Training + nutrition

One app.
Two halves
of a day.

Iron logs the lift. Tonic logs the food. One tap between them, and the numbers stay on the same day. Log it on your own, or run a club and read twelve clients' weeks the same way.

Who logs

Same app, two
ways to use it

On your own

Nobody to report to

You build the routine, you set the macro plan, Coach reads your own log back to you. Nothing is shared unless you invite someone in — and you can leave a club without losing a single entry.

Your routines
Built once, reused every push day
Your macro plan
Targets you set, moving with training load
Coach
The only second opinion, unless you add one
Private by default
No club, no coach, no shared log
Iron

The set grid,
and nothing else

Build a routine, start it, tick boxes. The live session shows what's left and how long you've been in the gym — 24:18 elapsed, 4 of 6 exercises. Rest timers you can skip. Records marked in gold, once, and never mentioned again.

Routines
Reusable day templates — push, pull, legs
Exercises
Last weight, last reps, or Never
Muscle volume
Sets and kilos per muscle group, per week
Garmin sync
Sessions land on the watch's calendar
Photograph it
A plate, a shelf, a menu. Estimates come back with their doubts attached.
Or describe it
"Big bowl of pasta, some parmesan." That is a complete entry.
Or reuse it
The breakfast you eat five days a week is two taps, forever.
My plan
Targets that move with your training load, not with your weekday.
Tonic

Log the meal
in ten seconds

Three ways in — photo, sentence, saved meal — and one macro plan behind them. Tonic would rather have a rough entry today than a perfect one you never made.

The logging contract

Coarse logging
is still logging

Give or take ~450 kcal across today's four meals. We print the range instead of inventing a midpoint, and we never offer to help you make it back. A light training week is a deload, not a failure.

1,800–3,200
A range stays a range. No fake precision on a day you ate out twice.
Sauce unclear
Where the data is uncertain, the entry says so in two words.
Lead with the week
The morning after a big evening, you get seven days of context. Not a verdict.
Coach

Answers that
read your log

Coach sees the same sets and meals you do, so the reply is about your week rather than about nutrition in general. Ask in a sentence; the answer expands in place.

Am I under on protein? Is my pull volume low? What should I eat tonight?
This week's read

Three sessions, 18,400 kg, and protein averaged 132 g against a 165 g target. Pull volume is the thinnest column — two more rows of pulling on Thursday would even the week out.

Clubs · for trainers
A roster, not a
chat thread

Clubs are the trainer half of Iron & Tonic. Invite clients by code, assign routines and macro plans, and read each week as the same cards they see. Clients keep their account when they leave.

One club, one roster

Recipes
Typographic cards, macros first — log a portion straight into the diary.
Scan products
Barcode in, label out. Where the pack is vague, the entry says so.
Macro plan & goals
Set a fitness goal, get protein, carbs and fat targets that follow the block.
Everything else
