1 Medication Tracker App for iphone Ryan Hitt CPET 491 Purdue University Fort Wayne Department of Computer, Engineering, and Information Technology 1 Content Background and Introduction Project Management Design Process Legal Aspects Programming Languages Integrated Development Environment (IDE) Software Design & Architecture Demonstration 2 1

2 Background and Introduction Family members and others in my life with diagnosed diseases (Intestinal cancer, Crohn s disease, etc.) Wanted to learn more about these diseases Discovered lots of information, intimidating to keep track of it all Thought I could simply and consolidate some of this information 3 Background and Information Got idea for app from my grandmother Not a fan of technology, but loves her iphone Kept paper charts and writings for all of this information Wanted to give her one place on her phone where she could store all of that information 4 2

3 Background and Information Experience with various programming languages, but never developed for any Apple equipment Never developed a mobile application before Chose iphone because that s what was readily available to me Wanted to make an app simple enough that my grandmother wouldn t have to ask how to use 5 Project Management Went about researching how to make an iphone app Acquired ios SDK for app development Obtained training materials for iphone app development Predicted roughly 350 hours needed split between research, education, and actual development 6 3

6 Design Process Desired iphone app features: Database for diagnoses, medications, workout and diet plans, and physician information Easy-to-use, straightforward Graphical User Interface (GUI) Some features not possible due to legal requirements 11 Legal Aspects Wanted to potentially store my database remotely, so information can be accessed from multiple devices Also wanted to show a list of medications associated with a given diagnosis when that information is entered Wanted to list my app on Apple s App Store Food and Drug Administration (FDA) has the right to regulate and monitor any mobile medical application 12 6

7 Legal Aspects FDA s Mobile Medical Applications Guidance Report lays ground rules for regulations and monitoring: Connect to another device for purposes of controlling or displaying, storing, analyzing, or transmitting patient-specific medical device data. Perform patient-specific analysis and provide patient-specific diagnosis or treatment recommendations. 13 Legal Aspects Even though there is no regulation, my app would still be subject to enforcement discretion by the FDA because my app will: Help users self-manage their diseases or conditions without providing specific treatment or treatment suggestions Provide users with simple tools to organize and track their health information Provide easy access to information related to users' health conditions or treatments 14 7

8 Programming Language ios apps written in Objective-C Object-oriented superset of C, similar to C++ or C# Developed at NeXT, now used for Mac OS X, iphone, and ipad Built on top of C++, can actually use C and C++ code in Objective-C programs Application Programming Interface (API) Cocoa Touch written in Objective-C 15 Programming Language Cocoa Touch API has many different frameworks that make up the package Core Animation WebKit Address Book Core Data SQLite Many more 16 8

9 Xcode IDE Xcode is IDE used for Mac, Safari, and ios development Supports multiple languages (C, C++, Objective-C, Javascript, HTML, CCS, etc.) Integrated GUI editor and database developer Built-in simulator to debug applications without having to load onto a device after every recompile

12 Software Design Wanted app to be simple and easy to navigate Wanted to have a consistent look and feel to the rest of ios so the app didn t feel foreign Navigation of the app modeled after the iphone s own apps, such as Phone and Music

15 Lessons Learned Learning a new programming language with no guidance (classroom, teacher, etc.) is challenging Making a mobile application is not as simple as just writing code Getting a quick handle on proper time management is paramount to any project 29 Works Cited [1] A.
