Still tracking travel expenses in a notes app? Viatren is an AI-powered travel budget manager. Snap a receipt and it auto-reads the amount and category. Convert multiple currencies with live exchange rates. Analyze spending patterns and stay on budget — for both leisure trips and business travel. --- Key Features --- ◆ AI Receipt Scan Take a photo of any receipt and AI automatically extracts the amount, date, merchant, and category. Works with foreign receipts too. ◆ AI Quick Input Type naturally — like "Ichiran ramen ¥1,200 cash" — and AI parses the amount, category, and payment method for you. ◆ Business Trip Mode Manage work travel expenses separately with dedicated categories: per diem, registration fees, local transport, Wi-Fi rental, food, souvenirs, and more. Track reimbursable expenses at a glance. ◆ Multi-Currency & Live Exchange Rates Supports KRW, JPY, USD, EUR, THB, GBP, AUD, and more. Rates update automatically, and all expenses are converted to your base currency. ◆ Flight Number Auto-Setup Enter a flight number (e.g. KE123) and the destination, trip title, currency, and exchange rate are set automatically. ◆ Budget Tracking & Forecast See your budget usage in real time. A burn-down chart and forecast show how much you can spend per day for the rest of your trip. ◆ Expense Map See where you spent and how much — right on the map. Search for a place when logging an expense and the category is suggested automatically. ◆ Statistics & Insights Category pie charts, daily spending bar graphs, and trend analysis. Smart insights detect unusual spending and suggest ways to save. ◆ Trip Retrospective Report After your trip, review an AI-generated retrospective: top 3 categories, biggest expense, daily average, and payment breakdown. --- More Features --- • Home screen widget — check your travel budget at a glance • Trip start reminder — push notification on departure day • Calendar heatmap — daily spending color-coded • Display currency — show budget in a different currency • PDF report export • Manage multiple trips at once (upcoming / ongoing / completed) • Meal type tracking (breakfast, lunch, dinner, snack, dessert) • Payment method management • Data backup, restore & delete • Timezone-safe dates • Dark mode support • English, Korean, and Japanese support Core spending data is stored locally on your device.
