About this app
DisparaTimer is a mobile app that, when connected to a Raspberry Pico W/WH, can control the exposure time of a photographic enlarger using a power relay. The physical setup is inexpensive and easy to assemble. DisparaTimer has two operation modes. The first is a traditional timer mode, where you set a specific time for each exposure. The second is designed for creating test strips with constant fractional step increments over a base time. On iPad (iPadOS 17 and later), DisparaTimer includes a landscape-only notes panel that lets you add photos or images of your test strips and make handwritten or visual annotations directly on them.

Here’s what’s new: Notes system (new): • Added a full Notes panel inside the app. • Create, rename, and manage multiple notes. Image annotations (new): • Added a built-in photo annotation system. • Works with both finger and Apple Pencil. • Includes a clear annotations option to start over anytime.

Si me dices el nombre exacto que usas en la app para esa sección (“Notas”, “Cuaderno”, “Darkroom Notes”, etc.), te lo ajusto para que suene todavía más “marca DisparaTimer/Color Timer”.
