Tiimo is a visual, pictogram-based AI planner built specifically for ADHD and autism executive-function support, and was named Apple's 2025 iPhone App of the Year. Chrobox is a general-purpose timeboxing app for phones that adds automatic app blocking during each time box, but does not have Tiimo's ADHD-specific design or free tier.
Choose Tiimo if you specifically need ADHD/autism-oriented visual planning, want a free tier to start, or use a Mac or Apple Watch. Choose Chrobox if you want a straightforward timeboxing app that also blocks distracting apps during your scheduled work, and you are comfortable planning from your phone only.

Common questions about Chrobox vs Tiimo
Chrobox is a reasonable alternative if you want general timeboxing with automatic app blocking, since Tiimo does not block apps. It is not a substitute for Tiimo's ADHD/autism-specific visual design, free tier, or Mac and Apple Watch apps, which Chrobox does not have.
Tiimo is a pictogram-based visual planner purpose-built for neurodivergent executive-function support, with a limited free tier and apps across Mac, Apple Watch, Vision Pro, and the web. Chrobox is a phone-only, subscription-only timeboxing app whose main structural difference is automatic app blocking tied to each planned time box.
No, app blocking is not part of Tiimo's documented features. Tiimo focuses on visual, AI-assisted planning and calendar import; if you want your planned time to also lock distracting apps, that is a Chrobox-specific feature.
