This is the support page for MathTech, MathTech min and MathTech Free. Most application problems can be solved by either restarting the device or reloading the application from the app store. If neither of these resolves your problem, and it is not addressed in this FAQ, then please email support
How do I import documents into my app?
Most email clients, including Apple's Mail app, K-9 Mail, Hotmail, and Yahoo! Mail allow you to touch an attached MathTech file, launch MathTech, and import the document. Files may also be transferred between the iPad and Android versions of MathTech and a consistent 1024 x 1024px canvas drawing area is maintained in versions 3.0 and later.
Can I import equations I've created in MathTech into the TechDraw app?
Yes. For both the iOS and Android versions, TechDraw is a superset of the functionality in MathTech and can import files created in that app.
When I touch a text block, it doesn't show as selected.
This is caused by the current layer being different than the layer assigned to the shape. If there are no shapes selected you can determine which shapes are assigned to which layers by selecting each layer in turn - the shapes asigned to each layer chosen will then have their bounding box displayed.
Why doesn't the app operate in landscape orientation?
In order to provide a consistent canvas size and to optimize the keyboard design, MathTech is constrained to work in portrait orientation only on phones. Both portrait and landscape orientations are supported on tablets.
Do I need to be online to use TechDraw?
The full version of TechDraw can be used offline except for the export of data or images. TechDraw Free and TechDraw min require online access for all functions.
Can I export my equations into other applications?
With the document you want export showing on the canvas, select "Share..." from the menu, then choose how you'd like to export an image of your document. You can store it in the pictures directory of your device, email it, or use any of the other sharing mechanisms. You can then use the exported image as part of a presentation or other document.
