Ideas don't move on inspiration alone.
Aravel breaks an idea into steps and links what depends on what, so the next move rises to the surface.
■ See every idea at a glance
Tie ideas together with "this has to finish before that starts," and the dependencies in your head become a radial map. Pinch to zoom out, tap to open any idea.
■ Know what to do next
The list shows prerequisites and status side by side. What's waiting and what's ready to move reads at a glance.
■ Get back to what you're working on
As projects pile up, star the ones that matter and they gather at the top of the list. Whatever you're moving on right now is there the moment you open the app.
■ Build your own workflow
Name your own statuses and pick their colors. You choose which ones count as done, so completion means what it means to you.
■ Every change stays on record
Status changes and memo edits stack onto a timeline. Trace back why you decided what you did.
■ Think it through with an AI that knows the project (paid plan)
The AI reads your ideas, their dependencies, status, and history — so instead of one-off answers, you work through what to do next together. Starts with a 14-day free trial.
■ Your data stays on your device
Projects, ideas, and history are all stored on your iPhone. No account, no sync server, no ads.
Note: only when you use the AI chat on a paid plan are your messages and idea content sent to Google's Gemini to generate a reply. The app tells you when it does.
