PulseAnvil requires iOS 18.6 or later on iPhone and watchOS 11.6 or later on Apple Watch. It is compatible with Apple Watch Series 6 and newer, the Apple Watch SE (2nd generation and later), and all Apple Watch Ultra models.

PulseAnvil reads live heart rate data directly from your Apple Watch throughout every session. Premium subscribers see real-time color-coded zone feedback — Rest, Fat Burn, Cardio, Threshold, and Peak — on both iPhone and Apple Watch as they train. Free users get a 90-day heart rate heat map after each workout, giving a clear picture of training consistency and effort trends over time.

Recovery Readiness is a 0–100 daily score that tells you how prepared your body is for training today — before you even start. Every morning, PulseAnvil pulls three overnight signals from HealthKit: your Heart Rate Variability (HRV) compared to your personal 30-day baseline, whether your resting heart rate is elevated above your recent 7-day average, and how your previous night's sleep duration and quality measure up. These three signals are weighted and blended into a single score. A score of 70–100 means your body is primed to push hard. 40–70 suggests moderate effort or reduced volume. Below 40, prioritise recovery or a light Zone 1–2 session. The score refreshes automatically each morning and everything is calculated on-device — nothing leaves your iPhone.

HRV stands for Heart Rate Variability — the tiny fluctuation in timing between consecutive heartbeats. A higher HRV generally means your nervous system has recovered well and your body is ready to handle stress. A lower HRV can signal fatigue, poor sleep, or that your body is still adapting from a hard session. Elite athletes have used HRV for years to guide training decisions, but it is just as useful for recreational athletes. Instead of guessing whether to go hard or take it easy, HRV gives you an objective signal. PulseAnvil uses your overnight HRV from HealthKit — collected passively while you sleep — so there is nothing extra to do. It simply shows up in your Recovery Readiness score each morning.

Yes. The custom workout builder lets you create routines from scratch: add any exercise, set timed intervals, configure rest periods, and group sessions by category. Every workout you create is also indexed in iPhone Spotlight, so you can find and launch it from your home screen in seconds.

Absolutely. All your workouts and training data are stored locally on your devices so you can train in the gym, on a trail, or anywhere without a signal. iCloud sync (a Premium feature) automatically backs up and syncs your data end-to-end encrypted whenever a connection is available.

Workouts and settings sync in real time over Bluetooth when your iPhone and Apple Watch are paired. Premium subscribers also get iCloud sync, which keeps all your data consistent across every Apple device you own — your full history travels with you.

Yes. PulseAnvil connects to Apple HealthKit to read and write workout data, heart rate, and activity metrics. Your fitness data stays in Apple's secure ecosystem — PulseAnvil never sells or shares it, and you can revoke access at any time from your iPhone privacy settings.

PulseAnvil is free to download and genuinely useful without ever paying. The free tier includes the full workout builder, both Timed and Set & Weight tracking modes, per-set volume calculation (Weight × Reps per set with session totals in your journal), workout history, progress selfies, a 90-day activity heatmap, 12-week trend graphs, Consistency Score, Weekly Duration, and Most Trained Category. That's a complete training toolkit at no cost. Premium unlocks the Apple Watch companion app, iCloud sync, live heart rate streaming, color-coded HR zone feedback, and four advanced metrics: Recovery Readiness (HRV-based daily readiness score), Progress Pulse (composite session quality score), Dominant Zone Analysis, and Weekly Avg Intensity trend graph. Premium is available as a monthly or annual plan, managed entirely through the App Store.

Just long-press any workout in your list and drag it to a new position. You can put tomorrow's session at the very top for instant access, or organize by muscle group, intensity, or any order you prefer. Changes sync to your Apple Watch automatically.

Privacy is built into the core of PulseAnvil. Sign in with Apple means no password to manage and no email shared. HealthKit data never leaves Apple's ecosystem. All iCloud sync is end-to-end encrypted. There is zero third-party tracking or advertising.

PulseAnvil is in final pre-launch and will be available on the App Store very soon. Follow @NorthTactics on X for the launch announcement — that's where early access details will go first.
