In 2012 young tech entrepreneurs Jon and Anna Bollinger joined forces with established local business owners Neill Birchenall and Phil Howden to form Appt. Appt is a Sheffield based digital agency specialising in the design and development of bespoke mobile and web based apps. The team at Appt love applying their techy brains to help companies: make what they’re doing more efficient, connect with a wider audience and make their creative app ideas a reality.
