SignalKind

The SignalKind keyboard is free forever. Check your tone as you type in any app, and rewrite it there too. No subscription needed for the keyboard, ever.

Some messages take four hours to write. Some get sent in four seconds and cost you the rest of the week.

SignalKind is for the thirty seconds in between.

Paste in a message you're about to send. It tells you what will land badly and why, names the exact phrases, and offers rewrites in a tone you choose. Or paste in a message you've been sent, and get the plain reading: what it means, what's being asked of you, and whether you're actually in trouble.

Built for ADHD and autistic people. Useful for anyone who has ever stared at a message wondering how it will come across.

SEND CHECK

Names the exact words that will escalate, undermine you, or read as an accusation, and says what to do instead. Not a score. Not a verdict on you. It runs instantly on any iPhone and needs no internet connection.

REWRITE

Three versions of your message in the tone you pick — calm, direct, warm or professional — each with a line explaining what changed and why. Take one, or take none. Nothing is ever sent for you.

DECODE

For messages you've received. Answers the question you actually have: am I in trouble? Then the tone, the deadline, what's being asked, what the sender likely meant, and the phrases worth knowing. "Let's revisit this" usually means it is being shelved.

TEMPLATES

Thirty guided drafts for the messages that sit unsent for days. Asking for more time. Chasing something ignored twice. Apologising without spiralling. Saying no to extra work. Telling family you're neurodivergent. Raising something with a school, a landlord, or a neighbour. Fill in the blanks and it goes straight to Compose.

PHRASE BANK

1,900 clearer, kinder ways to say the hard things, each with the reason it matters rather than just a swap. Sorted by where you're stuck: work, parenting, relationships, school, therapeutic settings, everyday talk, writing, and disability and access.

HOLD IT UNTIL MORNING

Park a draft instead of sending it. If you rewrite the same angry message three times late at night, SignalKind offers to hold it rather than watch you send it. It comes back in the morning, when you get to decide again.

THE KEYBOARD IS FREE FOREVER

Install the SignalKind keyboard and it checks your tone as you type, in every app on your phone. Mail, Messages, Slack, anywhere there is a text field. It flags what will land badly and can rewrite it right there without switching apps.

No subscription. Not for fourteen days, not as a trial. The keyboard is free, and it stays free.

There is also a share extension for rewriting from any app's share sheet, plus widgets, Siri shortcuts and the Action Button.

NOTHING LEAVES YOUR IPHONE

No account. No sign-up. No server. Rewrites and decodes run on-device with Apple Intelligence, and Send Check runs on your phone with no model at all. Your messages are never uploaded, never stored anywhere but your device, and never used to train anything. There is nothing to leak because there is nothing collected.

FOURTEEN DAYS OF EVERYTHING

The full app, with nothing withheld and nothing counted, for two weeks. After that, pick a plan to carry on using the app itself.

The keyboard keeps working either way, and so does your history. The drafts you wrote are yours to read and copy whether you subscribe or not.

Requires Apple Intelligence for rewrites and decodes. Send Check, templates, the phrase bank and held messages work on any iPhone running iOS 18.
