No. 001 / Strength, nutrition and habits

ReInvent

Understand it. Build it. Reinvent yourself.

A strength, nutrition and habit app that won’t hand you a template. The reasoning is included; the program isn’t. Local-first with optional cloud sync, no ads, no data sales.

01 / Features

What it does.

  1. 01 · Train

    A strength log that shows you what the work actually did.

    Screen: ReInvent’s workout screen mid-session: goblet squat sets logged at 24 kg for 8 reps, a running rest timer, and totals for sets, volume and exercises.

    exercises, with faceted search and custom entries
    ~870
    rank tiers per exercise, normalised for bodyweight
    8

    Ranks come from your own estimated one-rep max. No percentiles, no leaderboards. Stop training a lift and it keeps its peak; it’s never marked down.

  2. 02 · Fuel

    Intake tracking with the reasoning attached to every target.

    Screen: ReInvent’s energy and macros screen with the protein target open, showing how the grams-per-kilogram target is worked out and the research it cites.

    micronutrients, each with its derivation and a citation
    ~30
    menu items across 96 restaurant chains
    21,209

    Barcode and label scanning run on the phone, so they’re unlimited on every tier. Exercise calories never enter the budget, and no food gets a verdict.

  3. 03 · Build

    Habits you design, at a cadence you pick.

    Screen: ReInvent’s Build tab: a momentum score, the week’s check-ins, and a morning routine made of stacked habits.

    cadences, from daily to every N days

    fixed challenges or 21-day plans
    0

    Stacks chain a new habit onto one you already keep. A missed day is recorded and left alone.

Screens are captures of the iPhone app in a simulator, using a demo account with sample data.

02 / Commitments

Operating rules.

Published on ReInvent’s pricing and privacy pages.

  1. 01

    No investors, no advertising.

    The subscription price pays for the work. At least a quarter of subscription revenue is committed to product development each year.

  2. 02

    Data isn’t for sale.

    No ads or advertising SDKs. Nothing is sold or shared for cross-context advertising, and user data is never used to train a model.

  3. 03

    What runs on the phone isn’t metered.

    Logging, charts, habits and scanning run on the device and cost nothing per person, so no tier limits them. Only work on servers paid for by the request can carry a limit.

  4. 04

    Paid adds; it doesn’t carve out.

    Nothing that works today moves behind a payment later. If a subscription lapses, what you’ve built keeps working and only the editor locks.

  5. 05

    Revenue sets the release order.

    iPhone first, because it costs nothing extra to ship. Android follows once revenue covers its maps service. Features with running costs come after that.

03 / Roadmap

Release order.

No dates, and nothing claimed before it exists. Each phase is paid for by the one before it.

  1. Phase 01 · Next

    iPhone

    App Store

    Train, Fuel and Build, with the Free, Pro and Founders plans. It costs nothing extra to ship.

  2. Phase 02 · After iPhone

    Android

    Google Play

    Once revenue covers the Google Maps service Android needs. The build already runs on Play’s internal track.

  3. Phase 03 · Planned, not built

    Funded features

    Paid for by revenue

    Things with a running cost, roughly in this order:

    • Improved workouts
    • A larger, licensed food database
    • AI meal scanning
    • A plan builder
    • An AI coach
