Heartie - Smart Intervals
Smart Heart Intervals
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
“Ever wondered how much you should increase your workout intensity? Now your heart rate can tell you.”
Hello, this is Heartie. :)
I don’t believe that being good at exercise means simply enduring longer or pushing yourself harder no matter what.
Some days, your heart rate rises quickly even with a light run.
Other days, your body keeps up well even when you move a little harder.
Workout intensity can change every day.
Your condition, fatigue level, and recovery state are different each time.
But!
It’s often hard to tell by feeling alone whether you are pushing too hard or whether it’s okay to raise the intensity a little more.
Heartie was created for exactly those moments.
Based on your heart rate, Heartie helps you set the right interval workout intensity for your body and stay within the appropriate range during exercise.
So, go ahead and start!
- Key Features of Heartie
1. Heart Rate-Based Workouts That Fit Your Body
Adjust your workout intensity based on how you feel today.
Heartie is not about exercising as hard as possible. It is about training smarter according to your heart rate.
2. Create Your Own Interval Routine
Set your high-intensity intervals, recovery intervals, and number of repetitions.
Instead of following a fixed workout, you can create a routine that fits your goals and fitness level.
3. Heart Rate Zone Alerts
When you move outside your target heart rate zone during a workout, Heartie notifies you with sound and haptics.
Reduce overpacing and maintain the right intensity without becoming too relaxed.
4. Keep a Record of Today’s Workout
Check your workout records by date and look back on what intensity you trained at and how long you maintained it.
5. Grow Consistently Without Overdoing It
Exercise is not about pushing yourself all at once.
What matters is repeating workouts at an intensity that fits your body.
Heartie helps make your daily workouts safer and clearer.
