Ferrum is how strength athletes manage their preparation: training, nutrition and blood-work health. Periodized mesocycles, a macro diary, e1RM analytics. No spreadsheets, no notebooks, no fridge-door tables.
// You move the iron. Ferrum runs the numbers.
Features
Training, nutrition and health — one connected system, not three separate spreadsheets.
How it works
No bloat: build the plan, run the cycle, log the work, read the analytics.
A mesocycle: weeks, days, exercises, supersets. Rest cascades: program → personal default → 120 seconds.
The program is frozen into an immutable snapshot: edit the plan all you want, history stays intact. The calendar tracks heavy/light weeks for you.
Weight × reps × RPE — in seconds. Log for any date: forgot yesterday's session? Enter it today.
Epley e1RM per exercise: series by week type, rep-range breakdowns, full history.
Why Ferrum
A typical tracker records what happened. Ferrum manages what happens next.
| Ferrum | Typical tracker | |
|---|---|---|
| Training structure | Periodized mesocycles: weeks → days → exercises | A flat list of logged sets |
| Analytics | Epley e1RM: series by week type and rep range | Before/after history |
| Nutrition | Macro goals for training and rest days, Mifflin-St Jeor TDEE | Just a calorie counter |
| Blood work | Markers, reference-range flags, trends (module in development) | None |
| Supersets | Positions in the day's shared flow, rest between rounds | None |
| Languages | RU · EN · DE out of the box, kg/cm or lb/in | Usually one |

Who it's for
Competing athletes and serious amateurs — people who train by plan, not by mood.
Squat · bench · deadlift. Periodization, percentages and RPE are your native language.
Volume, supersets, macros and weight control in check-ins.
Compound base, custom exercises and a nutrition diary for WODs and life.
Heavy odd-object lifts and custom gear — custom exercises cover it.
Snatch and clean & jerk: weekly loading waves and intensity control.
One to three years in, progress is real but order is not? Ferrum fixes that: program, journal, analytics — instead of ten spreadsheet tabs.
Managing athletes, programs and progress in a single window. In the works.
FAQ
Free during early access — You move the iron. Ferrum runs the numbers.
Yes. During early access everything is free with no feature limits. Paid plans will come later — we'll warn you well in advance.
Your data is yours: export and full account deletion (GDPR cascade, files included). Medical data is saved only after your explicit confirmation on a review screen.
Russian, English and German. Units: kg/cm or lb/in — your choice.
No. Ferrum is a health monitoring and harm-reduction tool: it flags markers low / high / in range strictly by your lab's reference ranges and builds trends. It is not a diagnosis and not a treatment. For medical questions, see a doctor.
No. Ferrum is self-serve: register, build a program, run a cycle, train. A dedicated coach mode is on the roadmap.
