This is a simple app which lets you create a list of items for grocery shopping. There are 3 tabs on the main screen. The first tab, named Active, shows the currently active items, the ones which have not been checked. The Completed tab lists all the items which have been checked and the All tab lists all items.
To add an item just tap on the plus button in the upper right, enter a name of the item and, optional, a re-appear time and an image. Reappear means that a checked item will be re-activated after the chosen time and appear in the Active list. You can attach an image to the item by selecting one from the Photo App or by snapping one with the Camera App.
An item in the Active tab can be checked by swiping it to the right and tap the blue check button. It will then be moved from the Active to the Completed tab. Swiping an item in the Completed tab to the right and tap the clock button will re-activate it. By tapping the yellow edit button you can edit the selected item. Swiping to the left will delete the item.
The display button with the lock, in the upper left, prevents the iPhone from going to sleep. After you tap the button the icon will change from blue to red and shows a closed lock. As long as the app is active the iPhone will not go to sleep. Tapping it again will reactivate iPhone sleep.
