We offer three categories of apps. We’re constantly working on new apps (and updated versions of ones we’ve used for years) and we’ll publish those as soon as they’re ready. Click the links in the sidebar to the left to see the product pages.

Productivity Apps

General-purpose programs that help you get real work done. There are 4 in this category:

Growly Calculator, a simple spreadsheet app that also has three specialty calculator windows. Easy formula construction and incredible control of display, without unnecessary complications.

Growly Draw, a drawing app for people who aren’t artists. Work with shapes that can be adjusted at any time, and bitmaps like photos, all in the same document.

Growly Notes, a note-taking app somewhat like Microsoft OneNote®. Gather text, images, links and anything else you can think of in free-form pages organized into sections. This is our only paid app, available on the Mac App Store.

Growly Write, a small but capable word processor. Create great-looking documents with ease. No feature overload here, just the things you’ll use every day.

Home Apps

These are programs for accomplishing specific tasks at home. They’re capable but very simple, targeted to the task at hand. There are 6 in this category:

Growly Backup, for performing on-demand backups of your critical files.

Growly Calendar, for sharing a calendar on multiple computers in your home or office without needing an iCloud account or a server.

Growly Checkbook, a no-frills electronic checkbook register that manages checking and savings accounts.

Growly Groceries, a shopping list manager.

Growly Journal, a multi-year personal diary that makes it fun to keep a record of the events, accomplishments, and activities in your life.

Growly Photo, a simple organizing tool for your photo files.


No shoot-em-ups or 3D, just good old-fashioned time wasters. There are 5 in this category:

Growly Backgammon, perhaps the oldest board game.

Growly FreeCell, one of the easiest solitaire games to win.

Growly Rummy, a structured, progressive rummy game.

Growly Solitaire, the classic one-person card game.

Growly Spite & Malice, a solitaire-like card game played against the wicked computer.

Download instructions

You can find Notes on the App Store (on the Apple menu) or click the “Buy Now” button on the Notes page.

  • Click the Download button on any of our product pages (follow the links in the sidebar on the left). The program disk image will be copied to your Downloads folder.
  • The download may be automatically opened, depending on your version of Mac OS. Recent versions do not do this.
  • If it was not automatically opened, find your Downloads folder (Go/Home in the Finder) and look inside. The name will be something like write_127.dmg, starting with the name of the app you downloaded.
  • Double-click the dmg file, drag the program into your Applications folder, start it up, and have fun.

Mountain Lion (10.8) and later security settings

All of our apps work on Mac OS 10.8 Mountain Lion and later but you may have to change your security settings to allow them to run. If you have a problem, go to System Preferences, click on Security & Privacy, and select the option “Allow applications downloaded from anywhere.”

If you’re uncomfortable with this, you can allow apps to run on a case-by-case basis by control-clicking an app, choosing Open from the context menu, and then confirming that you want to start the app.
