I need an Android app. I would like it designed and built though see a preliminary design attached.
phone app (iphone and android) to store and share item information.
should be a searchable database: item can be identified by names or id number
more information such as field like pictures, pdfs, texts can be added to the item information
opening the app requires a 4 digit security pin number
a specific item can have its folder of information shared by email to someone else who owns our app but with a password to open the file
can write a simple text file for each item within the app
should be able to create a backupfile to download on their computers or by email (password protect)
should be able to store a few thousand items
should be able to delete items or information stored in their folder (ie the pdf)
for example the user will create a new item which is a car named voltron with id number 12345678
within this items folder they can create a new field called photo and attach a photo on their phone gallery. then they might add a text file with some description.
the next item they add is a flower called rose with item number 11223344 and then they create a field called photo and add a photo, then they add a field called pdf and attach a pdf file with the flowers description.
the opening page after password login would list the items so far (rose and voltron, each with a visible id number and if possible a creation date and a last accessed date)
no cloud use. data should be stored on the phone and backed up to SIM card or PC.
