Thoughts Left is a brain dump app for people who think too much: late-night spirals, half-finished ideas, things you keep checking, things you're scared to forget. Get them all out fast, before the mental clutter takes over. Capture however it comes to you. Type it, speak it as a Spoken Thought, or snap it. No structure required, no "right way" to do it. Then decide on your own time. Turn thoughts into a task or a note, or simply let them go with one swipe, because not every thought needs to become something.
