about.

Training Karyotypes ships an update every 38 months, BM Counter every 72 months. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
