# Aida vs Index

Aida and Index are too close to call on the numbers: across 6 compared parameters — price, ads, in-app purchases and monetization model among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

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