Free is for one focused workflow
Use Free when you mostly care about one provider, such as Claude Code or OpenAI, and want the number visible without another dashboard.
Pro is for multi-tool builders
Use Pro when your AI bill comes from several tools at once: Claude Code, OpenAI, Cursor, Copilot, Gemini, OpenRouter, DeepSeek, or Mistral.
One payment keeps the app lightweight
Pro is a one-time $7.99 upgrade, not another monthly software bill. That matters for a product whose job is to reduce subscription sprawl.
