Why it exists

There are thousands of finance and budget trackers, and most of the good ones are paid. My earlier app, Tilted, started as a finance tracker and became a gambling tracker, so Nume is me going back to that first idea and starting from zero.

I had my own reasons too. Logging money in a phone spreadsheet was slow enough that I skipped entries. The apps I tried do not fit how people here handle money, like utang, installments, and paydays on set dates. I did not want my finances in someone else's cloud. And a real app I use every day is the best place to push my mobile UX.

What works today

The build records expenses, income, transfers, and adjustments into an encrypted ledger on the phone. Activity lists every saved record, newest first. A record is never edited in place. It gets a correction with its own date and a required reason, and the original stays in the history. Plans handles bills, installments, budgets, and savings goals. The app locks behind a PIN.

Design choices

Money apps can feel stressful, so Nume stays calm: a deep teal, soft off-white cards, and red only for real problems. Home opens on the month in five big numbers (received, expected, spent, cash left, and budget left), each with a plain definition under it.

Trust comes from being explicit. Labels use plain English. Forms say what is required and what is optional before I type anything. A save is final only after I confirm it, and a mistake gets a correction instead of an edit.

What was hard

Scope. I planned envelopes, reminders, and card accounts before the basics were solid. Android had its own quirks, and designing for myself made it hard to judge what someone else would find clear.

What I gained

Real mobile UX craft: forms, states, errors, and recovery done properly. A ledger also taught me to think in systems, because it forces exact rules and the interface has to follow them. It took patience to test every state before calling it done, and I got a tool I actually use.
