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.
