Purchase Online

To purchase any Developer One software title online, simply click on the Buy Online button that you'll find on every product page.  This will add the product to your online shopping cart.  From your shopping cart you may continue shopping or proceed to complete your purchase by entering your billing and payment information.  

We have partnered with Handango to provide our secure online transactions for purchasing software online from our web site.  All of your purchase information is securely transmitted in the processing of your order.

Once you have completed your purchase online, you will have the opportunity to download a full/retail version of the product.  Where full/retail versions of the product are made available for download, you simply download the full version of the product and install it directly over your trial (if you already have a trial version of our software installed.)  The email receipt you will receive from Handango will also include a link to allow you to re-download your purchased items at any time should you need another copy of the full/retail installation programs.

Note for products using registration codes
Several of our products now utilize registration codes.

  • Agenda One

  • Agenda Fusion 5 and later for Pocket PC

  • iFitOne

  • CodeWallet Pro 5 and later for Pocket PC, Smartphone and Desktop PC

  • Power Tasks for Smartphone

  • Power Calendar for Smartphone

When purchasing any of these products, you will also receive an email from Developer One immediately after completing your order (no long delays like many other software developers.)  The user ID and Registration Code you receive may be used to unlock the trial version of the software and remove the time limitations.

Should you ever misplace your registration code, you may retrieve another copy at any time.

    Please make sure to check current exchange rates.  Make sure you wrap any paper money in two to three sheets of paper for security.  How safe is this?  In 8 years, we've not had one mail that has been lost.  So, the risk of sending cash is low, but it's there.
