Verdict

The call

The clearest difference is rating: Quartr at 4.7 against Biostock's 4.0. Quartr also leads on ratings volume (495 vs 1). Biostock's advantage is monetization model (free vs free with in-app purchases) and review sentiment (100% vs 89%). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Quartr holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Quartr has 495 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of Quartr's written reviews are positive against 100% of Biostock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Quartr ships an update every 5 days, Biostock every 6 days. The most recent releases landed on October 29, 2026 and October 31, 2026 respectively.
