Hello,
I have gone through the post and as per your requirements i will help you to build an iOs and Android App to change the location. I have developed more than 200+ apps on play and Apple stores you may check portfolio i have experienced in similar apps development.
I have worked on the location tracking apps before for taxi, restaurants and many other apps. I can make the apps as per your need.
I am experienced in apps development compatible with all the OS version. I will start working with designing part and i will make the screens for you and send you for approval. Login, Sign up using face-book, Instagram and directed on home page. I will keep adding the features with the flow you will provide and i will help you to publish the app on the play and apple stores.
Web back-end APIs : I will develop the web admin from where you can control everything using the Web APIs linking with the mobile apps.
Can we discuss about the features now?
Looking forward to hear from you soon.
Thanks
