Lucky Master – Loan Calculator and Payment Tracker

Lucky Master is a personal loan calculator and tracking tool. Add loans manually, run amortization calculations on your device, save records locally, review payment schedules, and mark due dates on a calendar. Lucky Master does not connect to banks, lenders, or external financial services.

📊 LOAN CALCULATOR

Enter principal amount, annual interest rate, and loan term in months or years. Add an optional name, set a start date, and tap Calculate. Lucky Master applies standard amortization formulas to display monthly payment, total interest, total amount paid, projected payoff date, and term length. Review the summary screen, save the loan to your list, or open the full payment schedule before saving.

📋 LOAN LIST

The Menu screen shows each saved loan as a card with name, principal, monthly payment, and progress count of marked payments versus total term. Tap a card for full details. When no loans exist, Lucky Master prompts you to add your first entry. Use + New Loan anytime to create another record. All information is stored locally on your device and remains available without an internet connection.

📑 PAYMENT SCHEDULE

View the amortization table from calculation results or from any saved loan detail page. Columns include payment number, date, payment amount, principal portion, interest portion, and remaining balance. Rows reflect paid status when you mark dates on the calendar. Long schedules load in segments through a Load More button for comfortable scrolling on mobile screens.

📅 PAYMENT CALENDAR

Open Calendar from the bottom navigation bar. Select a loan from the dropdown when tracking multiple entries. Move between months with arrow controls. Due dates are highlighted; dates marked as paid use a separate color. Tap a due date to switch between paid and unpaid. A legend identifies due date and paid markers. The calendar is a visual tracker only and does not send notifications or alerts.

🔍 LOAN DETAILS

The detail screen highlights monthly payment and shows principal, interest rate, term, start date, and payoff date. A progress bar reflects how many payments you marked compared with the full term. From this screen open the schedule, open the calendar, edit parameters, or delete the loan after confirmation.

✏️ EDIT AND DELETE

Edit reloads the calculator with current values ​​so you can change name, principal, rate, term mode, or start date and recalculate. Saved payment marks stay attached to the loan when you edit other fields. Delete removes the entry from your list permanently.

🎨 MOBILE INTERFACE

Lucky Master features a dark layout with neon accents, large touch targets, and bottom navigation with Menu and Calendar tabs. Content scrolls vertically for one-handed use on phones.

🔒 LOCAL STORAGE

No sign-in required. Calculations and saved data run and stay on your device. Lucky Master stores loans in local storage until you delete them.

⚠️ PLANNING TOOL

Lucky Master provides estimates for personal planning and organization. Results depend on the values ​​you enter. The app is not a bank, lender, broker, or financial advisor. Always verify figures with your loan documents and qualified professionals before making financial decisions.

Whether you track one vehicle loan or several personal loans, Lucky Master combines calculator, schedule, calendar, and progress tracking in one app. Add a loan, review the numbers, save it, mark payments on the calendar, and follow your plan until payoff.
