The month can look fine. The day can still fail.
Timing creates overdrafts. CashGapRadar makes timing visible.
It does not coach, shame, or sell an advance. It reads the schedule you enter and gives you enough lead time to act.
A cause, not a mystery.
Open the day and see every income and payment in order.
A move, not a lecture.
Test a different payment date before changing your real plan.

Rehearse uncertainty
Test the bad month before it happens.
Reduce income. Add a repair. Cut to essentials. Run the scenario against the forecast without touching your real numbers.
Built independently
A forecasting instrument, not another financial account.
CashGapRadar started as a practical way to answer one question: will the timing of upcoming bills create a negative gap before the next income arrives?
The product is deliberately manual and local. Ten minutes of setup replaces a permanent bank connection, daily tracking, and a server holding your financial data.
Privacy you can test
Turn on airplane mode. The forecast still works.
Every calculation runs on the device in front of you. There is no financial account, no bank aggregator, and no analytics inside the app.
Content-Security-Policy: connect-src 'none'This is architecture, not a promise hidden in a policy page.
Open it now. The core forecast, scenarios, and local backup already exist.
The planned mobile launch will be funded directly instead.
Public launch plan
The web app works now. Mobile release happens only if it is funded.
The current PWA remains the proof. Further localization, calendar migration, native notifications, device testing, and store release are paused until the milestones are reached.

Before you spend ten minutes on setup.
Do I need to connect a bank account?
No. There is no bank integration. You enter the balance, income dates, and recurring payments yourself.
Where does my financial data go?
It stays on the device you are using. There is no account, financial server, or cross-device sync. You can export a local backup file.
Do I have to log every purchase?
No. CashGapRadar is a forecast, not a transaction tracker. It uses the income and payments that shape future cash timing.
What is available today?
The original stable PWA is live now. It demonstrates the complete core forecast in its current language, currency, and calendar configuration.
What do the funding milestones pay for?
The $2,000 milestone funds the Android release. The cumulative $5,000 milestone funds the iOS release and completion of the international calendar and currency-display migration for both platforms.
Why not finish the mobile versions first?
The core product already works. Further store-specific work, device testing, notifications, and international migration will continue only if the public launch is funded.
How does Ko-fi funding work?
Support is collected immediately through Ko-fi. The site shows the current public progress toward the $2,000 Android milestone and the cumulative $5,000 iOS milestone. If a milestone is not reached, the corresponding mobile release remains deferred and the working PWA stays available.
