Take control of your money with Otis — the smart, offline-first expense tracker, budget planner, and personal finance manager designed to give you clarity on where your money goes and what you can safely spend.
Most expense tracker apps only show past spending when it’s already too late. Otis goes further by calculating your live "Safe to Spend" balance — deducting your monthly fixed commitments and budget allocations from your income so you never accidentally overspend.
Whether you want to build a monthly budget, track daily spending, save for a dream goal, or export printable PDF statements, Otis makes personal finance simple, private, and effortless.
