Implementing iPad and iPhone drawing synchronization via iCloud is a top priority for us. Your work is invaluable, and we want to take careful steps to ensure it remains protected. The project has been in the works for over six months and is on its way.
We intend to deliver iCloud sync over the course of three releases, with dates forth-coming. Each release will take a cautious, well-tested step forward.
Step 1: Re-package your drawings into a new file format that will enable us to support iCloud sync in a future release. This was done in version 5.8 of Concepts, which was released in July. This new file format will also make drawings smaller and save space on your devices.
Step 2: Open the Concepts document folder to the iOS Files app. This will allow you to directly access and view your Concepts files inside the Files app, as well as rearrange and move files into and out of the Files app from Concepts. We will also support "Open in Place", which will allow you to open your file and edit it in Concepts directly from the Files app. This is planned for version 5.9 of Concepts.
Step 3: Add support for relocating your Concepts projects to iCloud. Projects moved to iCloud will be continuously synced. Pro users (requiring Essentials or subscription) will be able to manage which projects are located in iCloud on a project-by-project basis. Users who have not purchased Essentials or a subscription will have the choice to store all drawings in iCloud or on their local device. This is planned for version 5.10 of Concepts.
Future: Cross-platform compatibility of Concepts drawings - to allow you to work between iOS, Windows and Android - will follow once our Android and Windows platforms have caught up with the features available in iOS. We are making steady progress on this and anticipate this will happen during the first half of 2021.
Thank you for your patience and support!
