I remade the iOS version application from scratch in native (Swift).
It's lighter, faster, and consumes less battery and memory than before.
-Improved the UI. It is now displayed at a resolution that better fits the device.
- Supported the multitasking function of iPad (split screen and picture in picture).
- When opening the app from a push notification, the corresponding received mail will now be opened.
・Improved to open SafariTab in the app when calling the browser.
- Supported landscape screen on all devices.
- You can now directly access the device's settings menu from QuickAction or menu.
- iCloud Keychain is now supported, allowing users to remain logged in even if the app is uninstalled, and tokens are now more strongly protected than before.
- Discreet ads are now even more discreet.
・Improved behavior when out of service area or poor connection.
