Turn your iPhone into a fully functioning activity and fitnesstracking device
This is the story of how I turned my iPhone 5 into a fully functional activity and fitness tracker.
This years biggest and most exciting techbuzz has been the rising popularity of wearable technology. Although the term wearable technology has a very broad meaning, recently it has focused mainly on activity tracking and fitness tracking.

Wearable devices like the Nike fuelband, Fitbit Flex, and Jawbone Up are growing in popularity mainly for its ability to track ones activity and monitor fitness. I have long wanted to try one of them out but I had a hard time deciding which one to pick. I read a lot of reviews on all three of them and the reviews are mixed. I researched their specs and features more and found that taken individually, each one seemed to lack something the other was offering. Take for example the ability to track activity and monitor/update calorie in-take and budget. Say I go for a run and burn a certain amount of calories, I want my calorie budget to be updated right away based on the recent activity and the food I took so far. Both the Jawbone Up and Fitbitflex have application support to log food intake however logging food intake is not very convenient for both. Both of them have mobile applications that support logging calorie in-take however it does not provide live update of your calorie budget based on your activity. For the Fitbitflex you have to wait until your bracelet has synched with your desktop app to calculate your net Calorie intake for the day. Not one of these fitness bracelet supports integration and live updates. After days of researching I ended up frustrated. Not one bracelet met my needs and I sure as hell was not going to buy all three of them. Then I had a light bulb moment- why not customize my iPhone 5 into the kind of activity/fitness tracking device I want through Apps.
Before I tell you how I did this, let me share with you first what I consider as essential features to any activity/ fitness tracking device:
1. Run logger w/ GPS and live feedback
- I need live feedback of my run progress (ie. distance and pace)
- I need GPS tracking to map my route because when I discover a nice running route I want to be able to remember where to got.
- I need it to have access to my music library
2. Location aware Pedometer
- I want to know how many steps I took each day
- I want it to be location aware so that I know where and when I am most inactive.
3. Calorie tracker
- Ask every nutritionist and fitness coach and they will tell you the food you eat affects your overall fitness level.
- I want to know how much carbohydrates, fat and protein I am taking eachday.
4. Sleep Cycle tracker
- I need to know if I am taking enough quality sleep each day. The amount and quality of sleep I take each day is as important as the amount and quality of activity I do.
5. Integration
- I want the information I track to understand how they affect each other. (ie. calories burned during a run should update my calorie budget for the day.)
Here is a run-down of how I turned my iPhone 5 into a fully functional activity/ fitness tracker.
The Applications.


3. Myfitnesspal: this is my calorie counter/budget app. It allows me to keep track of my daily calorie in-take and set a daily calorie budget to achieve a desired weight goal. Aside from just counting your calories, the app breaks down the calories into Carbohydrates, Proteins and Fats. This is very important information for people trying to maintain a certain diet. I do a lot of running and I know I need a lot of Carbohydrates to sustain my runs. This app allows me to set a meal plan that has the right amount of carbs, protein and fat. I am able to do this with the apps Recipe feature where I can set specific meals I prepare at the beginning of the week. The app also supports bar-code scanning for most pre-packed food items. Just scan the barcode and the relevant dietary information is on your screen. Last, but not the least, the app integrates with 3rd party apps that are health and fitness focused. In my case it integrates with Runkeeper and my Runtastic Road bike. This means after every run or bike session, the calories burned are updated into my daily calorie budget. This is both convenient and smart.


For now I am happy to say that I was able to build and customize my own fitness and activity tracking system using my iPhone 5. The total cost to me? Less than $10 for all the apps. Not bad compared to a fitness bracelet that runs upward $100 each with features that do not necessarily fit your needs.
