About this app

Stop Guessing. Start Spending Confidently.

Ever checked your bank balance and wondered, "Can I actually afford this today?" Most budget apps tell you what you spent yesterday. Koyna tells you what you can safely spend today.

Koyna is a next-generation personal finance manager designed to remove the anxiety from daily spending. Whether you are a salaried employee, a freelancer, or a bit of both, Koyna calculates your "Safe-to-Spend" limit in real-time, taking into account your upcoming bills, savings goals, and income patterns.

KEY FEATURES:

✅ The Safe-to-Spend Engine: No more complex spreadsheets. Koyna looks at your balance, subtracts your committed bills and savings targets, and gives you a single, daily number you can spend without guilt.

🧠 Emotion-Based Tracking: Do you impulse-buy when stressed? Koyna is the first app to track the emotion behind every expense. Understand your patterns of regret and joy to make better financial decisions.

📈 Regret Score & Analytics: See your "Regret Score" trend over time. Identify which categories (like fast food or late-night shopping) cause the most stress and get actionable insights to improve your relationship with money.

💼 Multi-Mode Income Support:

Salary Mode: Automatic countdown to payday with daily burn-rate calculations.
Freelance Mode: Built-in Tax Vault that automatically sets aside taxes from every payment, so you’re never surprised at tax time.
Hybrid Mode: The best of both worlds for those with a side hustle.
🔒 Privacy First: Your data stays on your device. Sync to your personal Google Drive for total control and privacy. No ads, no selling your data.

WHY KOYNA? In a world of complex financial tools, Koyna keeps it simple. We don't just track numbers; we track how those numbers make you feel.
