Things I build outside work, with the source.

(Another) Habit Tracker

Offline and annoying by design.

Picks the topic, harasses me until it's done, blocks my doomscrolling. Nothing did all three, so I built it.

Every tracker I tried would happily count my days. None of them told me what to study, and none got properly annoying late at night. So I built one that does both: it picks the topic, nags until the session is logged, and keeps the score. Reading came later: twenty minutes of a paper book a day, and a shelf of what I finished.

Gets pushier. Reminders nag until it's done.

Home: the greeting, a small planet and one card per habit with its streak

The study habit: today's topic with its guiding questions, stats and recent sessions

Logging a session: how well it stuck, how long, notes

The curriculum: topics covered, area by area

The scroll guard over Instagram: the streak at stake and today's topic

(Another) Reminder App

It knows when I'm at the shop.

Tells me what to buy when I'm at the shop, and what to pay a week before it's due.

I'm always forgetting the grocery list I was supposed to keep in my head. Now the phone tells me when I'm actually at the shop, with the list for that shop. Things with a date get more than one notification: a week before, the evening before, and again until they're done.

Counts down. A compass on Home, and the next date.

Home: the greeting, a compass counting down and what's due now

Home further down: dates with their countdown and the shopping list for one shop

A place: what to do there and its two shops on a map

A yearly reminder for the car tax, with the notification it will send

The places, each with a small map of its spots
