I really dont think that an app like this can replace the actuall caring of a mother towards her child. I did tried this app but I dont find it useful and if I found any delay in the development of my child, I would rather consult a Child Specialist.
Every living being monitored their childrean and it is in their nature to do so. Humans are intelligent enough to take care of their child without the use of any app and I dont think Animals were ever in need of this app. Your child is your responsibility, don let any pre-programed software to interfere in between it.
To help you track your child, this app asks you some question like- Did the child raise itself to sitting position, did the child roll over the stomach and few more. And it gives you a list of some Doctors to book and visit. Thats all it has.
There isnt any need to download this app.
Thanks to the developer for giving it a try.
