Type 1 App needed

I am a long term member of the diabetes club but have a question. I am looking for an iPhone app that will provide me with the quantity of insulin I need and then store date/time - BGL - Foods taken - CHO - insulin required - insulin taken both BASAL and BOLUS. I used to have an App that done some of these but I bought it in USA and now find it has been taken off of the Apple site.
Being silly if the app could also provide me with food data, the Calories & Carbs app would ideal, give me BGL without finger pricking and make me a nice cup of tea at the same time then that would be very nice.
At present I have to carry round lots of stuff for pricking and testing, and a laptop to provide me with the calculation and storage, and its inconvenient and heavy.
Thanks all.

Thanks for getting back - what do you use to calculate the dosage?

As I said before - I am looking for an iPhone app that will provide me with the quantity of insulin I need and then store date/time - BGL - Foods taken - CHO - insulin required - insulin taken both BASAL and BOLUS.

Sorry for the delay but has that helped you complete your App?
