One number tells you what's left to spend today. One envelope holds the big bills — rent, subs, loans. That's it. — — — Left. is a daily budget tracker for people who tried YNAB and gave up, tried spreadsheets and got bored on day three, tried mental math and lost track on day one. It works on a single, honest idea: pour everything you have into a period, set aside the big bills into an envelope, and what remains is yours to spend, divided by days. One screen. One number. No charts. No categories. No streaks, no badges, no nudges. Nothing to maintain. When you need to dip into the reserve — hold the envelope. The envelope breaks open. You take what you need. It seals back. — — — How it works: 01 Pick a period — a month, a week, three days, a trip. 02 Pour in the amount — everything you have for that period. 03 Set the envelope aside — the big bills that have to wait. 04 See what's left — one number on the home screen, every day. — — — What's not in here: — No syncing with banks. — No machine learning categorisation. — No social feed of how friends spend. — No subscription, no upsell, no premium tier. What is in here: — A blank page that opens on a number. — A reserve sealed in an envelope, opened with a long press. — A ledger that remembers every tap. — One hand. One thumb. One number a day. — — — Left. by Koodalabs
