Hi, I am a developer. This is a small iOS app: you can continuously take a bunch of photos, pick one, click the heart to save it to the album, and the rest will be automatically discarded.

The motivation comes from my frequent sharing of food and scenery with friends, often taking a dozen photos from various angles, but only sending one out in the end, while the rest stay in my album, occupying a huge amount of storage space.
