Any suggestions for free apps, apps particularly directed at ethnographic research (and not marketing) are very much welcome as well as any research papers on the use of diary studies combined with digital ethnography (preferably in Africa) and/ or the use of whatsapp in qualitative research in Africa (I am familiar with https://edoc.unibas.ch/51923/1/20161216110618_5853bc9abba73.pdf)
Thanks!
