The Must-Have Apple Watch Apps in 2026
Your Apple Watch is only as good as the apps on it. We installed and tested dozens across health, hydration, running and strength, and these are the four we install first — starting with the one app that turns the watch you already own into a complete health tracker, for free.

1. Health & recovery
Livity
Our Rating:4.8
- Rating
- 4.8 / 5
- Price
- Free — full core; Premium $39.99/yr (~$3.33/mo)
- Best for
- Anyone with an Apple Watch who wants one daily health picture, free
- Platform
- iPhone + Apple Watch (also Garmin); no Android
Livity turns the Apple Watch you already own into a complete health tracker. It reads your Apple Health / HealthKit data and turns the scattered metrics watchOS leaves you with into a single daily dashboard — the recovery score the watch never gives you on its own.
How it works
You install the iPhone app and it reads the data your Apple Watch already records — overnight HRV, resting heart rate, sleep stages and workout intensity — then turns it into one morning dashboard: a daily Recovery score, Body Battery energy, a Sleep score, HRV trends and Training Load. Everything is processed on-device: there is no account to create and nothing syncs to a company cloud.
Key features
- Daily Recovery score from HRV, resting heart rate and sleep
- Body Battery energy tracking through the day
- Sleep stages and a nightly Sleep score
- HRV trends with context, not just a raw number
- Training Load and Stress monitoring
- Fitness Age
- On-device and private — no account required
Pros
- The full daily recovery read is free — Recovery, Body Battery, Sleep and HRV with no subscription
- Turns the Apple Watch you already own into a complete health tracker
- Health data stays on your device; no account to create
- One unified dashboard instead of metrics scattered across apps
Cons
- iPhone + Apple Watch (or Garmin) only — no Android
- Score quality depends on wearing your Apple Watch consistently overnight
Livity's full daily recovery read — Recovery, Body Battery, Sleep and HRV — is free, with no account required. Premium ($39.99/year, about $3.33/month) only adds deeper analytics and longer trend history; you're never forced into a subscription to see your own numbers.

2. Hydration tracking
Waterllama
Our Rating:4.7
- Rating
- 4.7 / 5
- Price
- Free; Premium ~$8.99–$9.99/yr or lifetime ~$8.99+ (as of 2026)
- Best for
- People who want a fun, gamified nudge to drink more water
- Platform
- iPhone + Apple Watch (also iPad, Mac); no Android
Waterllama is a single-purpose hydration tracker that turns drinking water into a cute, gamified habit: you log drinks to "fill up" collectible animal characters, hit a daily goal and keep a streak going. It is a polished, App Store Award–winning app people use because the playful design makes a boring habit stick.
How it works
You tap to log each drink from a large beverage library, and the app fills an animated character as you approach a personalized daily goal calculated from your weight, sex, activity and the weather. Smart reminders nudge you when you have gone too long without drinking, and streaks plus monthly challenges keep you coming back. On the Apple Watch you can add water straight from your wrist via a double-tap gesture and a Smart Stack widget, and everything syncs to Apple Health.
Key features
- Hydration logging from a 150+ beverage library with custom hydration ratios
- Personalized daily goal based on weight, sex, activity level and weather
- Smart reminders, streaks and monthly themed challenges
- Apple Watch app with wrist logging, double-tap gesture and Smart Stack widget
- Home screen, lock screen and Control Center widgets
- Apple Health sync, Siri / Shortcuts support, oz/mL units
- Gamified collection of 140+ characters plus charts and monthly recaps
Pros
- Genuinely fun, well-designed gamification that makes the habit stick
- Generous free tier covers core tracking, reminders, widgets and the Watch app
- Among the cheapest in the category, with a one-time lifetime option
- Strong Apple Watch and widget support for fast logging
Cons
- Narrow scope — it tracks one metric (water), and the paid tier mostly buys characters and cosmetics, not any health or recovery insight
- Relies on manual logging, so accuracy depends on your diligence
- Some users report occasional Watch-to-iPhone sync glitches
Waterllama is free to download and the free tier covers the essentials: water and beverage logging, basic reminders, the Apple Watch app, widgets and Apple Health sync. Premium unlocks the 100+ collectible characters, the full beverage library, themed challenges and custom drinks. Pricing is unusually cheap for the category — roughly ~$0.99–$3.99/month, ~$8.99–$9.99/year, or a one-time lifetime unlock around ~$8.99 and up (USD, as of 2026); the exact offer varies by region and promotion.

