# Anchor Pro vs MRB Navigator

The clearest difference is ratings volume: Anchor Pro at 3.6K against MRB Navigator's 10. MRB Navigator's advantage is review sentiment (100% vs 79%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Anchor Pro sells 1 in-app purchase, starting at $6.99 per year and MRB Navigator sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
