Verdict
The clearest difference is review sentiment: Tower Stack at 100% against Circle's 43%. Tower Stack also leads on in-app purchases (none vs 5) and update cadence (every 6 days vs every 2 months). Circle's advantage is ratings volume (5.5K vs 1) and rating (4.3 vs 4.0). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Circle sells 5 one-off in-app purchases. Tower Stack asks for nothing beyond the download.
Circle holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Circle has 5.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of Circle's written reviews are positive against 100% of Tower Stack's, so the app with the better star average is not the one people write more warmly about.
Circle ships an update every 2 months, Tower Stack every 6 days. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
