Can someone recommend a good, free and easy to use service (web or windows app) for mobile apps prototype, mockups, etc. I want to create a visually rich and possibly clickable prototype for a mobile app idea before development.

Hello guys, mom just got an iPhone 8 from a friend who lives in the US and it seems it's network locked as no Nigerian sim card works. What are my options in removing this lock?

Hello!. I have a little tech app idea I'll love to startup. I made an educated guess that my target users are mostly on the android platform. At least 70-80%.Now I don't have funds to get a development team and I want to keep the expenses to the barest minimum. I have a little tech background. I have, used html, css, c# in the past. I always hated Java in school. But it seems I have to embrace it or Kotlin for the development of the app. I want to be able to build at least the MVP and try to gain traction. I am also thinking about cross platform options to cater for both Android and the few iOS users we may have. React Native and Flutter comes to mind. I also think I can get someone highly technical than myself as a co-founder to help. I will appreciate it if you can drop your 2 cents.
