# StemLab vs StemScriber

The clearest difference is rating: StemScriber at 5.0 against StemLab's 4.5. StemScriber also leads on review sentiment (100% vs 67%) and iOS requirement (15.0 vs 26.2). StemLab's advantage is ratings volume (28 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. StemLab sells 2 in-app purchases, starting at $4.99 per year and StemScriber sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

StemScriber holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: StemLab has 28 ratings behind it against 2, so its average is the more settled of the two.
