Roaming Guard protects you from accidental roaming connections by monitoring your mobile network operator. The app compares your current operator against a customizable MCC/MNC allowlist or denylist. When your phone connects to an unwanted operator, you can choose to either receive a warning notification or — with some limitations — automatically block data traffic. Roaming Guard includes a predefined EU/EEA allowlist, and you can easily create your own custom list that perfectly matches your mobile plan. Regular Android apps cannot completely block data traffic or even disable data roaming. Therefore, this app implements a local, on-device VPN service that drops all traffic routed through the VPN when enabled. However, this approach has the following technical limitations: - Android only supports one active VPN at a time, meaning conflicts may arise if you use another VPN app. - Tethering and mobile hotspot traffic is not routed through the VPN by Android and therefore cannot be blocked. - System apps that can explicitly select their network connection may bypass the VPN. - DNS and NTP traffic have been reported to leak outside the VPN. - There might be short time windows after boot, or when enabling the VPN, where traffic might not be filtered.

Displays a notification with current operator's name and in case of roaming it also shows the original SIM's operator name. If you swipe (dismiss) the notification, a new one will be displayed when a change in the conexion occurs. To remove the service from memory and avoid further notifications, just tap the notification.

Rosarium is a mobile rosary to guide you through every prayer you need. I put the focus on UX as I feel it gets left behind in most rosary-apps I've used so far. The transitions between decades is animated, you can hot-switch between languages and progressing through the beads by tapping is visualized as well. Languages supported so far: - German - English - Latin - Slovenian - French - Dutch - Portuguese If yours is missing, feel free to open a PR ;) The holy mysteries are date-aware and should show the correct one depending on day-of-week and season. If it doesn't that's a bug, please let me know. Here's a small summary Sunday - Glorious Monday - Joyful Tuesday - Sorrowful Wednesday - Glorious Thursday - Luminous Friday - Sorrowful Saturday - Joyful Sundays in Lent - Sorrowful Sundays in Advent - Joyful There are quite a few interpretations which prayers should be in the rosary so I decided to include more rather than less. If you prefer not to pray the Fatima prayer (you should pray it) or the Hail Holy Queen you can just toggle them in the settings.

This is a very simple app helping christian users to pray the Rosary. It basically shows biblical texts for the mysteries in an ordered way, and simulate beads to count Hail Mary prayers.
