# Mugen Clock vs SeClock

The clearest difference is review sentiment: Mugen Clock at 95% against SeClock's 58%. Mugen Clock also leads on ratings volume (63 vs 4). SeClock's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Mugen Clock sells 1 one-off in-app purchase and SeClock sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SeClock holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Mugen Clock has 63 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 95% of Mugen Clock's written reviews are positive against 58% of SeClock's, so the app with the better star average is not the one people write more warmly about.

Mugen Clock ships an update every 9 days, SeClock fortnightly. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
