Mrs Reid said the idea for GroPrint came after she made a messy and unsuccessful attempt at making prints of her sons� hands and feet using paint and paper.
�Like every new mum, I wanted to capture each moment of my babies� development,� she said.
�I really liked the idea of watching my boys grow through their hand and footprints but the reality of doing this every few weeks was very messy.
�I was surprised to find there wasn�t an app available to easily capture hand and footprints given we use technology for everything else.�
To use GroPrint, a child puts their hand or foot on the outline on the iPhone or iPad screen and within seconds, an actual-size image is created.
�I thought I�d have problems getting my kids to sit still but it�s so quick and easy to use that they treat it as a game,� Mrs Reid said.
The images can be saved to use on social media, print or to create personalised products.
