Verdict
The clearest difference is ads: Stack B at none against Twinby's shown. Stack B also leads on update cadence (every 6 days vs every 3 weeks) and review sentiment (95% vs 85%). Twinby's advantage is ratings volume (2.2K vs 18). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Twinby sells 16 in-app purchases, starting at $3.99 per 7 days and Stack B sells 1 in-app purchase, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.4 for Twinby against 4.4 for Stack B. That said, the two scores are not equally well evidenced: Twinby has 2.2K ratings behind it against 18, so its average is the more settled of the two. Written reviews are what separate them: 85% of Twinby's written reviews are positive against 95% of Stack B's.
Twinby ships an update every 3 weeks, Stack B every 6 days. The most recent releases landed on October 17, 2026 and October 14, 2026 respectively.
