Looking for a clock that is easy to read? Mugen Clock fills the screen with large numbers and beautiful, vivid colors to make the time easy to see. It brings together the features you expect from a clock app, including a kitchen timer and stopwatch, in a simple design. And it offers more than readability. You can customize it in many ways to make it your own. For example, you can show or hide the weather, temperature, date, day of the week, and seconds, and control the screen orientation. You can also set a favorite photo as the background or display a live camera view with stylish effects. Carefully selected color themes can completely change the look and feel. The combinations are endless. You can save the clocks you create, too. Switching between saved clocks to suit your needs or your mood is easy. It does more than show the time: a simple, easy-to-use timer is also built in. Keep it nearby while studying, cooking, or exercising. The ways to use it are endless, too. Make this clock part of your everyday life.

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 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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
