Kalcer - Smart Calculator

Kalcer is a calculator designed for shops, stalls, and small businesses. Instead of just crunching numbers, Kalcer understands prices — type shorthand values and it automatically applies your currency multiplier. Link saved items to numbers so every calculation doubles as an itemized receipt.

KEY FEATURES
• Smart Price Calculator — Type shorthand values (e.g., "10" for Rp 10,000 in IDR). Supports addition, subtraction, multiplication, and division with proper operator precedence. • Item Linking — Tap any number in your expression to link it with a saved item. Build an itemized breakdown as you calculate. • Bluetooth Receipt Printing — Connect to any BLE thermal printer (58mm or 80mm) and print professional receipts with your store name, logo, item lines, and total. Print checklists too.
• 20+ Currencies — Pre-configured support for USD, EUR, GBP, JPY, IDR, VND, KRW, PHP, THB, INR, and more. Automatic multiplier brackets (×1, ×10, ×100, ×1000) so you always type the fewest digits.
• Calculation History — Every result is saved and grouped by date. View daily totals and maximums at a glance. Swipe to delete individual entries. • Item Manager — Create, edit, and organize items with names, prices, descriptions, and color tags. Sort by name or most frequently used. • Receipt Customization — Set your store name, address, phone number, logo, and a custom footer note for printed receipts. • Security — Protect your data with a PIN (4–6 digits) and Face ID / Touch ID. Enable delete protection to prevent accidental removal of items and history.
• Multi-Language — Available in English and Bahasa Indonesia, with automatic system language detection.
