Write an iPhone application

Hello Freelancer! We want you to develop an Android app, and if possible iOS. For the app we need a simple webist, like snapchat website really basic. We have already had some developers in Denmark to make a prototype for us on Android, so we know it is possible. The app has 4 main features: 1. We want an app, that can block/ignore all incoming phonecalls/texts/apps (messenger, whatsapp). 1a. We want to be able to set up the blocking in a timeframe eg. 12:00-13:00 1b. We want to be able to activate the app, and turn it of again when it isnt needed anymore. 2. The possibilty for a whitelist, so i can say x can call even tough i activated the block/ignore feature. 3. When i have activated the block/ignore feature, it has to send a text to the one who is trying to get in contact with the app user: 3a. If you activate 1a, we want a standard text like "I will first be available at x" when the app turns of again 3b. if you activate 1b, we want a standard text like "Im not available right now, but will return to you as soon as possible" 3c. A text you can write yourself 4. We want the app to be able to get data from the calender, so if you enable it, it can activate it self if you have a schedule. If this is a job for you, i can specify further. Best regards, Frederik Bøttger
