Hello, i want a simple android application. I can also buy an existing source code if its available from old job you made. I know that there are apps out there that do the same think with a lot more advance features. What i was thinking is: Users after login will be able to create a group or join an a existing group that others have created. To joining a group users will require to know the password that the owner has set or send a request to group owner. Users will see a list of the groups that they are members and also they will see all the members of the group. There will be a ckeckin button . There will be a map in which you will be able to see were is each member of the group and the last time he had clicked checking to the group. I am looking for the lowest price possible. We can remove some features or make changes if this will reduce the price. Its for a school project.
