A single-purpose app for field markup. Straighten skewed photos with corner-pin correction, then add lead lines, text and dimensions in the fewest taps.
FieldCue is a single-purpose app for finishing field-instruction photos right on your phone.
Photos' built-in perspective tool crops the image into a straight rectangle, but it can't reshape each corner independently. FieldCue adds that missing piece: corner-pin correction that moves all four corners on their own, straightening skewed edges in seconds. From there, add lead lines, text notes, and dimension lines in the fewest taps possible.
HOW IT WORKS
1. Place - Rotate the photo with two fingers to level it against the on-screen grid.
2. Warp - Drag each corner freely to square up the shot.
3. Crop - Trim to any ratio, keeping just what matters.
4. Annotate - Draw a lead line from the spot you want to mark, release, and type.
5. Dimension - Draw a line to measure, release, and enter a number.
6. Save - Crop in, choose your text size, and save straight to your camera roll.
No app UI ends up in the saved photo - just the straightened image with your notes and dimensions, ready to send by email or text exactly like you always have.
SPECIAL FEATURES
- Search what you write: tap the search icon on any note to look up a part or model number in the built-in browser, without retyping it.
- Save up to 20 in-progress files, with thumbnails sorted newest first.
- Launch straight from your camera roll: share a photo from the Photos app and open it directly in FieldCue.
Built for construction sites, retail displays, furniture layout, and any job where you need to straighten a photo, mark it up, and send it - fast.
One-time purchase, no subscriptions, no ads, no in-app purchases. iPhone only.
