Solid Apps

Solid Apps is a family of small, focused productivity apps for iOS, iPadOS, and macOS, built around personal organization rather than team collaboration. Individual apps cover different needs: Solid Calendar adds natural-language scheduling, Solid Notes offers quick capture and categorization, Solid Diary provides a private, AI-assisted space for personal journaling, Solid Habits and Formed support habit building with social accountability, Solid Planner combines a timer with an agenda view, and Fit.AI addresses fitness tracking. Evo bundles core functionality from across the suite into a single all-in-one app for users who don't want to manage several separate apps. Each app can be purchased individually, or unlocked together through a shared subscription, with exact pricing varying by region and set through the App Store. The company states that user data is encrypted and that it does not work with advertisers or trackers, positioning the suite around privacy rather than ad-supported free tiers. Solid Apps is made by Solid Apps S.R.L. and is built specifically for Apple's ecosystem; there is no Android version and none is currently planned. The tradeoff of this focused, single-purpose-app approach is that users who want one unified tool may need to rely on Evo or manage multiple separate subscriptions instead.
