No single Apple Watch app covers every POTS need.

TachyMon sends haptic alerts when heart rate crosses limits you set. POTS Buddy adds a guided standing test, wrist symptom logs, and PDF or CSV exports. Bearable logs symptoms and triggers. Apple Watch saves health readings in Apple Health. Body Insights reads that history. It includes sleep, HRV, resting heart rate, and recovery trends.

Pick the app that matches the job. A live alert and a weekly symptom record are different tools.

1. Body Insights

Best for: sleep, recovery, and baseline changes recorded in Apple Health.

Body Insights is a recovery app that reads Apple Watch data through Apple Health. It shows sleep, resting heart rate, and HRV beside your usual ranges. Workouts, heart trends, and recent strain appear with them.

It does not sound an alarm when your heart rate rises. TachyMon and POTS Buddy do that on the watch. Body Insights shows what changed across the night, the workout, and the days before a flare.

Use it for pacing over several days, not for an urgent wrist alert.

2. TachyMon

Best for: real-time heart-rate alerts.

TachyMon shows your current heart rate and a recent moving average. It also shows the difference between them. You set upper and lower limits. The watch sends a haptic alert when a reading crosses one of those limits.

The iPhone app stores each alert's start time, duration, and highest or lowest heart rate. Paid features add charts, notes, PDF reports, and CSV exports.

3. POTS Buddy

Best for: a POTS-specific wrist companion.

POTS Buddy shows live heart rate, the change from the earlier reading, and the trend direction. Its guided standing test records heart rate after 1, 3, 5, and 10 minutes upright.

You can set two alert levels, log symptoms from the watch, and export charts, PDFs, or CSV files.

4. Bearable

Best for: symptom, trigger, medication, and flare journaling.

Bearable is a symptom journal, not a live Apple Watch alarm. You can record sleep, exertion, illness, and medication timing. You can also add hydration, heat, cycle phase, and stress.

Use it when you need a written record of triggers and flares.

5. Guava

Best for: health records plus symptoms.

Guava keeps records, symptoms, labs, appointments, and health history in one place.

Use it when you need a dated medical timeline for an appointment.

6. Apple Health

Best for: checking the data already on your phone.

Apple Health stores heart rate, resting heart rate, HRV, workouts, and sleep. It also stores Cardio Fitness and Cardio Recovery. Medication data and other records can appear there too.

Check it before adding an app. You may already have the reading you need.

Use one app for alerts and one for records

TachyMon or POTS Buddy can warn about a rise now. Bearable, Guava, or Body Insights can keep a dated record. The record can include sleep, symptoms, activity, and recovery.

Export the alerts before an appointment. Bring the symptom timeline from the same dates. The clinician then has times, readings, and symptoms from the same events.

What to check before choosing

Count the taps needed to log a symptom on the watch. Check whether you can silence an alert. Check whether you can change its threshold. Look for PDF or CSV exports if you share data with a clinician.

Seek medical care for fainting or chest pain. Do the same for severe shortness of breath or new neurological symptoms. A watch alert cannot find the cause or make the situation safe.

Sources and limitations

Apple Watch apps cannot diagnose or treat POTS. Use clinical care for diagnosis, treatment, and medication decisions. Seek help for fainting risk or symptoms that are new or severe.
