# Spark vs Mentor

The clearest difference is rating: Mentor at 5.0 against Spark's 4.5. Mentor also leads on review sentiment (100% vs 76%). Spark's advantage is update cadence (weekly vs every 2 months) and ratings volume (51 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Mentor holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Spark has 51 ratings behind it against 1, so its average is the more settled of the two.
