Drop the bloated spreadsheet. Structure is a native desktop app built for the way you actually train.

100% Privacy-first

Complete Training OS

Weight tracking, progression curves, cycles, MEV — everything one click away.

Your training, on one screen.

A unified dashboard that shows your bodyweight curve, your active block, weekly volume by muscle group, and how close you are to MEV — all on the same surface, all live.

  • Bodyweight & PR tracking
  • Progression curves per exercise
  • Block cycles, 3-week adaptation
  • Live MEV / MRV per muscle group

Ultra fast

Zero loading. Zero friction. Punch your sets between rest sets without the app getting in your way.

Built native. Built local.

No spinners, no “loading workspace”, no web wrapper. Logging a set takes a single keystroke — keyboard-first navigation everywhere.

  • Sub-30ms screen transitions
  • Keyboard-first navigation
  • No background sync stealing focus

  • RPE & feel tracking
  • Auto-links to programme cycle

Frequently asked.

Is Structure really a one-time payment? +
Yes. 17€ once, and the app is yours. Every minor update on v1.x is free. A future v2 may be a paid upgrade — never a forced one.
Does it work offline? +
Completely. Your data lives in a local database on your machine. Notion sync is opt-in and runs only when you ask it to.
Which platforms are supported? +
Windows 10/11. A Linux build is on the roadmap.
Is it only for calisthenics? +
It is designed around calisthenics and street workout, but the programme, logs and most calculators work for any strength athlete who plans in blocks.
How does Notion sync work? +
Connect a Notion workspace once. Structure reads and writes to a small set of databases — quick logs you make on mobile show up in Structure, and your structured plan lives in Structure. Full guide →
Is there a refund policy? +
No. All purchases are final — no refund is issued once your license is activated. See the Terms of service for details.
