[SCREENS]

Every screen in the app, and the arithmetic behind it.

22 pages.

Health

• Health Connections: What Base Reads and Why One platform store, every wearable writing into it, and one honest limitation the operating system imposes.
• The Activity Screen: Where Your Energy Actually Went Everything that moved today, and an explicit refusal to count a lifting session as an energy event.
• The Heart Screen: Four Signals, and What Each Is For The most useful thing on this screen is a five-beat rise that shows up a day before you feel ill.

Energy

• Maintenance: The Number Everything Hangs Off One screen, read top to bottom as an argument: what you burn, what you set, what you actually averaged, and where it can physically have gone.

Body

• Measurements: What the Scale Cannot Tell You One tape measure disambiguates the single most important question a scale cannot answer.
• Progress Photos: The Only Record That Survives Your Memory Deleting the app erases everything it stores. A photo series is the one record you cannot reconstruct, so it lives somewhere else.
• The Weight Screen: Trend, Not Scale Raw scale weight swings four pounds on identical body composition. The trend is what you steer by.

Nutrition

• Micronutrients: Eighteen Nutrients, and Your Coverage A micronutrient total computed over 40% of your food is not a micronutrient total, so the denominator is on the screen.

Getting started

• Onboarding: Five Minutes, and Every Answer Is Editable Six questions asked before you have any reason to trust the app, so each one says why it needs the answer.

Daily loop

• The Dashboard: Energy, Training and Recovery The home screen answers one question — what does today ask of me — and every number on it is derived from your own data.
• The Food Log: Template Replay Instead of Database Search Most food trackers are built for discovery. A serious athlete eats the same thing most days, so this one is built for repetition.
• The Workout Screen: Confirm or Bump, One Tap Per Set The most-used screen in the app, designed so that a normal set costs one tap and nothing else.

Endurance

• The Endurance Screen: Prescribe the Session, Then Grade It One number per discipline decides everything, so it carries its own provenance — and every session gets graded against what it was actually prescribed.
• Thresholds: One Number Per Discipline, With Provenance Every band in the app is a percentage of this number, so it gets shown with the effort it came from and how much weight it will bear.

Training

• The Exercise Logger: Everything About One Movement One movement, its whole history, and the arithmetic that decides what it asks for today.
• The Program Editor: Splits, Rep Ranges and RIR Targets The split matters less than whether its volume fits what your endurance week leaves you.
• The Workout Summary: What the Session Actually Produced The three minutes after a session are the only time anyone reads a summary, so it is built for those three minutes.

Analysis

• The Insights Screen: Four Trends, Kept Separate Four numbers you can act on, instead of one you cannot.

Recovery

• The Recovery Screen: A Decision, Not a Number Most apps show you a recovery number and leave you to interpret it. This one converts it into a rep and a verdict.
• The Sleep Screen: Duration, Efficiency and Consistency Three inputs, weighted, with no percentile — because nobody else computes this number and there is no population to rank you against.

Weekly loop

• The Strategy Screen: The Weekly Brain One screen that holds the four decisions everything else executes.
• The Weekly Check-In: A Generated Packet, Not a Form The review that decides the next week, assembled for you rather than filled in by you.
