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 — 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 — 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 — clear, functional, and deliberate.

Verdict
The clearest difference is in-app purchases: TetraClock at none against Brutal Time's 1. TetraClock also leads on update cadence (every 2 days vs every 3 weeks) and device support (3 vs 1). Brutal Time's advantage is ads (none vs shown). On price there is nothing between them.
