Mobile guide · Part 1 of 5
BlindBox Mobile overview
BlindBox for iPhone and Android is the same accessibility-first email app, shaped for touch, VoiceOver and TalkBack. It adds two ways to use mail that are made for the phone: Block Mode and Voice Mode.
In this part you will learn
- What BlindBox Mobile can do
- The screens you will use every day
- How your mail reaches your phone
What BlindBox Mobile does
All your mail in one app
Gmail, Outlook, Apple Mail (iCloud), Yahoo, ProtonMail through Bridge, and other IMAP accounts. Read them one at a time or together in All inboxes.
Straight from your phone
The app talks to Gmail, Outlook or your IMAP server directly from the phone. Your mail is not routed through a BlindBox mail server.
Block Mode
A large-tile mailbox designed for screen readers, with one clear action per tile. Switch it on from the menu.
Voice Mode (beta)
Handle mail by talking in ordinary sentences: “read my latest email”, “reply that I will be there”. Anything risky asks you to confirm first.
All Files
A tab that turns every attachment into one list you can sort, filter and search.
Hear images and PDFs
Describe or transcribe attachments and the pictures in an email. Your remaining AI reads for the month are shown as you go.
Blind Sight and full visual control
Hide the screen for privacy, or tune text size, contrast, spacing, themes and colors for low vision.
Fast, even on a weak signal
Recent messages and bodies are kept on the phone, so your inbox opens instantly and recently read mail is there offline.
The screens you will use every day
A phone cannot show everything at once, so BlindBox gives each job its own screen and always gives you a way back.
Mailbox
The home screen. Across the top: the menu button, the folder name (activate it to jump to the first message), Compose, Refresh and an optional Guide button. Below that, the Messages and All Files tabs and the search field.
Menu
Opened with the menu button. From the top: your free trial status, your mailboxes and All inboxes, the Block Mode switch, folders, labels, a row for each Settings tab, Voice Mode, and Back to top.
Message
Opens over the mailbox with the message, its attachments and its actions: Reply, Reply all, Forward, Star, Archive, Print, Delete, Report spam, Read aloud and more.
Settings
Seven tabs: Account, Accessibility, Layout, Appearance, Payments, Support and Guide.

Where your mail goes
- Mail stays between you and your provider. The desktop app runs a small mail engine on your own computer; the phone app talks to Gmail, Outlook or IMAP directly from the phone.
- The BlindBox service holds your BlindBox profile and plan, and helps finish Google or Microsoft sign-in. It does not keep a copy of your mailbox.
- AI only when you ask. A file you send to Insight, or a question you ask Email AI along with the message excerpts it needs, is sent for that one request and processed by Google Gemini. Phone Voice Mode speech is processed by Groq.

Setting up BlindBox Mobile
Connecting your first mailbox takes a few minutes. Every step is announced to your screen reader, and you can change the app language on the very first screen.
In this part you will learn
- How to connect each kind of mail account
- Why Apple and Yahoo need an app password
- Adding more mailboxes and a calendar
Step by step
- WelcomeSign up, or log in to your BlindBox profile
- Choose providerGmail, Outlook, Apple Mail, Yahoo, Proton or Other
- Sign inYour provider’s own sign-in, or an app password
- BlindBox profileCreate it to start your 14-day trial
- InboxYour mail, ready to read
Step 1: Start on the Welcome screen
Choose your language at the top, then pick Sign up to connect your first inbox. If you already have a BlindBox profile, choose Login With BlindBox Profile instead.
Step 2: Choose your mail provider
Pick Gmail, Outlook, Apple Mail (iCloud), Yahoo, ProtonMail or Other. Your screen reader hears each step’s instructions as you arrive.
Step 3: Sign in to your mail
What you see next depends on the provider — see the table below.
Step 4: Create or log in to your BlindBox profile
Your profile holds your plan and the settings that follow you between devices. Creating it starts your 14-day free trial.
Step 5: Land in your Inbox
BlindBox opens your default mailbox. Open Settings early to set text size, read aloud, Blind Sight and the folders you want in the menu.
Provider by provider
What the sign-in step looks like for each kind of account.
Gmail
Sign in on Google’s own page. BlindBox never sees your Google password. Calendar access is requested at the same time so invitations can be added.
Outlook
Sign in on Microsoft’s own page, or choose “Use email & password instead” if your account works that way.
Apple Mail (iCloud) and Yahoo
Use your email address and an app-specific password — not your normal password. BlindBox shows step-by-step links for creating one in your Apple or Yahoo account.
ProtonMail
Requires Proton Mail Bridge, which provides IMAP access to Proton accounts.
Other (any IMAP account)
Enter your address and choose Look up settings. If the server is not found, open Advanced and enter the IMAP and SMTP details from your provider.
After you sign in
Add another mailbox
Open the menu, expand your mailboxes and choose Add mailbox, or use Settings, Account, Connected Inboxes. On the Basic plan you can connect one mailbox; Insight and Insight Plus allow more.
Choose where the app opens
Settings, Account, Default Mailbox: a specific inbox, or All inboxes. You can also reorder and remove connected inboxes there.
Connect a calendar
Settings, Account, Calendar: choose Apple (iCloud, with an app-specific password), Google or Outlook, then pick the calendar that accepted invitations go into.
Subscribe
Settings, Payments. Plans are bought through the App Store or Google Play; a plan bought on the website or desktop is managed from the web billing page.
Next, the features guide covers the mailbox, messages, All Files and Settings.

