# NerdWallet vs Stack

The clearest difference is review sentiment: Stack at 100% against NerdWallet's 34%. Stack also leads on ads (none vs shown). NerdWallet's advantage is rating (4.8 vs 4.3) and in-app purchases (none vs 1). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Stack sells 1 one-off in-app purchase. NerdWallet asks for nothing beyond the download.

NerdWallet holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: NerdWallet has 125K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 34% of NerdWallet's written reviews are positive against 100% of Stack's, so the app with the better star average is not the one people write more warmly about.

NerdWallet ships an update fortnightly, Stack every 6 weeks. The most recent releases landed on September 24, 2026 and September 11, 2026 respectively.
