AppNoose's Interval Trainer GO CALORIE health and fitness app is an interval trainer that includes the company's Active Calorie Monitor that allows users to create their workout based on the calories they want to expend. The app will then automatically set the total exercise time. It is also the first to feature in-app dual music playlists, which allows the user to easily and quickly select their slow or fast tunes.
From the start, the app is very easy to use. It features a large dial that takes over the upper half of the screen, which makes it simple to jump straight into the user's exercise after setting up their intervals and playlists. After those are setup the user need only to come back to the timer page and tap the dial to start. Tapping it again pauses and a double tap resets.
As for setup, the settings tab includes three dials, including session length ranging from two to 90 minutes, interval ranging from 10 to 60 seconds and ratios 1:1, 2:1 and 3:1. For those who are not familiar with ratios, the basic concept, developed by Dr. Izumi Tabata, is that the greatest benefits of training come from exercising at a high-intensity close to 100 percent effort for short periods and then following them up with short rests. So, if the user were to sprint for 20 seconds and then rest for 10 seconds, this would create a 30 second interval or a 2:1 interval ratio. This is an extremely useful feature.
Upon launching the app users are prompted to upgrade to version 1.4 premium for $.99, which adds higher ratio options, beep prompts for interval changes, and an end of workout audio prompt. And if they don't upgrade, the popup will continue to appear every time the app is launched. It's just a tap to the next screen, but it's still off-putting. Without the upgrade, the app still offers plenty of useful features.
As a marathon runner and newbie to the hiking scene with a summit attempt coming up for Mt. Rainier, I'd have to say that Interval Trainer GO CALORIE makes interval training less complicated and gives users a great tool for optimum cardio performance.
