Organize by property and category, set a build budget, and see totals, breakdowns, and cumulative spend over time. Export CSV or PDF when you need a report. Optional iCloud sync keeps your data backed up across your devices. Face ID / passcode lock is available if you want extra privacy. No account required. No ads. Your expenses stay on your device (and in your iCloud if you enable sync).
