When you tap the 'photo' in the footer, you can select and upload photos.
If you want to reset the filter, please tap the refresh button in the upper left.
This app is also compatible with landscape view.If you want to edit a photo landscape, you may want to use this mode.
Sorry, this app will not be able to save the edited image. But there is the mode for you to take a screen capture. Please double-tap a photo to start it.
This app supported the standalone mode, of course. If you want to use it, please add to Home Screen.
This is the feature for PC. When you click the Home button on the iPhone that is displayed in the browser, the list is displayed.
