# PortalGate vs Chroma

The clearest difference is rating: Chroma at 5.0 against PortalGate's 3.7. Chroma also leads on update cadence (daily vs every 15 months) and review sentiment (62% vs 44%). PortalGate's advantage is monetization model (free vs free with in-app purchases) and ratings volume (6 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PortalGate sells 1 one-off in-app purchase and Chroma sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

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