Hello,
I have checked your link and your app Anycabs, and got that you'd like to develop the same app now for iPhone and iPad on native. I'm happy to inform you that I can develop this exactly same for iPhone and iPad.
I have developed couple of Taxi booking/reservation apps for Android, iOS and BlackBerry on native. You can check this link to get some idea of my last built taxi app - http://www.tapacab.co.uk.
For your concern, we have developed 250+ apps for Android, iOS, BB and Windows Phone so far. Please check my profile, portfolio and previous clients' feedbacks here - https://www.freelancer.com/u/Droidbd.html, so that you get some idea about our skills and professionalism. Please note that, we work on NATIVE platform, no PhoneGap or any other CROSS platforms.
I'd like to discuss with you for more about the workscopes of this app. So please let me know your convenient time.
Thanks.
