# Circle vs SÜMOB

The clearest difference is review sentiment: SÜMOB at 100% against Circle's 50%. SÜMOB also leads on price (Free vs $1.99) and update cadence (every 10 days vs every 29 months). Circle's advantage is rating (4.5 vs 3.0). On ratings volume, ads, in-app purchases and device support there is nothing between them.

SÜMOB is free to download; Circle costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Circle holds the better App Store score, 4.5 against 3.0. Both are backed by a comparable volume of ratings — 2 and 2 respectively. Written reviews complicate that: 50% of Circle's written reviews are positive against 100% of SÜMOB's, so the app with the better star average is not the one people write more warmly about.

Circle ships an update every 29 months, SÜMOB every 10 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
