## What is Base Cardio?

Base counts your weekly zone 2 minutes from Apple Health — across recorded workouts and qualifying everyday activity — so you can see where your week stands without adding up sessions yourself.

Keep using the workout app you love: if it saves your workouts and heart rate to Apple Health, Base counts them. Or start a dedicated zone 2 workout in Base on Apple Watch.

YOUR WEEK, ALREADY COUNTED
Connect Apple Health to follow your zone 2 minutes against a goal you choose. Outside a recorded workout, activity needs sufficiently frequent heart-rate readings and supporting Apple Exercise Time. Unsupported gaps do not count; Base does not credit every movement.

STAY IN YOUR ZONE
Start an optional workout in Base on Apple Watch for live guidance in your personalized zone. Follow your session on your wrist or its mirrored iPhone display.

SEE WHAT COUNTED
Explore the walks, runs, rides and qualifying everyday activity that contributed. Look back through your history and follow your consistency over time.

ONE GLANCE AWAY
Keep your weekly progress visible with iPhone widgets and Apple Watch complications.

YOUR HEART, OVER TIME
See resting heart rate and HRV trends alongside your zone 2 activity. Personal trends, not a diagnosis or a promised health outcome.

PRIVATE BY DESIGN
Your heart-rate readings, workout records and measured zone 2 totals are processed on your devices, not sent to our analytics services. Usage analytics and crash reporting are on by default and can be turned off anytime in the app; in the EU, the UK, Norway, Iceland, Liechtenstein or Switzerland, or where Base can't tell your region, they stay off until you agree. No Base account required.

Base needs compatible heart-rate data in Apple Health, with workout records or supporting Apple Exercise Time for qualifying activity. Live workouts require a compatible Apple Watch. Requires iOS 26 or later; the Watch app requires watchOS 26 or later.

A subscription is required. Eligible new subscribers can start a 14-day free trial. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in Settings, then your name, then Subscriptions. Any unused part of a free trial is forfeited when you subscribe. Current prices and terms are shown in the app.

### 5/5 — Essential for longevity-driven endurance tracking

*2026-11-08*

If you follow a structured longevity and aerobic conditioning protocol (like Peter Attia’s Outlive framework), tracking weekly Zone 2 volume usually means exporting or pulling manual reports just to verify you're hitting your targets. Base: Zone 2 Cardio Tracker completely automates that friction. The interface is clean, the data parsing is spot-on, and it integrates seamlessly with an Apple Watch ecosystem without cluttering your workflow. It’s an absolute game-changer for anyone taking their aerobic base and metabolic health seriously. Highly recommended!

### 5/5 — Great HR tracker!

*2026-11-07*

I’ve been looking for a way to keep track of all my zone 2 minutes. This is perfect!

**Developer response:** Thank you! Glad Base makes your zone 2 week easy to follow.

## Version history (last 5 releases)

### 1.0.6 — 2026-11-11

See each workout's distance, pace and route on your iPhone.

New:
• Open an outdoor walk, run, hike or ride in Base and scroll below the heart rate chart to see its distance and pace (a ride shows speed), with a map of the route.
• It works for workouts from other apps too, like Apple's Workout app.
• To show these, Base asks Apple Health once for workout routes and distances. If you'd rather not share routes, you'll see the numbers without a map.

Also: a few lines that ran past the edge on smaller screens now fit.

### 1.0.5 — 2026-11-10

See your distance and pace when you finish a workout on Apple Watch.

New:
• When you end an outdoor walk, run or hike you started in Base on Apple Watch, scroll down on the finish screen to see its distance and pace. An outdoor ride shows its speed instead.
• The numbers are the workout as Apple Health saved it. Under half a mile (or 0.5 km), you'll see the distance without a pace.

### 1.0.4 — 2026-11-09

Privacy updates for the EU and your iPhone backup, plus fixes.

New:
• In the EU and Liechtenstein, usage analytics and crash reports now stay off until you agree, as they already do in the UK, Norway, Iceland and Switzerland. If you never answered, Base asks you once on Week.
• Your saved workout figures, resting heart rate readings and Heart trends no longer go into your iPhone backup. On a restored iPhone, Base rebuilds them from Apple Health.
• In setup, the goal step starts at 60 minutes unless your Apple Health history points to 90 or 150, and the 150 choice is now called Research-backed.

