SOLID is a productivity app built for professionals who want structure, focus, and consistency — without the distraction of gamer-style tools. It helps you plan your most important tasks each day, work in focused blocks, and close your day with clarity. Instead of points and avatars, SOLID uses subtle gamification: visible progress, momentum tracking, and daily feedback that makes work feel motivating while staying calm and professional. SOLID is launching soon. You can join the waiting list.
