SodaSnap offers a simple app interface that matches the simplicity of the final product. To get started, choose an image. You can either select a photo from your iPhone's camera roll, snap a pic of your surroundings, or use your location.
Using your location brings up the maps app from which you can screengrab. This doesn't make the most compelling picture postcard, but it may be a useful tool for meetings and invitations.
Once you're happy with your image, you can add text and hit the "Share" button. The way the app is designed, it's pretty much what you see is what you get, so you'll have a good idea of what the recipient will see in the inbox. As well as email, there are options to share to Twitter and Facebook.
The Photocards app allows you to snap a pic or grab one from your camera roll. When you've sized the photo to fit the frame, you can choose a background.
The available backgrounds display classic stock photography — the sky, greenery, sand, landscapes, etc. — but the pleasant surprise is that the images are actually decent quality. The not-so-pleasant surprise is that you have to pay for some of them.
With your background and picture in place, it's just a matter of penning a few lines before emailing your creation.
Montager is a little different because it acts as more of a photography tool. However, we really like that it lets you get creative with your pics.
It offers a number of templates that allow you juxtapose three images into a mini-montage. You simply double-tap the empty space you want to fill, and then create your triptych either on-the-fly with photos taken with the iPhone's camera, or from pics saved to the camera roll.
Although there's no built-in text options, you can email from within the app, so add your message there.
Once you've snapped a photo or grabbed one from your camera roll, the Current Postcards app lets you select a font (a big bonus in our book) before opening the theme gallery.
Themes categories include Birthday, Special Events, Holidays, Everyday or Just For Fun. While we'd struggle to pick a theme from most of the clipart-esque options, the simple postcard in the "Everyday" category (as seen above) is quite classic.
You can send your Current Postcards creations via email or post to Facebook.
Creating a postcard with the Postino app is a four-step process. First upload a photo from your camera roll or capture one anew with your iPhone.
Next write the message, and then you're onto the really fun step — adding your signature.
You can scrawl your John Hancock on your iPhone screen with your finger. We think this would be a really nice touch if you're sending postcards with a child — although, if your finger writing skills are as rubbish as ours, your signature may end up looking like a child's anyway!
Once you've added that personal touch, email your postcard.
