Hi,
I am an experienced iPhone Developer with 10+ apps which involves Social Media (Facebook, google, twitter etc) integration, GPS tracking and navigation apps, Payment gateway integration, integration with contacts and messages, integration with Dropbox, google plus cloud storage, apps with Security password required to enter (passcode or pattern), sign up functioning, referral system etc.
I am proposing the bid and estimated time based on the summary you have mentioned but we can discuss the actual time estimation and costing, once you disclose the complete requirements.
Please find the brief approach. Exact approach can be discussed once you share entire details:
- Login via Social Networking (Facebook, Google, Twitter) or via Sign In with email id
- GPS tracking for Location based features
- Share events/status/pics via facebook, google or twitter
- Analytics integration for tracking
- Custom Categorization based on customer inputs
- Pre defined Categorization