Fixed:
• Week's day labels are brighter and easier to read, and they grow with your text size.
• As Week's minutes count up, TO GO and OF GOAL match them from the very first moment.
• From now on, after you restore your iPhone from a backup, the widget shows a dash until Base has this week's numbers, instead of old minutes from the backup.
• On a restored iPhone, History keeps saying your saved timeline is reconnecting while it retries, instead of switching messages back and forth.
• During a walk that runs past midnight on Sunday, the walk's minutes beside your week total now count only this week's part.
• On the sheet that asks for next week's goal, VoiceOver now says "Pick" for the suggested goal, matching its tag.

### 1.0.3 — 2026-11-07

Fixes for your weekly numbers, Apple Watch, VoiceOver and large text.

New:
• Keep tracking workouts with the app you love: if it saves them to Apple Health with your heart rate, Base counts them. And when you start a zone 2 workout in Base on Apple Watch, it now saves its distance, calories, steps, route outdoors and more to Apple Health too.
• Before your next workout in Base on Apple Watch, Apple Health asks you to allow these, and for an outdoor workout started on the Watch, the Watch asks for your location to save the route.
• Usage analytics and crash reports are now on by default, except in the UK, Norway, Iceland and Switzerland, or where Base can't tell your region. They never include your health data, and you can turn them off anytime in You → App & privacy.
• History waits for your real resting heart rate instead of showing numbers based on your age alone.
• iPhone Duo keeps your place when you fold or unfold it.

Fixed:
• On iPhone Duo, text no longer sits too close to the edge of the screen.
• Your weekly numbers now wait until they're right in more places, from past weeks to the first open of a new week.
• On Week, TO GO and % of goal now count along with your minutes.
• If Base is open at midnight on Sunday, Week moves to the new week without showing last week's minutes as this week's, and the month recap waits for the finished week.
• The Lock Screen and Dynamic Island follow your zone when Apple Watch updates it during a walk.
• Opening Base during a walk shows this week's minutes plus the walk, never the walk counted twice.
• After you change your goal or zone, Week and History show a short loading look, then this week's new numbers, never the old ones. The widget and Apple Watch wait too, and if the recount can't finish, Week and History offer Try Again.
• Past weeks may be recounted on your own heart zones, so their totals can change. While that happens, the widget, badges and Heart's all-time number wait for the new figures instead of showing old ones.
• If you allow Apple Health after setup, Base waits for your resting heart rate before it totals your week, so once Apple Health has seven days of resting heart readings from the last two weeks, your minutes use your own heart zones.
• Apple Watch updates when your iPhone sends new numbers, and only says a workout is saved once Apple Health has it.
• Apple Watch now recounts a walk when your zone changes and waits to show last week's result until it's up to date. If Base restarts mid-walk after a zone change, your Watch shows a dash and your Lock Screen leaves out time in zone, rather than a count that might be off.
• VoiceOver now reads what the screen actually shows on the workout screens, the Lock Screen, Heart, History, the plan screen and more.
• At the largest text sizes, the question about sharing usage data keeps its words whole and its buttons on screen.
• At the largest text sizes, you can now scroll to every plan and button on the plan screen.

### 1.0.2 — 2026-10-30

Base now fits both screens on iPhone Duo, folded or open.

On iPhone Duo:
• Folded, the tabs sit in a pill under the clock and step aside on pages you open, so Back always shows.
• Open, the tabs sit in a small block under the clock, Week's chart fills the room, Heart and You start below the tabs, and Earned shows badges still to win.
• Week's header and goal tag hold still in a Live Activity. Sheets, the paywall and the finish screen stay clear of the clock, and Heart and History run under it.
• Ember stays clear of Share, and "Keep going" is easier to read.
• Setup and weekly minutes no longer overlap text.

Also:
• Bigger text and VoiceOver work better across Week, History, the workout screen and setup, and VoiceOver reads each tab as one item.
• Smoother scrolling, and switching tabs on the iPhone Duo's outer screen is quicker.
• Fixed crashes from Heart to History to Week and at the end of a walk on Apple Watch; Watch no longer shows your week empty.
• Week's wave now shows each day's minutes exactly as the list does.
• At the largest text size, the goal sheet opens at its heading.
• Setup asks your age in one row when Apple Health has none.
• Subscription prices stay in view at larger text.
• Heart's days-added estimate no longer shifts with today's heart rate.
• Two-line badge names line up on Earned.
