01

Goals, experience, the days you can train, your equipment, and any injuries or health considerations.

02

Get your week

A 7-day training plan and macro-balanced meals, built together so they fit each other.

03

Train & cook, guided

Workout Mode walks you through every set. Cooking Mode walks you through every step.

04

Check in & adapt

A quick check-in after each workout, a weekly review and the Oracle keep the plan in step with how your week really went.

The library

Thousands of ways to train and eat.

Your plan draws on a large, structured library, so the week you get fits your equipment, your diet and your taste, and swapping something out is always one tap away.

  • Filter by muscle, equipment and level, or search by name
  • Recipes with photos, calories and macros, sorted to fit your targets
  • HD video guides for many exercises and every yoga pose

Coaching · What sets Fyvorin apart

Coaching that adapts with you.

Fyvorin looks at your training, the food you log and available progress signals to help you understand when an adjustment may make sense. Every suggestion comes with an explanation, and you stay in control.

01

Notice what matters

Identify relevant patterns across your training and available progress signals.

The review screen showing planned vs proposed sessions and the rule behind it
02

Understand the suggestion

See why an adjustment is recommended and what evidence supports it.

03

Stay in control

Review suggestions before applying them, then keep tracking your progress.

Food, too.

From what you log, your coach can spot a pattern, like protein under your target, and offer options for one planned meal; you pick. A meal you keep choosing can go on your plan's other days in one step, with Undo. Your weekly review puts training and food side by side, without claiming one caused the other.

A nutrition suggestion on Home: protein averaged 80 g a day against a 215 g target, with options for the breakfast burrito
Make it stick: a chicken and black-eyed pea curry instead of a pesto penne on two plan days, each listed before anything changes
The weekly review: six of seven days logged, calories and protein against target, and training and logged food side by side

Logged food may not be everything you eat. Nutrition suggestions are general guidance, not medical or dietary advice.

Your progress continues through check-ins and weekly reviews, helping you understand what is changing over time.

Wear OS

Your guided workout, on your wrist.

The Wear OS companion mirrors your guided workout from your phone, so you can follow a set, feel the tempo and log it without picking up your phone, with your day's water, meals and shopping list one tap away.

Every set at a glance

The exercise, set, load and rep count, side by side for one-sided work, with a ring that fills as you go.

Tempo you can feel

A distinct wrist vibration for each phase of the rep (lower, hold, drive) in step with the phone's guide.

Control it from the watch

Pause, resume, log the set, or pause and skip the rest; the phone follows.

Heart rate during the session

Your watch's heart rate streams to the phone while a guided session runs, and only then.

Water and meals from your wrist

Add a glass or a bottle of water, and log today's planned meals with one tap.

Your summary when you finish

Duration, sets, reps, volume and heart rate on the watch the moment the workout ends.

Needs a Wear OS 3+ watch paired with a phone running Fyvorin. Heart rate is optional and asks for your permission first. Workout values in these screens are sample data.

Your day

Your whole day, one timeline.

Home lays out today in order: meals by time of day, your workout as the thing to do now, and what's coming tomorrow. Tap anything to open it in place.

  • A clear “Now” that moves through your day as you log meals and train
  • Tap a meal for its photo and macros, or a workout for its breakdown
  • Steps, water and sleep rings that open 7- and 30-day history
Home with breakfast opened in the timeline: its photo, 501 kcal, 48 g protein, 3 g carbs and 32 g fat

Shopping list

Your meal plan, turned into a shopping list.

One list for the week or the next 3 days, built from your meals, sorted by store aisle, with amounts you can actually measure.

  • A picture for every item and one line per food, grouped by aisle
  • Weights next to cups and spoons, and how many to pick up for produce (“≈ 6 limes”)
  • Tick, remove or add your own, or mark “I already have this” for two weeks
  • Rebuilding keeps what you ticked, and the list notices when your meals change
  • Share it with whoever does the shopping

The Forge Oracle

Change the plan by just saying so.

Tell the Oracle what changed. It swaps exercises, reshapes a session to the time you have, logs what you ate and moves meals around, inside the rules of your plan.

I only have dumbbells today, and my right knee hurts. 30 mins max.
OracleUnderstood. I've swapped barbell squats for a knee-friendly dumbbell option and shortened rest to fit 30 minutes.
Replace my Tuesday dinner with salmon and asparagus.
OracleDone. Tuesday dinner is now salmon with asparagus (~650 kcal · 45 g protein).
Your results

Watch the work add up.

Every workout, step, night of sleep and weigh-in lands in one place, so the trend is easy to read and easy to stick with.

Steps over 30 days: a 9,581 daily average, a best day of 13,150 and a 7-day goal streak
Sleep over 7 days: 7 h 40 min last night against an 8-hour goal, 7 h 12 min on average
Body weight from weekly check-ins, easing from 77.8 to 75.0 kg over six weeks

Share stories, your way

Share a badge or a workout as a story: badge, minimal or detailed layouts, a clear background to place over your own photo, the colors you like, always signed Fyvorin.

Built around you

The plan bends to your life, not the other way round.

Your goals

Strength, muscle, fat loss, endurance or maintenance, with a daily calorie and protein estimate to match.

Your equipment

Full gym, home dumbbells or bodyweight only, saved per place you train.

Your body

Injuries and health considerations shape every plan, with cycle-aware adjustments if you choose them.

Training places

Home, gym or hotel: the plan follows your equipment.

Save each place you train with the equipment it has. Switch the active place in a tap and your workouts are built from what's there, so a hotel gym or a dumbbells-only day still gets a real session.

  • Home setups and commercial gyms, each with its own equipment
  • Find your gym by name or nearby, or start from a typical gym
  • Workouts and swaps use only what the active place has
Switch active environment: Home Gym is active, with a commercial gym saved as the other place

Every day, in one place

Water

Log a glass or a bottle in one tap, get a goal based on your weight, and optional reminders when you fall behind.

Sleep

Your phone can notice when you sleep, and you confirm it each morning. Sleep from a watch or sleep app comes in through Health Connect.

Steps

Steps from your phone or Health Connect, next to the rest of your day, with daily and monthly history.

Health Connect on Android

Fyvorin reads steps and sleep from Health Connect on Android, so your watch or sleep app can fill in your day. You choose what it can read, and you can turn it off in Health Connect at any time.

Plans are built on structured exercise and nutrition data, including ExerciseDB and Spoonacular. AI personalizes and adapts them; it isn't the only source of the facts.
