Dravin Budget

Dravin Budget is an offline expense tracker and personal budgeting journal
wrapped in a Chinese New Year theme: deep imperial red, gold lanterns, and a
dragon that hoards the money you do not spend. Every expense you log, every
no-spend day you keep, and every month you finish inside your limit feeds the
dragon and moves it towards its next evolution. It is a budget app for people
who bounce off spreadsheets — the numbers are all there, but the reason to open
it every day is the creature you are raising.

Set it up once. Name yourself the Keeper, choose your currency, enter your
starting balance and a monthly spending limit, then tap the egg three times to
hatch your dragon. From then on the home screen is your treasure hoard: current
balance, how much of this month's limit you have spent, today's date in the
Chinese calendar, and a daily piece of dragon's wisdom. Adding an expense takes
one tap and a few numbers on a purpose-built keypad — pick a category, set the
date, add a note if you want, done. Topping up your treasure works the same way.

KEY FEATURES
✓ Expense and top-up tracking — a fast custom keypad, seven built-in categories
and your own custom ones, with an optional note on every entry
✓ Monthly limit with a live progress bar — see exactly how much room is left
before the month runs out, not after
✓ Spending calendar — a month grid that marks every day you spent and every day
you did not; tap any day to see what went out
✓ Analytics that actually read — a category donut, daily spending bars, a
cumulative curve and your top five categories, all for the month you pick
✓ The dragon — ten evolutions from Hatchling to Eternal, an XP bar, a no-spend
streak counter and your longest streak on record
✓ Eleven achievements — first offering, three-day and thirty-day streaks, a
month finished inside your limit, a hundred logged transactions and more
✓ Search and filter — find any past entry by note or category, month by month
✓ Fully offline — no account, no sign-in, no ads, no network access at all

HOW IT WORKS
1. Hatch your dragon and set your currency, balance and monthly limit.
2. Log each expense as it happens — amount, category, date, note.
3. Watch the limit bar, the calendar and the charts fill in as the month runs.
4. Earn XP: +5 for logging an expense, +10 for a no-spend day, +25 for every
seven-day streak, +50 for a month finished inside your limit.
5. Evolve the dragon, unlock achievements, and start the next month knowing
exactly where the last one went.

WHY DRAVIN BUDGET
Most budget apps ask for your bank login and then show you a spreadsheet.
Dravin Budget asks for nothing. Everything lives on your phone, the whole app
works in airplane mode, and the reward loop is a dragon rather than a guilt
notification. The design is its own — hand-drawn lanterns, gold-on-crimson type
and a treasure card instead of a balance row — and every screen was built for
one thumb.
