Get started

Connect your sensor Set your training zone Start your run

Connect your sensorPut on your heart rate sensor (wet a chest strap’s electrodes first), then on the Run tab, tap Connect on the sensor card. Under Sensors nearby, tap Connect next to your sensor. You can also find this in Settings › Sensor.
Set your training zoneIn Settings, open your run band and tap Use to copy the zone aerozone calculates for you. Or set your own floor and ceiling.
Start your runChoose your run type and outdoor or indoor, start, and put your phone away.

Tip: try Test mode first to hear every sound, no sensor needed. Go to Settings › Test mode, pick a Trace and a Speed, then tap Start test run.

Connecting a heart-rate sensor

Chest straps. Most chest straps support the standard Bluetooth heart-rate profile used by aerozone. Wear the strap securely and moisten the electrodes before connecting.
Arm bands, watches and other bands. If your device supports Bluetooth heart-rate broadcasting, enable this feature before attempting to connect it to aerozone.

Your training zone in detail

Max heart rate. Choose From my age, or I know it if you have a number from a proper test. A measured maximum heart rate is generally a better starting point than an age-based estimate.
Resting heart rate. Optional, but it makes your zone more personal. aerozone can read it from Apple Health, or you can type it in.
Calculated zone. aerozone suggests 60 to 70% of your heart rate reserve. Tap Use to copy it.
Your own zone. Set your floor and ceiling with the + and − buttons.
Two run types. Easy run band and Long run band each have their own zone, and each run uses the band for the type you choose.

What the sounds mean

What’s happening	What you hear	What to do
In your zone	Quiet	Hold this effort
Nearing your ceiling	A rising chime, once	Ease off a touch
Too high and climbing	A fast double-beep every 2 seconds, and “Too high”	Reduce your effort until your heart rate begins to fall towards your target zone
Too high but coming down	A soft beep every 2 seconds, and “Coming down”	Hold this pace while your heart rate catches up
Too low	A low beep every 2 seconds, and “Too low”	Pick it up a little
Back in your zone	“Good”	Carry on

Spoken prompts repeat every 10 seconds, in a female or male British voice. Turn them off in Settings for tones only.

Calm by design. By default, “Too high” only starts once you’re 2 bpm or more over your ceiling for 5 seconds, so brief blips stay silent. You can change the timing in Settings, under Alerts.

Warm-up. While you warm up there are no low beeps, just a spoken update every minute. Coaching starts when you reach your zone, or after 10 minutes.

Test mode. Runs a pretend heart rate trace at 1x or 10x speed, so you can hear every sound quickly. Test runs are marked Test in History.

Fixes

I can’t hear anything.

aerozone stays quiet while you’re in your zone, and between updates during warm-up. Glance at the screen: if it says In band, all is well.
Turn up your iPhone’s volume during a run, and check your headphones are connected.
Check spoken prompts are on in Settings if you want to hear the voice.
The silent switch and Focus modes don’t mute aerozone. Only the volume buttons do.

aerozone can’t find my sensor.

Put the sensor on. Many chest straps sleep until they detect a heartbeat, and dry electrodes may not pick one up, so wet them.
Close other apps that might be connected to it. Many sensors only connect to one app at a time.
Check aerozone has Bluetooth access: on your iPhone, go to Settings, then Privacy & Security, then Bluetooth.
Watches and other bands: check heart rate broadcast is on.
Still stuck? Restart the sensor, or swap its battery.

The coaching stopped after a call.

aerozone pauses for phone calls and Siri, then says “Alerts on” when it starts coaching again. If alerts can’t play, the run screen shows “No sound: alerts can’t play” and aerozone keeps retrying every few seconds. Opening aerozone also makes it retry. Check your volume isn’t turned down.

My heart rate jumps around.

Chest strap: wet the electrodes and tighten the strap. Static from synthetic tops in dry air can cause odd spikes.
Arm band or watch: wear it snugly. Optical sensors are least steady during sprints and intervals.

There’s too much beeping.

In Settings, under Alerts, you can adjust how long you must be outside your target zone before alerts begin, how early the warning chime sounds, and how frequently alerts repeat. If needed, review your training zone settings to make sure they reflect your intended training intensity.

I don’t see pace or distance.

Outdoors, aerozone needs Location access while you’re using the app. Indoor mode doesn’t use GPS.

There’s no pace drift in my summary.

aerozone only shows pace drift when it’s reliable. On hilly routes it can’t compare the two halves fairly, so try a flat loop.

My resting heart rate isn’t filled in.

Allow aerozone to read resting heart rate in Apple Health, or type it in yourself.

FAQ

Why does it say “Coming down” when I’m still too high?

Your heart rate takes a moment to follow your effort. If you’ve already slowed enough, aerozone tells you to hold your pace rather than slow down more.

Do I need Apple Health?

No. You can type in your resting heart rate, or leave it out.

Does it work with an Apple Watch?

Not at the moment. aerozone connects to Bluetooth heart rate sensors.

Where are my runs stored?

On your iPhone only. To delete a single run, swipe left on it in History and tap Delete. Deleting the app deletes all your runs.

How do I restore a purchase on a new phone?
