  The Prechtl General Movements Assessment (GMA) has become a clinician and
researcher tool-box for evaluating neurodevelopment in early infancy. Given it
involves observation of infant movements from video recordings, utilising
smartphone applications to obtain these recordings seems like the natural
progression for the field. In this review, we look back on the development of
apps for acquiring general movement videos, describe the application and
research studies of available apps, and discuss future directions of mobile
solutions and their usability in research and clinical practice. We emphasise
the importance of understanding the background that has led to these
developments while introducing new technologies, including the barriers and
facilitators along the pathway. The GMApp and Baby Moves App were the first
ones developed to increase accessibility of the GMA, with two further apps,
NeuroMotion and InMotion, designed since. The Baby Moves app has been applied
most frequently. For the mobile future of GMA, we advocate collaboration to
boost the field's progression and to reduce research waste. We propose future
collaborative solutions including standardisation of cross-sites data
collection, adaption to local context and privacy laws, employment of user
feedback, and sustainable IT structures enabling continuous software updating.
