Heart Rate Zones Plus

Track your time in heart rate zones and reach your fitness goals

Take your fitness tracking to the next level with Heart Rate Zones Plus - designed for people who want to understand their heart rate zone performance, not just count steps or calories. Whether you're a dedicated athlete, a weekend warrior, or just starting your fitness journey, this app helps you monitor your heart rate zones, set meaningful goals, and visualize your progress in ways that matter.

Key features
1. Custom time periods
Understand your overall time per day, week, month, last 7 days, last 10 days or last 30 days in each heart rate zone.

2. Workout to zone attribution
Ever wondered which workouts actually contributed to time in Zone 2 or Zone 5? With the smart breakdowns, you don’t just see your total time in heart rate zones—you see exactly which workouts fueled those stats. This lets you answer questions like:
- Does swimming really push me into higher zones?
- How much time have I spend in Zone 2 this week?

You can also use the simplified aggregates moderate exercise (Zone 1-3) and vigorous exercise (Zone 4-5).

3. Set personal time goals for any zone
Motivation thrives with targets. With customizable goals, you can decide how many minutes you'd like to spend in each zone over a selected time period. Track your progress with sleek, animated bars that make your data easy to read and satisfying to follow.

4. Past Workouts and Days breakdown
Visualize the impact of each workout session and day in intuitive bars, color-coded by zone. This helps you to track, for example, if you really hit it hard two times a week or in your cycling workouts. It can also help you to check that your running is always just in Zone 2.

5. Multiple zone calculation methods
Not all hearts are the same, and neither are their training zones. Choose from a variety of scientifically-backed methods to calculate your maximum heart rate like:
- 220 – age
- 208 – 0.7 × age
Gender-specific formulas, such as:
- 216 – 1.09 × age (bio. female)
- 202 – 0.55 × age (bio. male)

Decide if you want to include resting heart rate into the zone calculation and use the Karvonen method.

You can also manually override your max heart rate and resting heart rate, giving you the power to personalize your training.

6. Setup manual zones
If you know your zones from a lactate measurement done by a sports medicine specialist or just want to mimic Zones of other apps, Heart Rate Zones Plus can do that. Setup with your custom beats per minutes.

7. Privacy
Your health data stays on your device. Nothing is saved or sent. Data is used only to locally calculate metrics.

8. Dark and light mode support
Whether you prefer a sleek dark mode for evening reviews or a crisp light mode during the day, the app respects your visual preferences.

Why this app?
