## What is 1Lens?

1Lens is a metacognition practice and reflection tool. Choose a mental model you want to work on, record your decisions and actions in everyday situations, and look back on what changed.

• Practice mental models: Start with built-in models such as First Principles, Win-Win Thinking, and Growth Mindset, or create your own. Keep up to three models active to stay focused.
• Record wins and misses: Note what went well or where you fell short. Make a specific “If…then…” plan for your next attempt.
• Reflect with voice: Record your thoughts and, when supported by the device, transcribe them with Apple’s system speech recognition. Recordings, transcripts, and practice entries stay on your device.
• Review your progress: Browse recent daily entries and reflection history, and use your practice streak to notice your rhythm.
• Make it yours: Edit or archive models, then reactivate them from the full list whenever you are ready. Optional reminders can help you build a routine.

Take a moment to notice how you think, then choose what to do next.

Microphone access is used to record voice reflections. Speech recognition access is used for on-device transcription. Recording starts only when you choose to begin.
