How much data does Racefully use? – Racefully Help Centre

When Racefully's not recording activities, it only uses data for the screens you load - usually a small number of MB or what you'd load visiting the same number of web pages in the phone browser
When it's tracking a solo activity or one against a previous recording it doesn't use any data
When you are tracking an activity live against other people, it uses around 4 MB per hour or about 25% of the equivalent time on an internet call like Skype
When you use Walk & Talk, the data use is around 20MB per hour or about 25% more than the equivalent time on an internet call like Skype
