GrappleOS

Training notes with receipts

GrappleOS began as a local dashboard for answering questions that memory handles badly: which positions repeatedly lead to trouble, which submissions are improving, how often a training partner appears in the notes, and whether an apparent trend survives a look at the actual sessions.

The prototype visualises session totals, submissions, positions, partners, injuries, and trends. Filters narrow the view so a period or training context can be examined without losing the underlying entries.

• Session and sparring summaries.
• Submission and position breakdowns.
• Partner, injury, and time filters.
• Charts rendered locally with data stored in the browser.

Why a local prototype came first

Personal training notes are enough to test whether the visual questions are useful before building accounts, syncing, gym features, or a public data model. The local dashboard keeps that experiment inspectable and avoids implying a service exists before its core workflow has earned it.

It also exposes the hard part: the quality of any chart depends on consistent notes. A dashboard cannot recover details that were never recorded or turn a subjective training impression into a clinical measurement.

Vote-to-build means not released

The shelf shows GrappleOS as an idea people can vote for because the personal prototype has not been productised into a supported public application. The screenshots demonstrate the working local direction, not an account someone can sign into today.

Interest will help decide whether the next work should be import tools, a simpler logging flow, deeper analysis, or whether the personal dashboard should remain personal.
