Currently, SimpleDiagrams Free Version has almost all of the features of the Full Version, but you'll be reminded every so often that you should upgrade to the Full Version.
(Full Version users get to export to BaseCamp, and, as SimpleDiagrams grows over time, new features will be added to the Full Version making it increasingly worth your while to upgrade.)
Upgrading to the Full Version is a simple process: you come back to this site, go the buy page, and click buy. This will take you to PayPal to complete the purchase. When the purchase is complete, you will receive a license key via the email linked to your PayPal account. You can then enter this key into the SimpleDiagrams application when you first start it up to complete the upgrade process.
Here are a few things you can use SimpleDiagrams for:
- Creating process flows
- Describing a business idea
- Capturing a hand-drawn diagram and preserving it's coffee-house feel
- Plans for crashing the neighbor's barbecue
