Ship the code. Log the time. Send the invoice.
Developers often work across multiple codebases. Keeping the billing clean is an unpaid job. Aeto handles the separation automatically; in the browser while you're in your editor, or from the Mac menu bar if you're on Apple Silicon.

You're billing three clients on different hourly rates, and your current time tracker has no idea which ticket belongs to which invoice.
Freelance developers often work across multiple client codebases at once: a retainer here, a project there, a quick fix for an old client on the side. Keeping the billing clean is its own unpaid job. Aeto handles the separation automatically. Every time entry belongs to a task, every task belongs to a project, and every project belongs to a client.

Answers to the questions we get most.
Everything you're likely to ask before you download the trial.
Q.01Is Aeto good for freelance developers?
Yes. Aeto is built for freelancers who manage multiple client projects, track billable hours by task, and invoice. It runs as a native Mac app with a menu bar timer that works in the background while you're in your editor or terminal.
Q.02Can I keep billing separate for multiple clients?
Yes. Every project in Aeto is scoped to a client. Time tracked on one client's project never appears on another client's invoice. You can work across multiple clients in a day and the billing stays clean automatically.
Q.03Does Aeto support flat-fee development projects?
Yes. Flat-fee projects in Aeto let you invoice at an agreed amount while still tracking internal hours. You see your effective hourly rate on every fixed-price job, which is useful for quoting future projects more accurately.
Q.04Does the timer work while I'm coding?
Yes. The Aeto menu bar timer starts in the web app or from your Mac menu bar without switching apps. It runs in the background while you're in your editor, browser, or terminal and logs to the correct project when you stop it.
Q.05Is there an iOS or Windows version?
Not yet. Aeto is web- and macOS-first. An iOS companion app is on the roadmap. Windows isn't planned at this point.
Q.06Can I charge different amounts for different clients or projects?
Yes. You can even charge different amounts at the task level.
