FractRoam is a real-time explorer for the Mandelbrot and Julia sets — and its heart is the autopilot. Press play and let it roam: FractRoam continuously seeks out the most visually interesting regions of the fractal and glides you through them, an endless, ever-changing tour you can simply sit back and watch. Want to take the wheel? Pinch and drag to wander on your own, and recolor the whole scene with a tap. Everything is drawn pixel-by-pixel on your device's GPU, in real time. FEATURES • Roam autopilot — hit play and drift through a continuous, auto-discovered tour of the fractal • Real-time Mandelbrot and Julia set rendering, GPU-accelerated and smooth • Pinch and pan to explore yourself, or hand it back to the autopilot anytime • Color moods — six hand-tuned palettes plus animated color cycling • Share any view — a picture plus a link that reopens the exact same spot • Fully offline — no account, no ads, no data collection • A calm, full-screen interface — just you and the fractal Whether you want something mesmerizing to get lost in, a generative-art source for textures and wallpapers, or a hands-on way to explore the math of self-similarity, FractRoam turns the Mandelbrot and Julia sets into something alive.

Verdict
The clearest difference is price: Spiralflow at Free against FractRoam's $0.99. Spiralflow also leads on review sentiment (100% vs 86%) and iOS requirement (9.2 vs 12.0). FractRoam's advantage is rating (4.3 vs 3.3) and ratings volume (75 vs 4). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Spiralflow is free to download; FractRoam costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
FractRoam holds the better App Store score, 4.3 against 3.3. That said, the two scores are not equally well evidenced: FractRoam has 75 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 86% of FractRoam's written reviews are positive against 100% of Spiralflow's, so the app with the better star average is not the one people write more warmly about.
