What i need from you at this point is to give me an approximate cost. To help you estimate a cost: 1. The application will be used to make members to our Association. To certify that is a real person, we need application to send via SMS the access code to the mobile of the member. 2. The person must pay his/her membership via app store / Google. This means: a. The person install the App. b. The app is FREE, but most of the functions will be locked. When someone decides to be a member, must pay via app store and "unlock" the application. c. The cost of the application it will be 100USD (do you know how much we must pay to Apple/Google as commission?) d. I must be able to send notifications to our members (to their application) and to react (accept/reject) e. We will create another 2 or more applications and this app must have links and promotional messages also for the other two apps. These are the info I can provide you so far. Please, describe, how you are going to do it and the cost.

Hello, I'm an iOS developer building my first app. I need an algorithm to sort through the information that the users will submit to my app and the app's search results will be based on that submitted information. For eg. 10 random users all use the same gym named "UrGym". They want to leave a review about the gym on my app. They use the google address api to upload the address information so it all matches. However when they go to submit the gym name some users submit the name YourGym, others submit UrGym, and others submit You'reGym. Considering the address name will be the same because of the google api, there ill be 3 different spellings for the gym located at that address. So when other users go to search that that particular gym, multiple names with the same address will show up. I need an algorithm that would sort the gym spelling names based on the users submissions and I would assume the algorithm would take the most common spelling and use it as the correct name to be displayed in the search results. The problem I do see is if 5 users spell it YourGym and 5 other users spell it You'reGym (in which case they're both wrong) how would the algorithm decide which name should be displayed (even 50/50 split between names. Let be clear this is only a sample to get an idea of what I need so it's not a simple matter of cross referencing the names/addresses with google search because for the real application that may or may not even be possible. I am a Swift developer and if possible I would like the algorithm is Swift. If not I can use Objective C and bridging headers to implement the code. If neither Swift nor Obj-C is possible then C or C++ is also an option as I can find someone to transfer the code over. Thank you

Feely App is a dating app which allows people to meet new people through music. We are two founders from University College London who are deeply passionate about music. We have decided to build a dating app which would connect users through their music taste. We have decided to start with building an MVP and test it before improving on our idea. The basic MVP (Minimum Viable Product) will include users to be able to log in with their Spotify Accounts and match with other users which have most mutual songs with them. So the user experience would be 1. Logging into Spotify Account 2. Retrieving playlist and songs. 3. Matching with the user with most mutual songs. (The next match would be the other second user with most mutual songs) 4. Enabling them to chat. Spotify API is avaliable and already being used by a dating app 'Happn'. We need this MVP to be done in IOS. Skills needed: IOS Development, Objective C, Swift and knowledge with APIs. We already have the UX/UI ready. Website: www.feely.fm
