Read full description

Blue Hour turns time into light: a sun sinks toward the horizon as your timer runs, so you can feel how much is left without reading a number. Built kindly for ADHD and time-blindness, calm enough for classrooms and kids. No account, no ads, no streaks. Free forever, with a tip jar in Settings. RAISE THE SUN Drag the sun up to set your time, one minute to three hours, with soft detents you can feel. Prefer numbers? Tap the readout for a keypad. Three preset chips keep your rituals one tap away. THE SETTLING DUSK As the last light falls, the sky deepens and the screen dims a few gentle stops. At zero: two slow breaths of glow, a soft haptic, and an optional two-note chime. No alarm slam. Ever. THE LIGHT FOLLOWS YOU A Live Activity keeps the sinking sun on your Lock Screen and in the Dynamic Island. An optional nudge can tell you when time is up, even if you have looked away. Off by default. CYCLES, GENTLY Pomodoro in Blue Hour's language: work while the sun sets, then the break is a sunrise. The sky returns to morning, and the next round starts when you do. Rounds are counted in little suns, never quotas. START FROM ANYWHERE A Home Screen widget starts your usual timer in one tap. Siri and Shortcuts can start, pause, and resume without opening the app. FOR CLASSROOMS One tap opens the big display: a wall-sized countdown calm enough for a whole room, with a classroom preset set from one to twenty minutes. A QUIET LINE EACH DAWN Every day the idle sky carries one line from 412 public-domain quotations. Seneca, Thoreau, Lao Tzu, old proverbs. One per day. No feed, no push, no hustle. CALM BY CONSTRUCTION β€’ Optional halfway and final-minute cues β€’ Keeps the screen awake while the light falls, if you want β€’ Wall-clock accurate: background it, come back, the light agrees β€’ VoiceOver, Reduced Motion, and Dynamic Type are first-class FREE FOREVER Every feature, free. No premium tier, no subscription. If Blue Hour earns a place on your Home Screen, there is a tip jar in Settings. It unlocks nothing. PRIVATE BY ARCHITECTURE No account. No analytics. No tracking. Blue Hour makes zero network calls, and its App Store privacy label is "Data Not Collected," the rare kind that means exactly what it says. The light keeps track for you.

About

Marko

Read full description

Marko is a fast, native Markdown viewer for iPhone and iPad. Open any .md file and read it the way it was meant to look, with real typography, syntax-highlighted code, GFM tables and task lists, Mermaid diagrams, and KaTeX math. Everything renders on your device with no network access, so your documents never leave it. Marko is a viewer, not an editor. It never changes your files. Open Markdown straight from the Files app, or share it in from Mail, Safari, or any other app, and read it full-screen with an outline, find in page, and adjustable text size. It is built for the Markdown you didn't write by hand, too: the .md that AI assistants and coding agents produce, generated READMEs, and agent output. DOCUMENT INTELLIGENCE, ON DEVICE Summarize a long document, ask questions about it, or explain a selected passage, all processed on your device with Apple Intelligence. Nothing is sent to a server. (Requires a device with Apple Intelligence.) HIGHLIGHTS - Native Swift and SwiftUI app for iPhone and iPad. Not a web app. - Renders fully offline. Your documents never leave your device. - Opens Markdown in place from Files, and via the share sheet from other apps. - Outline, find in page, and text zoom. - Light, Dark, and System themes. - Universal purchase: buy once, use on Mac, iPhone, and iPad. Marko collects no data. It has no analytics, no accounts, and makes no network requests of its own. Free. Requires iOS or iPadOS 18 or later.
