# Circle vs LUMEN

The clearest difference is review sentiment: LUMEN at 100% against Circle's 43%. LUMEN also leads on rating (5.0 vs 4.3) and update cadence (every 3 days vs every 2 months). Circle's advantage is ratings volume (5.5K vs 3) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Circle sells 5 one-off in-app purchases and LUMEN sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

LUMEN holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Circle has 5.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 43% of Circle's written reviews are positive against 100% of LUMEN's.

Circle ships an update every 2 months, LUMEN every 3 days. The most recent releases landed on October 20, 2026 and October 7, 2026 respectively.
