Redesign our apps

Hi, Important: I have taken a lot of time to write all possible details for you. Please do respond accordingly. Incomplete and automatic replies will unfortunately be deleted. The app is doing well but it was poorly designed in the beginning and needs a complete makeup. Re-design to make it a welcoming environment for people. The app caters to patients suffering from diabetes, cancer, heart disease etc. so they have enough grief in their lives. Let's give them a ray of sunshine with nicely laid out complementing colors, pretty graphics and an overall experience that makes them want to come back. Here are the details: Current App: ios and Android ([login to view URL] to see download links). Link to original designs: [login to view URL] New additions needed: 1. Facebook/Google login integration 2. "Hugs", "Like" and "I'm with you" buttons 3. A couple more things perhaps. Please keep in mind I am looking for an expert in this who knows how to entice people with colors, how to match sections perfectly for viewers, and how to make the entire software flow cohesively and smoothly. I need 3 samples of apps (both ios and android) that you have done that you feel are the best of your work. If you just send me your behance page, that doesn't tell me much. Please be specific in what you want me to see. It will help both of us. If you really want my attention, give me some idea of what the design would look like. I am going to ask you anyway. I am open to redesigning the whole thing including the logo. Just the name stays. The work is urgent so early and complete response means I will be looking at it promptly. An app I consider very well designed: Ovia fertility. Lastly, this App is completely free and is my way of helping very sick people. So no money is being made on this project. I am happy to pay your fees but if you are considerate and want to help out by reducing your rates a bit (happy to post to my 5000 Linkedin followers), it would be much appreciated. There is also more work in the future that you can count on probably later this year. I have put a budget of $100 just as a filler. Feel free to quote your price. Lastly, this is a fixed bid project. Please don't quote hourly. Thanks
