Description

I developed LogoPlus with one clear goal in mind: I want to educate and inspire the next generation of software engineers in the same way I was educated and inspired in my youth. Writing Logo programs give young minds the opportunity to explore procedural programming, graphics, algebra and geometry; and have so much fun they don't realize that they're actually learning something useful.

• Easy to use — Simple and intuitive interface
Tap, swipe, pinch and shake - this app works exactly the way you would expect a proper iOS app to work. You can even rotate your iOS device to the orientation that works best for you.

• Powerful — Supports user-defined functions and recursion
User-defined functions allow you to simplify your code by refactoring common operations (such as drawing a geometric shape) into reusable chunks. Full support for true recursion means that you can draw complex objects including fractals with ease.

• Universal app — Supports both iPhone and iPad
You won't get left out no matter which iOS device you use. All screen orientations and resolutions are supported on all iOS devices.

• iCloud integration — Share your documents across all your devices
If you have chosen to enable iCloud on your iOS device then your LogoPlus documents are automatically stored in iCloud and therefore are instantly shared across all of your devices. In the event that you make conflicting changes to a document on more than one device, an unobtrusive notification will show up allowing you to resolve the conflict at your convenience.

• Real program editor — No obfuscated interfaces here - copy and paste code samples from any source
Edit your LogoPlus programs using the built-in text editor. Copy, paste and shake to undo are all supported.

• High-resolution drawing — OpenGL vector graphics support infinite resolution
You can zoom in to see the smallest geometric detail or zoom out to see the big picture. Zooming, panning and double-tap are fully supported, even while your program is still running.

• Built-in help — Detailed help available at your fingertips
LogoPlus includes comprehensive and detailed help built-in so you can always get the help you need, whether you have a network connection or not.

• Samples included — Includes useful sample programs to get you started
Hit the ground running with great sample programs that demonstrate features such as turtle drawing, repeat loops, random numbers, user-defined functions and recursion.

Customer Reviews

LogoPlus

Many years ago, I taught elementary teachers how to program in Logo, using MIT Terrapin Logo. This Ipad app is very close to that original MIT language. This the best Logo available for the IPad. It was a bit of a puzzle about how to use a defined procedure within another procedure,but as long as they are in the same document it will work. This app fully supports the use of variables, repeat structures and recursion. Well done!

Problem with SETPENSIZE

You see, I have a concern about this app: SETPENSIZE doesn't appear to work if you want it to be a set variable. This is based on what I tried to do on my iPad 2. This may need to be fixed when the next update comes. You may want to attempt what I did, and it doesn't work. I'd recommend to avoid it.

Thanks

Thanks!...
