Flag is a phone and tablet app that prints your photos and mails them to you, your family or friends, for free. Ad Supported Photo Printing
You can’t hang an iPad on a wall, you can’t mail an iPhone in a birthday card, and not every friend and relative uses the same social networks you do. That's why we love to print photos.
Unfortunately printing is expensive, often of poor quality, and not as flexible or fun as finishing photos with apps and filters. Flag is an app for iPhone that will change that.
Flag will be beautiful, clean and simple.
Flag’s ‘peekable thumbs’ view addresses the challenge of displaying photos on phones and tablets without compromise or waste. You can see the whole of a portrait or landscape image, without tapping to open it up, by tilting your device. (NB: unlike this animation our test code is buttery smooth).
Flag allows anyone (within the US to start) to print and mail a pack of 20 photos each month for free. You can keep the prints yourself, or send them to the people you love. If you want more than 20 a month you can buy as many as you need.
To make photo printing fun – for the first time by our reckoning – we’ve designed a photo finishing system ready for the 21st century. Museum quality (Giclée) printers, German 220 gram photo paper from sustainable sources, laser cutters, and robots with carbon fiber arms will allow Flag to deliver prints, for free, that are better than any you can pay for today. We want to turn your memories into mementos you can be proud of.
