Yahora is a minimalist event logger. You give a recurring event a name, and from
then on a single tap on its chip records the date and time it happened. No
intermediate screen, no confirmation dialog, no extra fields to fill in.

Most tracking apps grow into note-taking tools: nested categories, custom
fields, reminders, dashboards. Yahora deliberately does not. A tag has a name, a
favourite flag and, if you like, a colour; an entry has a timestamp. That is the
entire model, and the design goal follows from it — recording an event should
cost one tap and zero attention. That simplicity is the point, not a step on the
way to something bigger: nothing here is designed to keep you in the app or to
bring you back to it.

What it does

* Tag cloud — chips flow across the screen, each as wide as its name and all
sharing one type size, sorted alphabetically. Favourites are marked with a
star, which changes the emphasis but never the order.
* One-tap logging — a short tap records the current timestamp right away, with
a haptic tick as confirmation, and offers to undo it from its own snackbar.
* Long press for everything else — rename a tag, mark it as a favourite, or
browse its history. Actions that do not apply are hidden, not greyed out.
* Colour, if you want one — any colour you pick, as a tab behind the chip.
* History as a tree — months, then days, then the individual entries at
HH:mm:ss. Each branch says how many children it holds.
* Statistics — how many times each tag was logged, by year and month. Pick
tags to add them up together. Numbers you read at a glance, no charts.
* Backup — save the whole log to a file you choose, and restore it on this
phone or a new one.
* Safe by construction — a tag that holds entries cannot be deleted, so a
history is never lost by accident. Old entries go only in whole months,
days or tags, after a confirmation that says how many.

Privacy

Yahora is fully offline. It declares no network permission, so it cannot reach
the internet even by accident: no accounts, no analytics, no advertising and no
third-party libraries beyond Android's own. Everything you log stays in the
app's private database on your device, unless you save a backup file yourself.
