Dear Eva,
We are waiting impatiently! ;-)
And second remark: you are working on the original MARS from 2015 and not on the User Version (Stoyanov et al. (2016): Development and Validation of the User Version of the Mobile Application Rating Scale (uMARS) JMIR Mhealth Uhealth 4(2): e72), isn't it!?
Regards,
Mario
