I have two of these apps, the green and the purple. Everything was ok before iOS8 but now I encounter many issues and the apps refuse to synchronize between iPad and iPhone. I have sent a mail to the support and the support put the blame on iCloud but it is not true because I do not have that kind of issues with other apps like Week calendar or contacts. lumen apps are expensive so I was expecting a better service. I will modify my comments if the issues if fixed.
