# EMEPA vs Kyanite Pro

The clearest difference is rating: Kyanite Pro at 5.0 against EMEPA's 3.7. Kyanite Pro also leads on update cadence (every 5 days vs every 6 months). EMEPA's advantage is in-app purchases (none vs 2) and ratings volume (6 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Kyanite Pro sells 2 in-app purchases, starting at $3.99 per month. EMEPA asks for nothing beyond the download.

Kyanite Pro holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: EMEPA has 6 ratings behind it against 1, so its average is the more settled of the two.

EMEPA ships an update every 6 months, Kyanite Pro every 5 days. The most recent releases landed on October 14, 2026 and October 16, 2026 respectively.
