Things I’m building.

Apps, tools, and experiments. From keeping a training record to finding a way through a story, or exploring a house before it exists.

Longwork

A durable record of the work you put in.

An Android app for strength training, cardio, food, and body weight. Keep your record on your device, without an account.

Explore Longwork

Plan and train: Create a programme or import a supported spreadsheet. Record sets, use rest timers, and log cardio.
Keep the wider picture: Track food and body weight, review exercise history, and return to the workouts behind your records.
Keep your data: Core logging works offline. Export a backup and restore it when you need it.
