What it does

Workout logging

Log sets as you go, with a rest timer, personal records and a progression suggestion based on what you actually lifted.

An exercise library

799 movements with cues, muscle targets, equipment requirements and research notes that cite their sources.

Plans

Build the days you train and the sets on each — straight sets, pyramids, drop sets, supersets — written out as real numbers.

Food diary

A bundled USDA food database, searchable offline, with servings and macro targets you set yourself.

Progress

Measurements with charts, progress photos with side-by-side comparison, and goals that follow your readings.

Lab results

Type in a panel from a report. The app records what your laboratory printed — it supplies no reference ranges of its own.

Reports

Training, nutrition and body summaries over any period, exported as a real PDF you can print or hand to a coach.

Tools

Interval timer, stopwatch, plate calculator, one-rep-max estimates, body calculators, pace and unit conversion.

Coaching

An optional second workspace for clients, sessions and notes, kept strictly separate from your own training.

What it looks like

Screens from the Android build, unretouched. The desktop builds show the same information in a wider layout.

The Today screen: a greeting and date, a training card showing the last session was three days ago with a Start button, food today reading 2316 of 2400 kcal, body weight 83 kg, and a goal of getting down to 80 kg. — **Today**The day in front of you: the last session, food against your own target, current weight, and any goal in progress.

The Train screen: a card to start an empty workout, links to Plans and to the exercise library of 799 movements, and a list of recent workouts with their dates and durations. — **Train**Start an empty session, open a plan, or go to the library. Recent workouts sit underneath.

A finished workout: 66 minutes, 3 exercises, 9 working sets, 3615 kg of volume, then each exercise with the load and reps of every set written out. — **Workout review**What you did, written out as numbers: duration, working sets, volume, and the load and reps of every set.

The Nutrition screen for a single day: 2316 of 2400 kcal with protein, carbohydrate and fat bars against their targets, then breakfast, lunch and dinner with each food, its serving and its macros. — **Food diary**The day's meals against the targets you set, with the macros of every entry from the bundled USDA database.

A body weight chart over three months showing a downward line, labelled with the change in range, a trend of minus 0.5 kg per week fitted to 25 readings, and the range covered, followed by every individual reading. — **Body weight**Your readings plotted, with the trend line and the number of readings it was fitted to stated on screen.

The Progress screen with tabs for Measurements, Photos, Goals and Lab results, listing body weight and waist with sparkline charts and other measurements marked as not recorded yet. — **Progress**Measurements, photos, goals and lab results, each over whichever period you pick.

A report over three months: observations such as 2.5 sessions a week counted across 91 days, food logged on 13 of 91 days, and a bench press stall, each with the count it came from, followed by training totals and an Export PDF button. — **Reports**Counts taken from your own records, each saying what it was counted over, and a PDF if you want one.

The exercise library: a search field over 799 exercises and an alphabetical list, each row showing the movement pattern, the level and the impact. — **Exercise library**799 movements, each tagged with its pattern, level and impact, searchable by whatever you call it.

The Arnold Press page showing an illustrated figure pressing two dumbbells overhead, with playback controls stepping through the frames of the movement. — **Exercise detail**An illustrated demonstration for the movement, with the muscles worked, the equipment and the set-up underneath.

The Tools screen listing an interval timer, stopwatch, plate calculator, one-rep max estimates, body calculators, pace and speed, and a unit converter, each with a one-line description. — **Tools**The everyday arithmetic of training, including a one-rep max that shows the spread between formulas rather than one figure.

The Knowledge screen: searchable articles grouped under Getting started and Training principles, each carrying an evidence label such as Established or Moderate beside its title. — **Knowledge centre**Training and nutrition explained, with the strength of the evidence labelled on every claim.

What it does not do

There is no server, so there is nothing to leak.

No account. No sign-up. No analytics, no telemetry, no crash reporting, no advertising, no tracking. The application makes no network request at all unless you switch one on, and the two switches that exist are off until you do.

Your workouts, food, measurements, photos, medical notes and lab results are stored in a database on your device that only this application reads. Backups go where you put them.

No account No sign-up No analytics No telemetry No crash reporting No advertising No tracking No subscription

Where the numbers come from

Anywhere the application estimates something, it says so, names the method, and shows the disagreement between methods rather than one confident figure. Where research supports a claim, the citation is on screen. Where it does not, the application says that instead of inventing one.

Energy expenditure is offered through several published equations at once, so the spread between them is visible.
One-rep-max estimates list every formula and the range they cover.
Lab reference ranges come from your laboratory, never from the app.
Averages are taken over the days you actually logged, never over days you did not.

Free, and staying that way

Prime Edge Systems costs nothing, has no subscription, no paid tier, and no feature held back. If it is useful and you want to put something toward it, there is a donation link — and nothing in the application changes whether you use it or not.

Support the project

One-off, entirely optional, and it unlocks nothing — because there is nothing locked.
