I'm looking for a tool that will allow me to easily create mock ups in the go, when my internet connection is unreliable or nonexistent.
Must haves, in order of priority:
- Create software/website UI mockups.
- Functions without internet.
- Platform: iOS or Android.
- Support for common UI elements such as checkboxes, radio buttons, form input fields, etc.
- Export as a bitmap to share with others.
- Price: free preferred, up to £20 ok if there is a good free trial or other way to assess it first.
For bonus points:
- Cross-platform, available on both Android and iOS.
- Sync with Google Drive or Dropbox.
