About

Your training. Your rhythm. Everything in one place. HFF brings flexible planning, workout logging and useful analysis together. Build strength and HFF sessions, create Metcons, and keep HIIT, runs, rides, soccer, swimming and other activities in view. You decide what fits today. TRAIN YOUR WAY • Build workouts from exercises, sets, reps, weights and cardio. • See what you achieved last time while logging each set. • Create Metcons as AMRAP, EMOM or For Time — including after strength work. • Combine supersets, warm-up, strength, Metcon and cool-down. • Record open sessions or add individual personal bests. PLANS FOR REAL LIFE Create multi-week plans from open workouts, Metcons, recording days and other activities. Organize long plans into sections, move to the right week after a break and keep private block notes. Export plans, share eligible plans or create a PDF. THE HFF METHOD — ONE PART OF THE APP Main, Push and Pull form a compact foundation for regular training. Adapt volume and effort to your day. The HFF Method is one way to use the app, not a rule for every workout. PUT PROGRESS IN CONTEXT • Exercise history, personal bests and heaviest sets • Guidance from your best lift — a real single, or an estimated 1RM • A weekly overview including imported activities • Weekly reports, badges and progress photos • Effort across the last seven days • Daily readiness from your overnight recovery data • A Fitness Score built from available training and health data With limited data, HFF provides cautious guidance that is clearly marked as provisional. Missing data is not treated as poor performance. The more relevant data you choose to share, the more meaningful your Fitness Score and readiness can become. APPLE WATCH REMOTE CONTROL Control the workout prepared on your iPhone from your wrist: start, pause, check sets, skip exercises, adjust rest and log Metcon rounds. When a chest strap is connected to your iPhone, its heart rate also appears on Apple Watch. OPTIONALLY CONNECTED Connect Apple Health to import activities, export completed sessions and add context from the health data you allow. Use any standard Bluetooth chest strap or sync training data through your private iCloud. In private Community groups, join challenges, send preset encouragement and share training plans. There are no public profiles, feed or free-text chat. No HFF account. No ads. No tracking. FREE TO START Free includes a curated exercise selection, flexible workouts and plans, history, weekly overview, progress photos, Community and up to three custom exercises. HFF PRO HFF Pro unlocks additional content and analysis: • full exercise library and custom exercises without the free limit • AI Coach for questions, catalog search and workout suggestions • Fitness Score history, breakdown and detailed charts • photo, body-measurement, readiness and muscle-group comparisons • private one-to-one coaching with shared plans and progress values Depending on your device, the AI Coach uses Apple Intelligence on your iPhone or a provider you connect. Before anything goes to that provider, HFF shows the destination and data categories and asks for consent. HFF is not a medical device. Fitness Score, readiness and effort provide general guidance and do not replace diagnosis or medical advice. HFF Pro is available as an auto-renewable monthly or yearly subscription through Apple. The price and any trial are shown before purchase. Your subscription renews until cancelled. Manage or cancel it in your Apple Account settings and restore purchases in the app. Privacy Policy: https://hff.weblaunch.at/privacy.html Support: https://hff.weblaunch.at/support.html Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

What's New in HFF

1.5

October 26, 2026

New in 1.5 • Plans: a training you do several times a week now has its own days — Day 1, Day 2 and so on. Add exercises to a single day, or to every day of this training. • Start any day in any order. Each day with exercises has a big Start button, and the Today card lets you choose when more than one is ready. • A day with exercises counts when you start it from the plan. Free trainings and Apple Health activities fill the open days. • Did more than planned? It shows as “1 more than planned” instead of disappearing. • The plan recap at the end now counts everything that fulfilled your plan — workouts, cardio from Apple Health and checked-off days — per training. • Plan progress now includes activities from earlier weeks. • Change the start date of a running plan. • Workout builder: hold and drag to reorder exercises in HFF and Metcon blocks. • Exercises: “Measured by” can be changed even after you have trained with an exercise. Your own exercises can list the muscles that also work. • Metcon lines show reps or minutes exactly as the exercise is measured. • The plan card uses the same check mark everywhere: tap to check off, tap again to undo. • Apple Watch: the check mark on the last cool-down step ends the workout, and the first step reaches the watch more reliably. • Fixes: designing a training in a plan keeps your order and exercises, and a running plan no longer gets replaced by an older one.
