What is Mossy?

Editorial review
Mossy is a minimalist macOS app that lives in the corner of your screen as a small plant. When you spend too long at the keyboard without stepping away, the plant wilts and asks you to take a break. You can click it at any time, and it will present a single short exercise, written by AI based on a sentence you write, with a timer. The exercise is never the same twice and is sized to fit the break. After completing the break, the plant returns to health and a tiny sprig grows at its feet, recording one break per day. Your history, settings, and garden remain on your Mac. No account is required, and the only data sent to the AI server is your typed sentence plus the last three notes you wrote, nothing is stored on the server. Mossy is entirely free and works on macOS 12 or later.

Is Mossy worth the price?

95/100

The pricing is extremely generous since the only tier is Free with no paid upgrade path, making it a rare zero-cost tool for desk workers.

This is a fantastic deal for anyone who needs a gentle nudge to take breaks, but the lack of a paid tier means no advanced features like team sync or analytics. Best for individual Mac users who want a simple, AI-powered break reminder without spending a dime.

Mossy FAQ

How does the plant decide when to ask for a break?

Mossy counts your keyboard and trackpad activity. If you haven't stepped away for a while, the plant begins to wilt as a gentle reminder. It never blocks your work — it simply asks, and you click when it suits you.

Can I choose my own exercises instead of using the AI?

No, the app is designed around AI-written exercises. You supply a sentence in your own words, and the AI reads that plus your last three notes to generate a unique, timed exercise — there is no fixed list of stretches.

What happens if I step away from the computer mid-break?

The break timer freezes when you are away from the keyboard and trackpad. Mossy automatically pauses and resumes, so you can take the break at your own pace without losing progress.

Does Mossy store any of my data on its servers?

No. Only the sentence you type and your last three notes are sent to the AI server to write the exercise, and that data is not kept. All your history, garden, and settings remain on your Mac.

How can I see which days I have taken breaks?

Each completed break grows a sprig at the plant's feet. The garden shows one sprig per break for the entire week, arranged from Monday to Friday, giving you a quick visual history at a glance.

Is Mossy a full pomodoro timer or just a break reminder?

Mossy is not a work timer — it only reminds you to take a break and provides a single short exercise. It does not track work sessions or intervals; its role is purely to encourage brief, mindful pauses.

Can I customize the duration of the break?

The break length is fixed — it is a brief, timed exercise. You do not set a custom duration. The AI writes the exercise to fit the standard short break size.

What happens if I ignore the wilting plant?

The plant continues to wilt, but Mossy never forces you to stop working. It simply sits in the corner and waits. You can click it at any moment that suits you to start the break.
