Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Bobby ships an update every 2 months, Stack monthly. The most recent releases landed on October 14, 2026 and October 2, 2026 respectively.
