Chronograph³¹

The most useful calendar you ever had was four things on a sticky note, stuck to the edge of a monitor, in somebody's handwriting.

Chronograph is that note, on your home screen, keeping itself current.

Your day arrives as lines of type. The 9:00 with a Meet link on it. The 10:30 you are supposed to bring something to. Lunch. Then a heading for tomorrow, because tomorrow starts somewhere and you may as well see where. Nothing is colour-coded; you already know which one is the dentist.

WIDGETS

Calendar. Upcoming events as a text agenda, gathered under the day they fall on. For anything starting within four hours it also brings up the meeting link, the location, and the one line of notes a person actually typed. Gmail's and Zoom's boilerplate is stripped on the way to the screen.

Time Zones. What time it is in the cities you choose, ordered by offset, each with a small glyph for whether they are awake.

TUNING

Five text sizes, from two large lines to six small ones in the same square. A transparent background that lets the wallpaper through, or a solid card. A default accent plus four colours. Separate toggles for all-day events, multi-day events, time bars, and the free gaps between things.

There are two obfuscation modes as well, Braille and Enigma. They keep your agenda readable to you and not to the person behind you on the bus.

PRIVACY

Chronograph reads the calendar already on your device and draws it. It ships without Android's INTERNET permission, so it cannot open a network connection at all. That is enforced by the operating system, not promised in a store listing. No accounts, no analytics, no ads, no crash reporting.

Requires Android 15 or later.
