Ok I need a great developer 'company' (sorry no single freelancers) to take over a project. Also and only those with extensive experience with GPS 'handheld device' tracking should respond, and further have overcome the tracking side of it with the app going 'Offline' which from what I am told is the OS shutting down the app and on both the ios and Android side. DO YOU HAVE A SOLUTION TO THIS? I have attached a pretty good description of what is going on here including some tracking tweaks and other things that need to be done. But the 'Offline' problem is the biggie, which needs to be figured out. So please include a price to fix these items along with you bio of your experience and samples in this field. Please also put 'GPS' at the top of your response so I can eliminate all the auto/spam responses that have not read this entire posting. The backend is writtien in codeigniter/PHP, the Android side is in Android Java and the ios is in Native. An NDA will also be required and please allow me a few days to make a decision. Thanks!

GPS Hi, We have reviewed your requirement for those issues. Point 1 can not be assured as sometimes phones GPS gets the wrong location [depends on different conditions like area does not have that level of data, accuracy issue , wrong lat/lng] so this can be optimized a bit but not 100 corrected. Rest of the points can be reviewed and fixed. To get started we will need source code access to review so that we can get estimate of time/cost required to fix your code. So only after that we can help you. Please send NDA or setup NDA on this project and we will get it singed. We have worked on something similar app for local authority so we can help you well on this project. We have experienced team for android, ios and CI/LARAVEL [LAMP stack] Look forward to work with you. Thank You, CWE
