Please notice - You should compare an apple to an apple.
1. iPlanner Pro is just one of the services you get in the iPlanner Business Collection. iPlanner for Outlook, Excel (with GANTT chart) and SharePoint Online and Group Sites.
2. iPlanner is a true Office add-in. NOT A COM Add-in, no local installation, this means
- nothing to make your Outlook client crash.
- No updates to install
- avilable on ALL devices
3. iPlanner do NOT save any data localy or on the providers (our) server or service. All is on YOUR office 365. This means we follow the new EU data requirements.
There are other product that can do much more and have more functionality. The question is what is importnat for you.
For íPlanner Pro it is extremely important, that all the add-ins in iPlanner Business Collection follow the authentication and consent model required by Microsoft for Office 365 Add-ins. Nor do we want to store data localy or have your data on our server. All is on your O365!.
Yes this give some limitation to what we can offer at the moment. But as soon as Microsoft add functions to the API, so will we update the features of the Add-in.
Still I belive iPlanner Pro offer very rich functionality - on all devices - I hope this clarify what is important for the iPlanner Pro and the product. To test it you get the full functionality the second you add-it to your Outlook from the Store.
