Verdict
The clearest difference is review sentiment: Stack at 100% against Bobby's 56%. Bobby's advantage is rating (4.7 vs 3.7) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bobby sells 6 one-off in-app purchases and Stack sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Bobby holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Bobby has 8K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of Bobby'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.
Bobby ships an update every 2 months, Stack monthly. The most recent releases landed on October 14, 2026 and October 2, 2026 respectively.