Block Mode and Voice Mode
Two alternative ways to use your mail on the phone. Block Mode turns the mailbox into large tiles with one action each. Voice Mode lets you handle mail by talking in ordinary sentences.
In this part you will learn
- What Block Mode is and how to use its tiles
- What Voice Mode can do and how it keeps you in control
- What is sent when you use Voice Mode
Block Mode
Block Mode replaces the mailbox with big, clearly labeled tiles, and moves your screen reader to the right place as you go. Turn it on with the Block Mode switch in the menu, or in Settings, Layout. Its own pages cover settings, the guide, search, files, attachments, labels and more actions.
Reading
Read or pause reading, Read thread, Email details, Attachments, Next email and Previous email.
Responding
Reply, Reply all, Forward and Compose.
Finding
Search, Folder (cycles through your folders), Gmail category, All Files, and Refresh & back to most recent email.
Acting
A Quick action tile you choose (delete, spam, archive, read or unread, star, or labels), More actions, and Prioritize later.
Getting around
Settings, Guide, and Mailbox when you have more than one account.
Voice Mode (beta)
A full-screen, hands-free mailbox. Open Voice Mode from the menu, or turn it on in Settings, Accessibility, then just talk. It has its own settings and guide.
- You speakIn an ordinary sentence
- BlindBox understandsTurns it into one clear action
- You confirmOnly for sending, deleting and other big changes
- Your phone does itAnd tells you what happened
Read and move
Read the current email, go to the next or previous one, repeat, or stop.
Find
Search your mail, open folders, ask who sent a message, or ask about its attachments.
Summarize
Get a summary of a message or an attachment.
Reply and send
Dictate a reply or a new message, hear it back, and send it.
Invitations
Hear and accept meeting invitations.
Stay in control
Deleting, sending and other big changes need a spoken confirmation, and you can say “undo”.
What Voice Mode sends
Voice Mode is off until you turn it on, and the first time it asks for your consent on a screen called “Before Voice Mode can listen”. If that notice changes, it asks again.
To understand you, each request sends your recording, its transcript, and the context it needs (such as the message you are on or the draft you are writing) to BlindBox, which uses Groq to transcribe and interpret it. If Groq is unavailable or busy, Google Gemini is used once as a backup. Each request uses one AI read, and the actions themselves run on your phone.

Mobile accessibility
BlindBox on the phone is built around VoiceOver and TalkBack, with settings for privacy, speech, touch and low vision that all work together.
In this part you will learn
- How Blind Sight keeps your screen private
- Screen reader, read aloud, sound and haptics
- Settings for low vision
Accessibility tools

- Turn it on in Settings, Accessibility, Blind Sight.
- Choose whether to show a Blind Sight button so you can switch quickly.
Screen reader support
Built and tested around VoiceOver and TalkBack.
- Each sign-in step and major change is announced.
- In key places, such as entering Block Mode or opening the composer, BlindBox moves your screen reader to the right spot for you.

Sound and haptics
Sounds and vibrations confirm what happened, with individual cues you can switch on or off.
Low vision

- Larger controls, stronger borders and reduced transparency.
- Edit the colors of all six schemes.
Less motion, less effort
Settings that cut out movement and taps.
- Reduce motion calms transitions.
- Fast actions, swipe between messages and a Delete button on each email shorten common tasks.
- Prefer plain text when formatted mail is cluttered.
Your language
Choose from 18 languages on the Welcome screen or in Settings, Accessibility. Arabic and Hebrew lay out right to left.
