iOS, Android, Backend

In 2015, Showoff won the tender process to design & develop the safefood weight-mate system.

Safefood is an all-island implementation body set up under the British-Irish Agreement with a general remit to promote awareness and knowledge of food safety and nutrition issues on the island of Ireland.

Safefood activities include:

  • Promotion of food safety

  • Research into food safety

  • Communication of nutritional advice

  • Promotion of scientific co-operation and laboratory linkages

  • Provide independent scientific advice

  • Deliver consumer focused review


  • To create native iPhone & Android phone applications which provide support for users to lose 10% of their body weight responsibly if they were overweight based off in app calculations provided by safefood nutritionists.

  • To develop a nutrition calculation system that would allow for di erent user demographics and dietary requirements.

  • To protect safefood weigh-mates customers data but also reflect their activity accurately & anonymously.

  • To provide safefood with a scalable solution to deal with national and cross border traffic and to ensure consistency in the availability of weight-mate even under heavy user loads.


Using feedback from multiple focus groups and analysis, we compiled both a full technical and design specification for safefood. This was based off their requirements, the focus groups and what we recommend as the best solution.

  • We produced native iPhone & Android apps all serviced by a Ruby on Rails backend hosted on Heroku.

  • The developed solution provided secure storage for user’s data taking into account privacy policies and security audits.

We love a challenge and working
with the best, so get in touch.
