I like being able make changes, add new dogs easily without having my computer open at home so that if anything happens it is easier for me as an owner/breeder not worry about getting into emailing etc when away with clients! Also i really dislike how slow everything seems compared other apps out there but maybe this makes more sense because of its purpose which was designed by breed club members themselves? Maybe they just need time before features are added?? Very easy once you get used too!! The fact we could see our own dog's progress day after next (and update them!). And also seeing what their mum did during pregnancy helped us understand better. It does go back months sometimes making updates difficult until someone else has logged onto her account first then updated hers - annoying for both parties involved unless she realises herself lol?! Great tool though great app overall. We use AppyBreed.
