Knowing your current heart rate is useful, but seeing in real time how it varies over a longer period tells you much more, especially when you want to understand how your body is responding to a training plan. Heart Graph suits all types of aerobic exercise including running, cycling, rowing or gym work, or everyday heart rate monitoring for general health. Heart Graph records new data and shows your heart rate graph in real time, and also imports existing data from Apple Health. Compare previous sessions to see how your body is changing over time: directly compare the graphs of equivalent sessions, view statistics such as max, mean and resting heart rate across sessions, or see the time spent in each heart rate zone aggregated over weeks or months. (Note some features require a one-off In-App Purchase, as described below.) FREE features of Heart Graph include: * Display a real-time graph of heart rate against time on your iPhone or iPad * Support for Bluetooth sensors, Apple Watch and AirPods * No ads * Review your sessions offline to spot trends in your data * Integration with Apple Health: import existing workout data or a chosen time period of up to 24 hours, and store new workouts * Maximise the graph area on iPhone using landscape orientation * Group related sessions with your own notes, then search for sessions matching those notes * Record a standard Reference Set at the start of each session to see how your body is really doing; if your heart rate is elevated, take it easy * Record data in the background if you want to use other heart rate apps (Bluetooth sensors) * Calculate calories burned, and set a calorie target for each session Beyond the basics, a single, one-off In-App Purchase enables the Premium Features: more in-depth analysis tools and the ability to design your training sessions in the app. Planned Workouts split a session into small pieces, for example sets at the gym or intervals on a bike. As you exercise, Heart Graph keeps track of where you are in the session and what’s coming up next, alerting you when it’s time to stop or move on. The trigger for the next set can be a simple time gap (“wait 30 seconds”) or based on heart rate to allow recovery before continuing (“wait until heart rate is below 120bpm”), giving a structured plan that adapts to how your body is responding each time. Premium Features include: * View and analyse the time spent in each of five configurable heart rate zones * Add annotations to the graph, during recording or at any time afterwards, to help identify key events * Heart rate alarms when your heart rate changes zone or goes above or below configurable thresholds * Spoken heart rate at regular intervals or on zone changes, so you needn't watch the screen * Directly compare graphs for equivalent sessions * Sync your sessions between your iPhone and iPad via iCloud Drive * Automatically import new workouts and a chosen time period every day from Apple Health, or bring in months of past data in one go * Compare statistics (such as max, mean and resting heart rate) across sessions * Record a session to explicitly measure resting heart rate while you relax * Audio rep counting - the app keeps count so you never lose track * Import Garmin TCX and GPX format files * Export data to TCX, Polar HRM or CSV files for further analysis, e.g. in Excel * Export one or more sessions as a PDF, complete with summary, heart rate graph and a table of your annotations, ready to share or print Heart Graph requires an external sensor to record heart rate, such as: * A Bluetooth (BTLE) sensor such as the Wahoo Trackr / Polar H10 chest straps, or Mio Alpha watch * An Apple Watch or AirPods Pro 3 * An ANT+ sensor connected using the Wahoo Key DISCLAIMER: Heart Graph is not a medical device, and you must always seek a doctor’s advice before making any medical decisions.

RHR Tracker is an advanced resting heart rate tracker for the Apple Watch. RHR Tracker integrates with the Health app and uses Resting Heart Rate measurements recorded by the Apple Watch. Your resting heart rate is the average heart beats per minute measured when you’ve been inactive or relaxed for several minutes. A lower heart rate typically indicates better heart health and cardiovascular fitness. Changes in your RHR can also be an indication of illness or stress etc. Key features: -Tracks changes in your RHR. -Notifies the user if RHR is clearly elevated. -Allows to log symptoms that could be causing the changes in RHR. -Add RHR complications to your watch faces. -Collects RHR measurements within the day. Normally your Apple Watch will only store the latest daily measurement. With RHR Tracker also other daily values will be stored and you can see your daily min max values in the Apple Watch app. -Morning report that will tell you how your RHR data collected during the night or first thing in the morning compares to your long-term average. -Information read by RHR Tracker is only used locally on your device while relevant data is synced to your personal iCloud. This data can not be accessed by anyone else but you. -After your free seven day trial ends, you can continue using RHR Tracker by purchasing Lifetime access as an in-app purchase. Please note that notifications can get delayed or in some cases even dismissed if the app isn’t granted runtime in the background. By adding RHR Tracker as a complication, you will give RHR Tracker a better chance in providing notifications in time. If you have any question, please contact us at contact@sydvesti.com
