The best part of this app is its simplicity to use, it has all you need in one place! It's very easy once set up correctly - no complicated features or confusing menus like other apps I've used before (like Church Manager). Some things are missing from their website but not enough as far we can tell so don't worry too much about those issues if they aren’t important/important at least yet because there will be updates soon which should fix them eventually :) For us right now everything works great except syncing our address book contacts between phones & tablets via iCloud since some people have different numbers than others depending where someone lives etc.. This isn't really an issue though just something worth mentioning here ;) We're using CCCH primarily during worship services when members might leave early without calling ahead first instead having everyone get together after service ends then waiting.
