Verdict

The call

The clearest difference is price: Circuroid at Free against Fast Reflex's $0.99. Circuroid also leads on rating (4.8 vs 4.5). Fast Reflex's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 6 weeks). On ratings volume, in-app purchases, device support and iOS requirement there is nothing between them.

Circuroid is free to download; Fast Reflex costs $0.99 up front. Circuroid sells 6 one-off in-app purchases and Fast Reflex 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

Circuroid holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 122 and 47 respectively. Written reviews complicate that: 88% of Circuroid's written reviews are positive against 100% of Fast Reflex's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Circuroid ships an update every 6 weeks, Fast Reflex every 2 weeks. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
