SeClock shows just the seconds on your Lock Screen or Home Screen — the part the system clock leaves out. Long-press the Lock Screen or Home Screen to add the widget. An in-app purchase lets you tune the font, weight, size, and opacity so the seconds blend into your setup. Prefer the Dynamic Island? Tap the button in the app to start a Live Activity that keeps seconds ticking there for up to about 8 hours. You can also use the app itself as a fullscreen HH:MM:SS clock. *Widgets and Live Activities may be off by up to about 1 second.

Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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