# ChatInbox vs MemoKey

The clearest difference is review sentiment: MemoKey at 100% against ChatInbox's 62%. MemoKey also leads on rating (5.0 vs 4.5). ChatInbox's advantage is ratings volume (34 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ChatInbox sells 3 in-app purchases, starting at $4.99 per month and MemoKey sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
