Project Description



i search a developer who's able to develop a iphone/ipod touch app conforming to apples specification with a working server synchronisation.

it is basically a web-/app-/iphone-solution to sync notes over more than one device with one main mysql-db. the desktop and iphone-app is for offline editing with sync-solution.

data in notes


– date/time of creation

– date/time last modified

– title

– utf-8-text (without formatting max length 4000 chars)



the ipod/iphone-app and the desktop-app must offer an online-update of the client.



the sync must be absolute professional. means: handle deleted entries, handle conflicts during sync, always make sure, that the received datas are fine (hash).



the sync works through a php-webpage on the server. so we can be sure that the user don't have trouble with firewalls etc. the php-page sends the data as a xml-file like:



<data>(zip-compressed data (use zlib))</data>

<hash>hash-value of data-block</hash>




the main-webpage and mysql-db is hosted by [url removed, login to view]



here you can see a layout. pleas note that the gui must be professional. this is just to give an idea.

[url removed, login to view]

develop a c++ application for macos x (with cocoa gui)


in that app you can create hierarchically folders and in the folders notes. the datas are stored in a sqlite-db (source of lib: [url removed, login to view]) in the current users "application support" folder.

the app is a one-windows-app:

- main-window to enter text & titel and on the side a drawer to see the hierarchy.

- on the top of the windows is a search-field and several buttons; new text, new category, delete and show/hide drawer, sync

- also a "slide-thin" to flick through all notes (not the folders)

develop a application for ipod/iphone


same application just with a ipod/iphone-gui.

(there must be a solution to move, edit, del the hierarchy as well as in the desktop app)

develop the webpage


same application just with a web-gui.

(there must be a solution to move, edit, del the hierarchy as well as in the desktop app)

here the customer gets also the username & password for the account. account expires after a jear (--> renew with paypal-transaction)



each application must have following preferences

- sync-url; where the sync-script is (not for the web-app) with a default-value

- user-/password-save for sync

we need the whole source-code of the apps and the web-page. pleas note that we don't offer a webserver and a mysql-server during the tests and dev.

if you get the job we expect a documentation of the synchronisation-steps to see your solution.

i've got just basic c++/php/mysql and english knowledge.
