About this app

FracTime turns focused work into something you can actually see grow.

Start a focus session, and instead of a generic timer or a cartoon tree, you watch a real mathematical fractal build itself, one recursive layer at a time, for exactly as long as you stay on task. When the session ends, that fractal becomes a permanent specimen in your personal Collection: a real, provable record of the time you spent focused.

HOW IT WORKS
• Set a task and a duration, then start focusing.
• Your fractal grows in real time as the session progresses. The longer you focus, across sessions, over weeks and months, the more intricate it becomes.
• Finish the session and the fractal is saved forever as a specimen, complete with the exact seed, palette, and shape that grew from it.
• Every specimen is unique, deterministic, and yours to keep, tag, favorite, and revisit.

MAKE IT YOURS
Choose your own palette and background from a wide, growing set of options (soft pastels, deep space, warm embers, cool glaciers), or shuffle until something clicks. Star your favorite fractal families for a curated "Surprise me" pick, and FracTime can suggest a sensible starting duration from how you like to focus, right from your first session.

PROJECTS
Group your sessions under a named Project: a thesis, a language, a semester. Watch its gallery, cumulative focus time, and session history build up across everything you grow under it, even when every session grows a completely different fractal.

REAL MATHEMATICS, NOT DECORATION
Every shape in FracTime is a real, mathematically accurate fractal, the same constructions studied in geometry and chaos theory, rendered live as you focus.

Nineteen families free forever, including Koch Snowflake, Sierpiński Triangle, Pythagoras Tree, Dragon Curve, Barnsley Fern, and Cantor Set.

Premium packs unlock rarer, more intricate families: space-filling curves (Hilbert, Peano, Gosper), the Apollonian Gasket's infinite circle-packing, golden-ratio flakes, and chaos-theory attractors like the Lorenz Butterfly, built from thousands of accumulating points.

NO ACCOUNT. NO ADS. NO TRACKING.
FracTime works completely offline. There's no sign-up, no analytics, no ad network, and nothing about your focus sessions ever leaves your device unless you choose to export or share it yourself. Everything (every specimen, every session, every setting) lives locally in your Collection for as long as you want it.

FEATURES
• Four app themes: Dark and Light free, Pastel and Metallic as one-time unlocks
• Gentle and Strict focus modes, so a quick phone check doesn't have to ruin a session
• Step away mid-session and FracTime keeps your last unfinished session ready to resume, so you can finish it before starting another
• A full Collection: search, sort, filter, favorite, and tag every specimen you've grown
• A Field Guide explaining the real math behind every fractal family
• Badges: a full achievement list, locked and unlocked, so you always know what's still out there to earn
• Optional streaks, weekly summaries, and a private weekly focus goal, all off by default, entirely your choice to turn on
• A Statistics screen tracking your focus time over time
• Local notifications when a session finishes, even if the app is in the background
• Export and restore your data any time: a full backup you control, merged in on restore, never overwritten
• Share a specimen as an image: pick one, four, or nine from your Collection and drag them into exactly the order you want
• An interactive Android home-screen widget: start a session or watch a live focus counter without opening the app
• Optional ambient focus sounds: colored noise or real nature recordings
• High-contrast, colorblind-friendly, and reduced-motion options for accessibility

FracTime doesn't gamify focus with points or leaderboards. It just gives you something real to look at when you're done: a shape that only exists because you did the work.
