About this app

Wish your everyday handwriting was clearer and more consistent? Whether you're a journaler, student, or anyone who takes pride in their penmanship, Penna helps you rediscover the art of writing by hand.

Penna isn't a calligraphy critic, a font generator, or another tracing app. It's a coach for everyday legibility — built on computer vision, not graphology pseudoscience. Snap a photo of your handwriting and get instant, actionable feedback to help you write more clearly.

How it works
1. Capture: Take a photo of a few lines of your handwriting on any paper.
2. Analyze: Penna reviews letter shapes, spacing, and baselines in seconds.
3. Improve: Get an overall legibility score and specific tips to refine your writing.

Key features
• Instant legibility scoring: A 1–10 score across five dimensions:
– Overall legibility
– Letter consistency
– Spacing
– Baseline alignment
– Stroke quality
• Personalized feedback: Concrete, encouraging advice pinned to specific words. Penna tells you exactly what to adjust for maximum impact.
• Targeted practice: Every analysis suggests a focused exercise designed to address your primary improvement area.
• Annotated photo: When available, a red-pen style overlay on your photo highlights specific characters and spacing issues.
• Progress tracking: Save your analyses to a personal history and watch your scores improve over time.

Who Penna is for
• Adults reclaiming their flow with pen and paper, or anyone who wants more readable journals and notes.
• Students improving exam readability and the clarity of study notes.
• Anyone who finds writing by hand calming or grounding, and wants to enjoy it more.

Why Penna?
Most handwriting apps focus on tracing letters or graphology pseudoscience. Penna is different. It uses computer vision to provide real, constructive feedback based on the mechanics of clear communication — honest, warm, and designed as a calm, supportive space for your practice.
