There are hundreds of expense tracker apps and they all do more or less the same thing. But oddly enough, not a single one suited my needs, so I developed my own. Through small but targeted adjustments, I've developed the app to become my preferred solution: • Control stays with the user while data entry is greatly simplified: The time between "open app" and "entry saved" has been reduced to a minimum. AI can support this process so that in many cases you wouldn't even need to open the app • AI analysis through LLMs: Instead of developing custom analysis logic, the app prepares your data so it can be used directly in Large Language Models like ChatGPT or Claude: for analysis, forecasts and recommendations • Minimalist design: The app is designed to look beautiful and works without distracting extras • Full control & privacy: No login, no account. Data stays locally on your device. You have complete control over your own database. If you want to share your data with an AI, you decide that yourself Financial barriers shouldn't stand in the way of your personal financial planning with Sum.

You are paying for more than you think. Subtotal adds every subscription up into one figure — what leaves your account each month, and what that comes to in a year. Then it warns you days before each renewal, on your phone and by email, while cancelling can still stop the charge. No bank connection, no scraping: you enter what you pay for, and the app does the arithmetic. WHAT IT DOES • One honest total — every subscription added up, by month and by year, in your own currency. • Renewal reminders days ahead, on your phone and by email, so no charge lands unannounced. • A calendar of every payment coming up, so renewal day never collides with payday. • Where the money goes: by category, by plan and by payment method, ranked by yearly cost. • Price history — every rise kept on record, and a warning before the next one. • Free trials tracked to the day they convert into a real charge. • Shared plans split properly, so you only ever count your share. • Any billing cycle — weekly, monthly, quarterly, yearly, or an interval you set yourself. • Multi-currency, converted into one home currency you choose. • A yearly review: your heaviest month, your biggest category, and what you cancelled. SUBTOTAL PRO Unlimited subscriptions, spending trends, budgets, the savings tracker, home-screen widgets, calendar sync, CSV import and export, and an app lock. Free covers up to 5 subscriptions with full totals and reminders — nothing is ever deleted if you stop paying. No ads, no trackers, nothing sold. Your ledger lives in your own account and syncs to your own devices, and you can delete it and everything in it from inside the app. Subtotal is a ledger for money that leaves on a schedule — subscriptions, memberships, insurance, the gym, the mobile plan, the streaming you forgot about. If it charges you again next month, it belongs here.
