Text size

Bigger text in every app

Big Font changes your phone's own text size, so messages, news, settings and almost every other app grow with it.

  • Any size from 50% to 350%, each with a live sample
  • Fine-tune with a slider and watch a real chat message grow
  • Undo straight after every change — no risk in trying
Text sizes 100% to 130% with Apply buttons
Read screen

Hear any screen read aloud

Turn on Read screen and a round blue Read button floats over your apps. Tap it, choose a passage — or the whole screen — and listen while the sentence being read lights up in yellow.

  • Works in messages, news and web pages
  • Choose the reading text size and speed
  • Reads only when you tap — the text never leaves your phone

Magnifier

Your camera becomes a magnifying glass

Point the phone at small print — a medicine box, a price tag, a bill — and see it large on screen.

  • Zoom, light, freeze the picture and high-contrast view
  • Nothing is saved or sent anywhere
Magnifier: use the camera as a magnifier
Read paper

Photograph a letter. Hear it read.

Take a photo of a letter, a label or a bill — or pick one you already have — and the words appear large and are read aloud.

  • Text is recognised on the phone itself, in many languages
  • Keeps your last 10 papers to read again

Call family

Big faces, one tap to call

Add children and grandchildren as big contact cards. One tap calls them — or starts a video call on WhatsApp, Zalo, Telegram or Viber.

  • Contacts are picked one by one — the app never reads your whole address book
Call family with three family members, each with a big Call and Message button
Medicine

Medicine reminders that speak

Set up to four times a day — morning, noon, evening and bedtime — with a note, a photo of the pills or a voice note.

  • Rings even on the lock screen and reads the reminder out loud
  • Missed it? It reminds you again 10 minutes later

Calendar

Today, in really big numbers

See the day and date at a glance, with a second calendar — such as the lunar calendar — underneath. Tap to hear today read aloud.

Apps

Every app in one big, simple list

Large names, a search box and your favourites at the top — no more hunting through small icons.

Flashlight

A flashlight you can't miss

One big switch, three brightness levels, SOS flashing and a screen light. It turns itself off after 15 minutes so the battery is never drained by accident.

Home screen

All the tools on your home screen

Add the Big Font widget and choose up to nine tools. Your most-used tools are always one tap away, without opening the app.

Choosing which tools appear on the home-screen widget

Free, with one optional upgrade

Every tool is free. Big Font shows ads to stay free; a single, one-time purchase removes them for good. Nothing is locked behind it.

Permissions, explained

Big Font asks for each permission only when you open the tool that needs it. Say no, and everything else keeps working.

Modify system settingsText size

Needed to change your phone's text size. Android shows a switch the first time; Big Font shows you exactly which one.
