Ninja Fight Clock
Read full descriptionHide full description
This is a digital and analog clock application to fight the oncoming ninjas. When a ninja attacks, touch the bottom half of the screen. You can fight back with a shuriken or a sword. You can choose the interval between attacks from 10, 15, 20, 30, and 60 minutes. Since they appear at regular intervals, you may want to use them as an alarm when you feel sleepy, such as when you are studying. Each ninja uses its own unique ninjutsu. If your attack hits them several times, you can defeat them. If you tap the scrolls that sometimes appear on the screen, you can use various ninjutsu to fight back. The ninja will leave in one minute. If you defeat them all before they are gone, you will get the scroll from the beginning in the next battle. You can choose from 20 famous Japanese castles for the castle picture. You can also turn off the ninja action and enjoy it as just a clock. ***** The time text and analog clock can be moved with your finger. The picture and analog clock can be zoomed in and out with two fingers. Touch the time text to switch to setting mode. You can change the date and time to various formats by touching it in the setting mode. You can also switch between 12-hour and 24-hour displays. The screen can be rotated horizontally and vertically. By pressing buttons such as "2X" and "3X," the font size can be adjusted in steps. 20 types of backgrounds can be selected. Time signal tone can be selected from 78 different tones.
Brutal Time

Brutal Time turns your iPhone into a brutalist desk clock. Put it on a charger and it fills the screen, edge to edge, with nothing but type. It tells time without decoration, distraction, or gimmicks. ON THE CHARGER StandBy widgets for every clock face, and widgets for the Home Screen. A full-screen, StandBy-style display for the app itself, with the status bar hidden so the clock owns the whole screen. Add a Shortcut and it opens by itself the moment you plug in. Always-On keeps it lit while charging and dims it after a few seconds, then lets the phone sleep again as soon as you unplug. FOUR TYPOGRAPHIC FACES Four distinct designs, each built on a different typographic system: digits locked to a ruled grid, editorial Swiss with a red accent, oversized poster glyphs cropped by the frame, and mono type over a dot-indexed field. Each reads as words or numerals, in dark or light, portrait or landscape. UNLOCK AMBIENT MOTION WITH THE FULL EDITION Each face can come alive. Continuous, ambient motion runs through the type โ letters that breathe, sway, and resolve on their own unhurried rhythm, with several motions for every face. Calm and deliberate, never a screensaver. Ambient Motion is the only paid feature, and the Full Edition is a one-time purchase โ buy it once, keep it forever. Everything else is free: every clock face, every typeface, every widget, the full-screen display and Always-On. Also included: - Three typefaces per face - Custom accent colors - Home Screen and StandBy widgets - No subscription. No ads. Ever. Brutal Time is shaped by brutalist design principles: visible structure, a restrained palette, and the removal of unnecessary ornament. Time is shown as type, grid, and rhythm โ clear, functional, and deliberate.

Verdict
The clearest difference is ads: Brutal Time at none against Ninja Fight Clock's shown. Brutal Time also leads on update cadence (every 10 days vs every 3 weeks). Ninja Fight Clock's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 17.0). On price and in-app purchases there is nothing between them.
