This app is free from the Apple App Store for iPad. This App is not available on iPhone at this time. It is not restricted to Janome WIFI embroidery machine models. You can email what you create out of the AcuSketch App to your computer, save on a USB stick and open at the embroidery machine.
This image shows an example of what you can do with AcuStitch. A picture was used and outlined in AcuSketch and then embroidered on a sweater. Bows were added for more dimension.
