Hi , Greetings. I have checked your apk and PDF file as well. I have gone through your current calculator app and understood it. I have also checked all your new features for this app. I have some doubt in your PDF : 1) As you have mentioned that color preference will be based from setting menu. In current app we can select only 1 color for theme. But new calculator design has 2 colors(Green and white). So do we have to give 2 color selection option in setting ? 2) How we can get the solution from current calculation ? (Is there any algorithm implemented in current app ?) I am asking because you have shows step by step answer in solution page. - We have vast range of phones for app testing. We have pixel 2 XL , Moto g4 , g5 , g2 , Mi , Lenovo with different android OS in all phones. So app will be passed from all of these phones before we deliver apk to you. - Yes we will keep in mind that existing user can easily update new app without any crash. - We have experienced with admob integration. So we can do this tasks. - We are ready with 300$ budget. Our Work Process: 1. Requirement Understanding 2. Brainstorming 3. Pen-paper mock-up 4. Prototype 5. Development 6. Testing Looking forward to discuss more with you in chat. Thanks, Rushank
