Fractal Dive
Zoom into fractals forever
Free · In‑App Purchases
Most fractal apps stall around a thousand trillion times magnification. This one keeps going — past a 1 with three hundred zeros after it.
A fractal is one simple rule, repeated without end. The result is a shape that never runs out: the closer you look, the more there is. Fractal Dive lets you see that for yourself — and keeps computing where other apps give up.
PINCH, AND KEEP PINCHING
Nearly every fractal app stalls around a thousand trillion times magnification. That is no coincidence: it is exactly where the precision of ordinary computer numbers runs out, and the picture breaks into blocks.
Fractal Dive works differently. One orbit is computed on the processor using numbers of arbitrary length; the graphics chip then computes only the differences from it. Tested to four times ten to the power 331 — a magnification with 331 zeros — and there is still no bottom in sight.
PRESS DIVE
No idea where to look? Press Dive. The app finds the richest part of the shape by itself and travels there, for minutes if you like, deeper all the while. No two dives end up in the same place.
MADE TO LOOK AT
Nine colour schemes, from quiet silver to full rainbow — three free, all nine in Pro. The colouring reweighs itself at every depth, so a deep zoom never turns into one flat wash. Save or share any picture.
THREE FAMILIES
The classic Mandelbrot set, the same rule with a third power, and a mirrored variant with sharp points instead of bulbs. All three go equally deep.
NO MATHS REQUIRED
Twelve named places with a one-line explanation each, so you start somewhere beautiful straight away. Along the way the app tells you how small you are looking: like a magnifying glass, like a microscope, smaller than a cell, smaller than an atom — and further still.
ON ALL YOUR DEVICES
The same app on iPhone, iPad and Mac. On the Mac with keyboard, scroll wheel and trackpad.
PRO, IF YOU WANT IT
The app is free, and endless zooming stays free. A single one-time purchase unlocks Pro: pictures in 4K and 8K, sharp enough for a wallpaper or a print, and every colour scheme. No subscription. Buy once for iPhone, iPad and Mac together, Family Sharing included.
HONEST
No account, no ads, no subscription. Fractal Dive collects nothing about you; its only contact with the internet is the App Store, for the Pro purchase.
