The app's format is extremely simple. When you open the app, it opens into a gallery of photos from your camera reel, or a selection of stock photos.
Naturally, the stock photos are devoid of context or explanation, presumably leaving the user free to put their own hilarious spin on them.
You can also take photos from inside the app.
There are around 90 stock photos to choose from. A surprising number of the stock images relate to watermelons, for unclear reasons.
Some of the most wacky stock photos include a man using two toilet rolls as binoculars, a man with a watermelon for a head, a woman holding a carp, two giggling nuns, and a cat owner hissing back at their cat. There are several weird watermelon photos in the selection.
Once you've completed making your meme, Whale encourages you to share it across Facebook's other social networks.
You can also share the edited image across other social networks or messaging apps.
Because the app is connected to Facebook, users are expected to abide by its community standards.
They can share their created memes through Instagram, Messenger and the core Facebook app, as well as through non-Facebook affiliated channels like Twitter, DropBox, and more.
Whale is pretty fun to use and extremely simple, but it joins a crowded ecosystem of social apps.
Whale doesn't offer much more than the image-editing tools you might see on Snapchat or Instagram, which also let you overlay images with colorful text and graphics. Still, Facebook's NPE team is all about shipping products rapidly, and the firm will shut apps down that don't take off. This may just be a neat experiment.