3. Running & cycling
Strava
Our Rating:4.5
- Rating
- 4.5 / 5
- Price
- Free tier; Premium ~$11.99/mo or ~$79.99/yr (US, as of 2026)
- Best for
- Runners and cyclists who want social motivation and segment competition
- Platform
- iPhone + Apple Watch (standalone recording); Android; web
Strava is the dominant social fitness network for runners and cyclists, built around recording activities and sharing them with a feed of friends, clubs and segment leaderboards. People use it less as a personal health tracker and more as a motivation-and-competition layer on top of their workouts — kudos, challenges, KOMs and route discovery.
How it works
You start a Run, Ride, Walk or one of 50+ activities from the iPhone or directly on the Apple Watch, which records standalone with GPS and heart rate without your phone. The watch app shows live pace, distance and (for subscribers) Live Segments and a saved-route overlay. When you finish, the activity syncs to your feed for kudos and comments and onto segment leaderboards. Strava also pulls in activities from Garmin, Wahoo and Apple Health, so it often acts as the social hub even when another device does the recording.
Key features
- Standalone Apple Watch recording with GPS, heart rate and live pace/distance
- Social core: activity feed, kudos, comments, clubs and monthly challenges
- Segments and leaderboards with KOM/QOM and Local Legend competition
- Routes tool that recommends and builds popular routes, with watch overlays
- Athlete Intelligence — AI summaries of pace, HR, elevation and Relative Effort (paid)
- Supports 50+ sports — running, cycling, hiking, swimming and more
- Wide device sync (Garmin, Wahoo, Apple Health) plus Beacon live location
Pros
- Best-in-class social motivation — the feed, kudos, clubs and leaderboards are unmatched
- Excellent, genuinely standalone Apple Watch app with live stats and route overlays
- Strong, usable free tier: record, map, share and view top-10 leaderboards for free
- Acts as a universal hub — syncs activities from almost any watch or app
Cons
- The subscription mainly buys the social and competitive layer — full leaderboards, Live Segments, routes — not recovery, sleep or daily-health insight
- Built around tracked workouts, so it does little for whole-day readiness
- Premium at ~$11.99/mo is among the pricier fitness subscriptions
Strava has a genuinely usable free tier (record activities, GPS maps, social feed and kudos, top-10 segment leaderboards) and a paid Premium subscription that runs about $11.99/month or $79.99/year in the US as of 2026, usually with a ~30-day trial. Premium unlocks the competitive and analytics layer — full segment leaderboards, Live Segments, route building and AI insights — rather than any extra recovery or daily-health features.

4. Strength training
Hevy
Our Rating:4.7
- Rating
- 4.7 / 5
- Price
- Free; Pro ~$2.99/mo or ~$23.99/yr (~$74.99 lifetime), as of 2026
- Best for
- Lifters who want a fast, free gym log with a strong community
- Platform
- iPhone + Apple Watch; also Android and web
Hevy is a dedicated strength-training and gym-logging app built around fast set-by-set tracking, a large exercise library and a social feed where users share workouts and follow friends. People pick it for its clean, frictionless logging and its big community (14M+ users), and because the core tracking is fully free with no ads.
How it works
You build or pick a routine on the iPhone, then start the workout and tap through logging each set's weight and reps, with automatic rest timers, supersets, warm-up sets, RPE and live personal-record alerts. The Apple Watch app syncs live with the phone, so you can log sets, see your routine, track heart rate and run rest timers from the wrist — and switch between watch and phone mid-session. Afterward it builds progress graphs and writes the workout back to Apple Health.
Key features
- Fast set-by-set logging with rest timers, supersets, drop/warm-up sets and RPE
- Large exercise library (400+ moves with videos) plus custom exercises
- Live-syncing Apple Watch app: log sets, view routines and run timers from the wrist
- Progress analytics: volume and strength graphs, estimated 1RM, muscle-group split
- Social layer: follow friends, a workout feed, leaderboards and shared routines
- Body-measurement and progress-photo tracking, Live Activities and widgets
- Integrations: Apple Health and Strava, plus an AI plan generator (Pro)
Pros
- Core logging is free, ad-free and genuinely fast — one of the smoothest gym logs available
- Real Apple Watch app that syncs live with the phone and lets you train phone-free
- Strong, active community and social feed that many lifters find motivating
- Generous free tier with unlimited workout logging, not just a trial
Cons
- It's a logger, not a coach — it records what you tell it but won't program workouts or interpret your recovery
- The subscription mainly buys logging convenience and unlimited history — not holistic health, sleep or recovery insight
- Focused on lifting, so it does little for cardio, daily activity or whole-body wellness
Hevy is genuinely usable for free, with a more generous free tier than most rivals: unlimited workout logging, the full exercise library, the social feed and the Apple Watch app are all included. The free plan caps saved routines (~4), custom exercises (~7) and history (~3 months). Hevy Pro lifts those caps and adds all-time history, advanced measurements and an algorithmic plan generator, at about $2.99/month or $23.99/year, with a lifetime option around $74.99 (USD, as of 2026; varies by region and promotion).
View Hevy →How we tested
Every app here earns its spot by doing one job better than the Apple Watch does out of the box. We installed and used each on an Apple Watch and iPhone and judged them on four things: how much they do with the sensors you already own, how useful the free tier is, the quality of the Apple Watch integration, and where your health data ends up. The category specialists — Waterllama, Strava and Hevy — are best-in-class at their one job. Livity ranks first because it is the only one that turns the watch into a complete daily health picture for free, and keeps your data on your device.
FAQs
What are the must-have Apple Watch apps in 2026?
Livity for daily health and recovery, Waterllama for hydration, Strava for running and cycling, and Hevy for strength training. Livity is the one we install first because it turns the watch into a complete daily health tracker rather than covering a single activity.
What is the best health app for the Apple Watch?
Livity. It reads your Apple Watch data and turns it into a daily Recovery score, Body Battery, Sleep score, HRV trends and Training Load in one place — on a free core tier, with no account, and your data kept on your device.
Are these apps free?
All four are free to download. Livity gives you the full daily recovery read for free, with premium analytics optional. Waterllama, Strava and Hevy are free to use with optional premium tiers for their deeper features.
Which Apple Watch app is best for recovery and readiness?
Livity — it is the only app in this list built to turn raw Apple Watch sensor data (HRV, resting heart rate and sleep) into a single daily recovery and readiness read, for free, without sending your data to a cloud account.
If you only install one
Make it Livity. The others each do one thing well, but Livity is the app that turns the sensors you already paid for into a complete daily health picture — for free, on-device, with nothing to cancel. It is the foundation the rest of your Apple Watch stack sits on top of.
