The world has been talking about going paperless over the last few years in an attempt to reduce the strain that we are placing on the environment with all of our waste. Recycling efforts have helped reduce environmental damage but thanks to the simple but effective Paperless app, iPhone and iPod touch users can now do their bit to help save the planet and reduce personal clutter in the process. Paperless is intended to allow us to scan and save receipts in one central location, which means users don't need to carry wallets full of paper-based proof around with them.
