What's New in FractRoam

2.0.1

July 21, 2026

2.0 is rebuilt from the ground up—the new autopilot swims continuously through the fractal — diving into detail, then surfacing to explore somewhere new. Tap once to take the wheel; tap again to let it roam. • Rebuilt on Metal — silky-smooth, with deeper, sharper zooms • Six moods — recolor the whole set, and preview your view in all six palettes at once • Immersive, full-screen landscape • A gentle learn-by-watching intro, a redesigned About, and cleaner sharing Turn it on, set it down, and watch where it wanders.

App Creator

i always enjoy Apps of this nature. Sometimes just playing around in this App, ‘something’ in an image, triggers an experience 🤔. Good thing.😀
i don’t know (or care) what the previous post (the cat karen🥸),’problems’ are. But delete👎🏾 (imho) that post. Negativity😾 drips from what turns out to be a good👍🏻👍👍🏽 App.

Nice, but ....

Limit zoom, no display of coordinates or
Zoom factor, little control of color pallet, landscape mode only, controls are difficult to see.

Low resolution

I can't really view anything important, since it gets to be really low resolution at high zoom. Recalculate the fractal, come on!

Portrait mode is NOT standard

Donlively said this “forces ... into landscape”, stating it couldn’t be used in “standard” mode, ie portrait. I don’t see a problem reorienting to portrait mode to use this- its default landscape orients my phone upside down, to my preference so I reorient anyway. Viewing either mode as standard ignores the reality that using either mode consistently can result in real injury. I have bone spurs on my left thumb (real ones) and undx injury to my right wrist that get worse when forced to use only portrait mode. Devs should be aware of this; we’ve been through epidemics of injury caused by poor tech design and people suffer (not as badly as Tyson chicken processors). I use external keyboards for my phone- yes, iPad keyboards work even if the phone is too small for the case- and it helps but we need more conscious design.

Fractals: In elementary school I wasn’t taught to see a subject and draw; instead I was told “this is how you draw a cat, a chair, a tree... ”. Dumb thing to do; I finally learned to see/draw as an adult. I was “taught” to draw trees as fractals- all well and good if you want to draw a tree as a fractal but not any real tree. Fractals may come into play on a cellular level of a tree but not so much on the gross visual level.

Limited zoom

One should be able to continue to resume with full details. With this app once you zoomed all the way in the gets very pixelated and you can zoom no further.
