A SIMPLE WORKFLOW
Your form. Three clear steps.
From the document in front of you to a PDF ready to share.
Fill and sign.
Add text and numbers, mark your choices, and draw your signature. Move each addition into place.
Save or send.
Keep an editable project in My documents, or export and share a completed PDF.
THE TOOLS YOU NEED
Less friction. More finished forms.
Clear controls for the everyday work of filling a document.
START WITH A PHOTO
Give your scan a clean start.
Crop the page, align its corners, and adjust light or rotation. Switch between the original photo and Clean scan before you continue.
ADD YOUR DETAILS
Text where you need it.
Tap to add text, then move it into place and adjust its size. Work across the pages of a PDF, one field at a time.
SIGN AND MARK
Your own handwriting.
Draw a signature or add freehand ink, checkmarks, and circles. Move and resize your marks until they sit where you want them.
BOXED FIELDS
One number. Every box.
Enter a complete number into a row of boxes, including leading zeros. Use assisted detection or place the row manually.
KEEP IT EDITABLE
Come back to it later.
Save to My documents to keep your text and marks editable. Reopen the same project and continue where you left off.
FINISH AND SEND
Share a completed PDF.
Export a finished PDF or share it through another app. Preview the result in an available PDF viewer before sending.
INSIDE SIGNMIO
One familiar workspace.
Start with your document, prepare the page, then add what is missing.
Open a PDF, scan a document, or return to something you saved.
Crop, align, adjust light, or rotate with the photo still in view.
Add details and handwriting, then save an editable project or a finished PDF.
These generated previews illustrate the workflow; they are not device captures. Sample names, forms, and signatures are fictional.
GOOD TO KNOW
A few useful answers.
Can I start with a paper form?
Yes. Use Scan document, adjust the photo, then open it in the same editor you use for PDFs.
Does it change the original printed text?
You add text and drawn marks over the document. Signmio does not turn the original printed text into editable text.
What is the difference between Save and Save as PDF?
Save to My documents keeps an editable project with its added text and marks. Save as PDF creates a finished document for viewing or sharing; that exported file alone does not retain editable overlays.
Can I work without an account?
The current app does not require an account to edit documents. Editing and scan adjustments run on your device; sharing or previewing can use another app.
Will it find every box on a form?
Assisted placement depends on the printed layout. Manual placement and adjustment remain available when a row or checkbox is not detected.
Which Android versions does it support?
The current app requires Android 15 or later. The Google Play listing will show compatibility when it becomes available.
