Aim Straight helps you hold your iPhone or iPad straight while taking pictures, like a bubble level.

Tilt your device until the grid lines turn green. Then take your photo.

The photos you take get added to your photo library. You can see them using the Photos app.

Aim Straight does not upload your photos. But if you have set up your device to upload photos from your library, for example to iCloud, then they will upload the same way as any other photo you take.
