A new, free edition of 4th at Square is now available in the Windows Store. 4th at Square Lite shares the same codebase as the paid version and the same feature set, with the following differences:
- Does not support background updates to the live tile.
- (It will still update when you check-in or view the Friends page)
- Does not support notifications (i.e. check-in reminders, or nearby friends).
- Contains advertising.
- Contains “nag text” at the bottom inviting you to install the paid version.
My plan is to keep both versions in sync for all future updates. However, it is possible that additional features may be added to the paid version which won’t appear in the free one. This is particularly true for future updates which will make use of a server back-end (i.e. notifications whenever a friend checks in, and live tile updates for pinned locations or friends).
