On top of development I'm also a capable designer having created designs for 2 commercial iOS applications.
Journey iPhone App
Journey was a design targeted at providing a safety net for individuals as the travel home for the night. Using GPS you would mark the start of your journey and link it to public transport, then when you're safely on your way you would check-in to say you're ok. If you don't within a set period of time your safetyNet contact is notified with your last known position.
The second application I've recently design is one aimed at the health market. The ask was to design something that when connected to your health records would allow you to see important data, alerts and upcoming appointments. It would also act as an assistant to your physician to give them at-a-glance details of your physical wellbeing.
