Chromeo is a visual Pomodoro timer built for creative work. Instead of only watching numbers count down, you see time unfold visually. A spiral closes. A ring fills. A maze resolves. A cube shifts. You observe time passing. Time is set through touch. Haptic feedback makes adjustments feel physical and precise. You can edit the timer even while it is running. Sessions are meant to adapt to your workflow, not lock you into it. Chromeo is fast to use. Open, set, start. No setup screens, no friction. It works well for: • Deep creative work • Writing, design, development • Study sessions • Time blocking • ADHD and neurodivergent users • Anyone who prefers to feel time instead of reading it Different tasks can have different visual styles. Focus can look different depending on what you are doing. Designed for the Senses • Beautiful 3D parallax visuals • Minimal, clean UI • Fast and reliable performance • Haptic precision control By using this app, you agree to Apple's standard Terms of Use.

Verdict
The clearest difference is in-app purchases: Better Calculator at none against Chromeo's 2. Better Calculator also leads on device support (4 vs 2) and iOS requirement (15.0 vs 17.0). Chromeo's advantage is update cadence (every 2 days vs weekly). On price and ads there is nothing between them.
