Looking through your comments I saw that like me you mostly like to use Picasa and PicMonkey although some of you are a bit wary of the chimp!
Riitta is new to mosaic making, she's using Fotor for Mac and queried if Picasa or PicMonkey work with Apple.
A quick google search later and I think the answer's yes. Riitta, if you decide to try them out do let us know.
Other, new to me, app's mentioned were iPiccy; Fotojet; pixirexpress; pizap and photocollage on iPad.
I've not strayed far from home for my collection of mosaics this week.
