Pillar 1 of 3

Train

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

~870
exercises, with faceted search and your own custom entries
8 + 5
logging types and set types, supersets and dropsets included
8
rank tiers per exercise, from Bronze to PEAK, normalised for bodyweight
2
calculators — plate maths and warm-up ramps, worked out for you

Ranks are computed from your own estimated one-rep max. No percentiles, no leaderboards. Stop training a lift and it goes quiet and keeps its peak — it is never marked down.

Try the plate calculator

Pillar 2 of 3

Fuel

Intake tracking with the reasoning attached to every target.

2
open databases behind it — USDA FoodData Central and Open Food Facts
~30
micronutrients, each with its derivation and a real citation
21,209
menu items across 96 restaurant chains
0
photos uploaded — barcode and label scanning run on your device

Scanning is unlimited on every tier, including free, because it runs on your phone rather than on a server we pay for. Exercise calories never enter the budget, and no food gets a verdict.

Pillar 3 of 3

Build

Habits you design, at a cadence you pick.

5
cadences — daily, chosen days, N times a week or month, every N days
1
momentum score that dips when you miss and never resets to zero
0
fixed challenges, 21-day plans or prescribed quests
—
habits you are dropping, tracked as days clean instead

Stacks chain a new habit onto an anchor you already keep. A missed day is recorded and left alone — there is no scolding, and no consolation either.

01 — At the bar

Pick the weight.
See the plates.

One less calculation between sets. Change the target and see exactly what goes on each side.

Try the app’s plate calculator here. Switch between kilograms and pounds, or move through the weights with the slider.

Try it

Load the bar

This is the calculator from the app, running in your browser. Pick a weight and it loads the bar, heaviest plates first.

Per side: 25 + 15 kg 100 kg on the bar

02 — Why you can check it

It shows its work

Open a target. Read the reasoning. Decide what to use.

A number you can inspect

The protein target opens into an explanation, an editable value and the research behind it. The example shown is from a demo profile.

  1. Understand the starting point. Read what the target is based on.
  2. Inspect the evidence. Follow the source from the explanation.
  3. Make a choice. Keep the suggested value or enter a custom target.

03 — Privacy

Quiet by default

Your training, food and habit data is written to your device first. Turn on cross-device sync and it’s also stored with our backend provider under row-level security, reachable only by your authenticated account.

  1. No ads, and no advertising SDKs.
  2. Nothing sold or shared for cross-context advertising, to anyone, ever.
  3. Your data is never used to train a model, and no third-party model is used.
  4. Product analytics are off until you turn them on, and carry no device or account identifier.
  5. Barcode and label scanning happens on your device; those photos are never uploaded.
  6. Apple Health readings stay on your device and are never sent to our servers.
  7. Export to CSV, and delete everything, whenever you want.

The specifics — including what our providers see and where they are — are in the Privacy Policy.

04 — Cost

How the pricing works

What runs on your phone is unlimited

Logging, routines, habits, streaks, charts, ranks, coverage analysis and scanning all run on your device. They cost us nothing per person, so they are not metered — on any tier. What runs on servers we pay for by the request is the only thing that ever carries a limit.

A gate covers authoring, never evaluation

Paid features decide whether you can build or edit something — never whether what you already built keeps working. If a subscription lapses, your existing setup keeps running and only the editor locks.

Paid adds, it does not carve out

Nothing that works today moves behind a payment later. When the first paid feature shipped, the free tier got better in the same release. Your progress is yours, and is never held back to make a point.

The price funds the work

There are no investors to repay and no advertising. Every exercise is individually researched and written up rather than scraped, and that is an ongoing cost. We commit at least a quarter of subscription revenue to product development each year.

05 — Roadmap

iPhone first. The rest pays its way.

ReInvent ships in order. Each step starts when the one before it can pay for it, so nothing below is promised on a date.

  1. Next

    Step 1: iPhone

    ReInvent launches on the App Store first, with everything on this page: Train, Fuel and Build, and the Free and Pro plans.

    Waiting on the App Store listing.

  2. After iPhone

    Step 2: Android

    The Android app already runs in internal testing. It goes to Google Play once early revenue covers the Google Maps service its restaurant maps depend on.

    Starts with the first revenue from the iPhone release.

  3. Funded by revenue

    Step 3: Paid for by revenue

    Some features cost money every time they run: licensed data, server time, model usage. They arrive as income can cover them, not before.

    • Improved workouts Deeper training tools, built on the logging that ships at launch.
    • A larger food database Licensed nutrition data, restaurant menus included, beyond the free public sources used now.
    • AI meal scanning Photograph a plate to start an entry you can check and correct.
    • Plan builder Help laying out a training plan from your goals and schedule, with AI assistance added later.
    • AI coach Questions about your own training, food and habits, answered from what you log.

    Built in roughly this order, as revenue allows.

Later: Meal plan helper, planning meals ahead, after the features above.

No dates, and none of these are in the app yet. If the order changes, this list changes with it.

Status

Not out yet.

ReInvent launches on iPhone first, and Android follows on Google Play soon after. There is nothing to download today — this page is where the links will appear.

  • Coming soon App Store iPhone
  • After iPhone Google Play Android

The order, and what comes after it, is on the roadmap.
