The next release of ChurchInfo will include features for self-service usage by individual members. This feature can be used with an existing ChurchInfo database or it may be used to start an entirely new database directly from the congregation. You can see a preview of the new self-service feature in this video.
The current release of ChurchInfo 1.2.14 is not compatible with PHP 7 but this next release will be. Current releases of ChurchInfo use a database library that has been removed from PHP 7.0.0.
