BMI Calculator: One of Many Helpful Apps to Remind us of Fitness Levels
By Graham K. Rogers
The TV item moved on to the idea of a healthy weight and Body Mass Index (BMI) with a couple of demonstrations, with presenters entering their own data into an onscreen calculator. A quick look on the Apple Store found me a couple of these and I downloaded the basic, BMI Calculator.
Units are available in Metric or Imperial. As well as inches, users may also select +ft to enter height in Feet and Inches, while weight units include Kg, Lbs and Stones.
I had just weighed myself the day before, so entered that data in Kg, along with my height, age and gender, then pressed the Calculate BMI button beneath. As I expected, the BMI index shown was higher than it should be and displayed a terse, "Overweight" message.
At the bottom of the main screen are icons to other parts of the app: Settings, Graph and Information. Settings allows the user to set default units. Here I found that length (it should be height) was wrongly spelled. The graph section was a nicely coloured screen, but as I have only made one calculation at this stage, there is only a single data point, so no graph appears. A button at the bottom of the screen allows a user to clear all data.
The app was developed by Data Supply who also have a number of other related apps for download. While I was pleased with the ease that I was able to calculate the BMI, providing me with a much-needed reminder, I was disappointed with the poor spelling.
The developers are from the Netherlands and the Dutch are known for good English skills. I know I am an English teacher so perhaps focus on these problems, but there is no real excuse: a check would fix these minor problems. Failing to make the check, leaves the app looking shoddy.
Nonetheless, this is a useful app because of the reminder it implicitly contains to those of us whose lifestyles (cakes and ale in my case) may need some adjustment. There are other apps in the iTunes App Store with a similar purpose, many of which will help us use the data with other health apps appearing on our devices.
