    I am looking for a iPhone developer that will be willing to make a social networking app. The main point of this app is to post and comment on posts all anonymously From posting a status anonymously, to commenting anonymously. They will be able to make a account with an email set up a username and password and be able to have a picture and biography while viewing their profile. There will be four sections on the top of the iPhone the first is feed, second is Others, third is Activity, and the fourth is Profile. The feed is all the anonymous posts of people you follow and comments. The second thing is activity which is a brief list of things people of your friends list have commented on. The activity is where one can if an anonymous person commented on their post, and also if they are private to control who follows them. and Your profile is your picture, name, and biography it, also below it ONLY shows how many posts and things you commented on, it doesn"t show any posts. When you make an account you must be following at least 10 people to view post to make it as anonymous as possible. You can make yourself private to control who follows you as well. and also to make a script or something to make it so when one posts something to their followers after it will be deleted on the main database so it will not be linked to the person who posted it anywhere. The point is to make it as anonymous as possible. The last thing is to put a small ad at the bottom of the screen while in the feed or others section. This idea is copyrighted by myself so do not try to make this without me.

    I would like an android app that allows people to access their phone"s contacts. Users would select their phone"s contacts and notify those people that of a connection request. If the 2nd user accepts the request through the app, then a connection is made and the two users can access a map (in the app itself) that shows the locations of the people they have connected with for a brief period of time

    This is a social mapping app. The app presents users with their contact list which they can search through with a search bar. The list will draw contacts form the phone’s contact list and the app’s own private contact list. User1 selects contacts that he/she is interested in connecting with. When User1 hits CONNECT, the selected contacts get a notification (if they have the application) that says that User1 would like to connect with them. If receiving useres do not have the application, then they are sent an SMS that links them to the either the Apple app store or Google play store (depending on the platform receiving user is on) to download the app. If receiving users accept the invitation, the two users broadcast their locations to each other for a temporary amount of time. In the app, the users can see a localized map with the locations of the people they have connected with being shown in real-time. Selecting users on the map by clicking the icons representing the user will allow users to SMS.

    The Project- To create a simple, easy to use app for both Android and iOS. - 10-14 days max for completion (does not include approval obviously)- The app is very simple, and will need to look, behave and work the same on both platforms.- Submission to app stores and source code requiredDevelopment and Functionality - see App Brief for more detail in attachmentsDesign- All design work will be handled by our graphic designers so this will not be necessary on your end.- The app needs to look the same, or close to, so your team will need to give us the easiest option in terms of how to handle multiple screen sizes on android, whether that be floating elements or stretching content/screens. - More detailed designs will be given after project is rewardedTimeline- Fully completed, all development for both platforms needs to be finished on or before July 31st 2014, midnight AEST, with all project delivered to our team.Servicing and Maintenance - The app needs to be free from bugs, crashing and other unexpected variations or deviations from what the project specifies.- If the app is found to have issues we expect your team to correct them immediately, and within the costing without extra charge.- We will not seek extra work for free, we are fair. So if there are any new features we would like the app to do we can arrange a fee on top of the old feeAny questions please ask

    Il progetto consiste di creare un sito web ed una app sia con sistema Android che IOS. All’interno della APP ci dovranno essere 4/5 sezioni di scelta di facilissima intuizione. Due sezioni dovranno essere dedicate alle prenotazioni; una persona che scarica la App sceglie la voce che gli interessa e poi prenota scegliendo il sistema in automatico che gli offre l’App oppure cliccando sul numero verde e si collega con una centrale e sarà un operatore a prenotare per lui. I fornitori con cui prenotare saranno dislocati in tutta Italia e saranno composti da persone o aziende che svolgono i più disparati mestieri. Come dicevo sopra chi non è in grado di prenotare dovrà avere la possibilità di completare l’operazione anche tramite numero verde che sarà successivamente attivato.Le altre sezioni dell’App saranno decise successivamente in quanto indecisi su alcune tematiche.All’interno della stessa dovrà essere istallato un calendario in modo che l’appuntamento comunicato successivamente dagli operatori, tramite sms o mail, vada ad inserirsi in automatico anche nel calendario.Io non sono un esperto perciò vi chiedo la cortesia di consigliarmi in modo da scegliere la strada migliore per realizzare il progetto.Volevo rappresentare un ostacolo, se così si può chiamare, di non poca importanza che è: durante l’anno ci arriveranno dai vari fornitori di opera che saranno inseriti nell’APP molti aggiornamenti di dati. A tal proposito è possibile pensare ad una App visto che richiede molti aggiornamenti? Tale situazione può creare problemi con gli store di ambedue i sistemi operativi?Comprendo che esplicitato così non si capisca tanto bene ma se volete potete contattarmi tramite mail.Grazie e a presto.Antonio
