A pellet heating log for boilers without sensors or integrations. You record every time you top up the pellets, and the app calculates real consumption and shows how the boiler settings affect it. Stock tracking estimates how many pellets are left and how long they will last. Maintenance keeps cleanings, servicing and repairs in one place, and with a schedule set, the app reminds you of upcoming dates. A full backend and an attempt at a local-first architecture are planned.

A graphics card price tracker covering the largest Polish stores. Prices collected automatically three times a day build a history for every model, and the analysis view compares the minimum, median and maximum price against MSRP, making it easy to tell whether a card is overpriced. Launched in January 2022, at the peak of the GPU pricing crisis, and still running today.
