Workhours app - Google play store - NO BIDS except from MAK ONLINE SOLUTIONS -- 2

This app is for MAK Online Solutions i Need no bids from other programmers - Create / ajust my account "google play" - Change the pictures in the app (when you install the app that shows how the app worcks) i will deliver this pictures. - Make a introduction for the "google play" - Setup the app of google play that you have to pay every month a amount to use the app. - Put in the top of the screen (app) the version number "2.5" - When you take in the app "..." - "Guide" you get to see a PDF file that i deliver - When you tahe in the app "..." - "Info" you get a page in the app where is the version number - production date - contact info (email) - and a small text that i deliver. - trail that you can trie it for 1 week free and then it stops working - add in a code to use it for free ? (so by installing when you have this code (hard code) you do not have to pay ... cause then i do not have to pay for testing .... now i test on a lot of phones and then i do not have to pay for the app like this for my testing. (and for the company that i work for)) - When it is on the app store and we do a next update the app store come and tell the user that there is a update and he then do the update without uninstalling and installing again (just like when there is a update for whatsapp you do not have to do somthing it just updates with the phone) Some Explanaition : i do not know if you have to change somhing on the app to check iff it is payed ore to stop worcking iff you do not pay... With many apps you have to pay (google app store) every month , whithout payment you usualy can use the app for +/- 2 weeks trail version ... if you not pay after the 2 weeks the app stops working . if you buy the app and you do not pay the next month the app stops working after a few time asking to pay ... i want them to pay every month for everey installed app , they have to use there own dropbox and they can make as many users they want but every android divice they use have to pay every month they want to use the app. Example : User X finds the app on the app store - User X uses the app trail for 2 weeks - after 2 weeks User X app stops working - User X payes for the app (3,99€) and start using the app on the smarthone . User X want to install the same app on his Tablet he have to pay (3,99€) Now he can use the app 1 month on 2 divices and he payed (7,98€). on this divices he can make more users without extra payment ... After 1 month he have to pay again (3,99€) for every divice he want to use in the next month. Example 2 : Firma Morel : We have 13 carpenters Tim, Kristof,Marc , Arne , Rafal have a individual Smartphone from work Bart + Joren Use 1 Tablet with 2 persons Henk + Arno Use 1 smartphone with 2 persons Laurent +Philip use 1 smartphone with 2 persons Darec + Pjotrec use 1 tablet with 2 persons This means 9 divices have to install the app : if we ask 3,99€/month for the app Firma Morel have to pay 35,91€ every month to use the app and they use it with 13 users.
