Verdict
The clearest difference is rating: IMBox Defense at 4.7 against Unify Circuit's 2.7. IMBox Defense also leads on in-app purchases (none vs 1) and update cadence (fortnightly vs every 6 weeks).

Both are free to download. Unify Circuit sells 1 one-off in-app purchase. IMBox Defense asks for nothing beyond the download.
IMBox Defense holds the better App Store score, 4.7 against 2.7. That said, the two scores are not equally well evidenced: Unify Circuit has 71 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 51% of Unify Circuit's written reviews are positive against 23% of IMBox Defense's, so the app with the better star average is not the one people write more warmly about.
Unify Circuit ships an update every 6 weeks, IMBox Defense fortnightly. The most recent releases landed on October 22, 2026 and October 21, 2026 respectively.
