2025-07-07 00:00:00 Dear user, Unfortunately the platform that this app was originally built on is no longer updated and we've been unable to make the app compatible with the latest versions of Android. We have started working on a completely renewed app from scratch. We estimate the launch of the new app to be in July 2023. In the meantime we suggest you use the Zellr web interface that has recently been optimized for even better mobile experience.
