About this app

Most PDF apps make you drag a tick around the screen until it sits inside the box. Smart PDF Filler reads the form first, finds every tick box, writing line and signature space, and then puts your mark exactly where it belongs. One tap, done.

It works on the forms people actually get: consent forms, school and club applications, tax and benefit paperwork, medical questionnaires, insurance claims. Scanned and photographed forms too, not just neat digital ones.

YOUR DOCUMENTS NEVER LEAVE YOUR PHONE
The forms you fill in are private: bank details, medical history, passport numbers. So this app was built to never need them. Everything happens on your own device. Nothing is uploaded, there is no account to create, and there is no tracking. Documents you choose to keep are encrypted on the phone and deleted automatically after the time you set. We cannot lose, sell or be hacked for documents we never have.

WHAT IT DOES
- Finds the boxes for you, on digital and scanned forms
- Tap a box to tick it, again for a cross, again to clear it
- "Tick all that apply"? Fill a whole column in one go
- Tap a line and type. Text sizes itself to fit
- Choose the size, the font and bold where you need it
- Your signature, drawn, typed or from a photo, dropped neatly on the signature line
- Today's date in the format you prefer, and your initials, in one tap
- Leave a note for your accountant or solicitor that pops up in their PDF reader
- White out a mistake without leaving a mark
- Save a normal PDF that opens anywhere, with no watermark

OPEN FROM ANYWHERE
Share a PDF to Smart PDF Filler from Gmail, Drive, Files, WhatsApp or wherever it arrived, fill it in, then send it straight back.

PRICE
Free for 2 new documents every calendar month, with every feature included and never a watermark. For unlimited documents, Smart PDF Filler Plus is GBP 2.99 a month or GBP 24.99 a year, with a 7-day free trial. Cancel any time in Google Play; you keep Plus until the period you have paid for ends.

A NOTE ON SIGNATURES
The app places your signature on the document as an image. That is an electronic signature in the ordinary sense, fine for most everyday paperwork, but it is not a certified digital signature. If a document must be signed in a particular way, check with whoever asked you to sign it.

Smart PDF Filler is published by PrintHouse Corporation Ltd, a British company. Questions, or a form it did not handle well? There is a contact form and a help assistant at smartpdffiller.com/support.
It finds the tick boxes and lines, so filling a PDF takes a click, not a fight.
