Best app to photograph whiteboards — and what to do with the photo.
Short answer
For just capturing a clean whiteboard photo on iPhone, Microsoft Lens and BoardSnap both use perspective correction and produce sharp results. BoardSnap goes further: it feeds the corrected image to AI immediately and returns a summary plus action items in ten seconds, making it the better choice when the photo is a means to an end.
## The photography layer: what actually matters
A whiteboard photo fails when text is illegible. The three main causes:
- Angle — shooting from the side distorts text toward the edges
- Glare — overhead lights reflect off shiny boards and white-out content
- Low contrast — light marker colors on white boards lose detail
Any app using Apple VisionKit (BoardSnap, Notes, Files, Continuity Camera) or Microsoft's Lens engine applies a perspective homography transform — essentially a digital keystone correction — to produce a flat, front-facing image. This solves the angle problem but not glare.
## App-by-app comparison
BoardSnap — VisionKit-powered perspective correction with live quad detection. After capture, BoardSnap AI reads the result and produces a summary + action list. $0 free tier (30 boards), Pro at $9.99/mo.
Microsoft Lens — Whiteboard mode with perspective correction and color enhancement specifically tuned for dry-erase marker on white. Saves to OneNote, OneDrive, or local camera roll. Free. No AI summary.
Apple Notes Scanner — Built into iOS. Same VisionKit pipeline. Saves as PDF. No AI.
Google PhotoScan — Designed for printed photos to eliminate glare. Not optimized for whiteboards.
Plain iPhone Camera — Works fine for well-lit boards where you can stand directly in front. No correction, no enhancement, no AI. Quick and always available.
## Glare: the one thing apps can't fully fix
No app eliminates glare entirely in software — it requires physical angle adjustment. The fix: stand slightly to the side of the direct reflection point and use VisionKit's perspective correction to compensate for the angle. BoardSnap's live quad makes this adjustment visible in real time.
## What happens after the photo
Here's where the apps diverge sharply. Lens, Notes, and the raw camera stop at the image. BoardSnap passes the image to AI and returns structured content. For teams who need the photo as an archive, any of the above work. For teams who need the photo to turn into work, BoardSnap is the only app that closes that loop automatically.
Frequently asked
Does BoardSnap save the original photo?
Yes — the perspective-corrected image is stored within the board record in your project. You can view the original capture alongside the AI summary at any time.
