For your personal number · iPhone
Every call answered.
Only the right ones ring.
Ringsworth puts an AI assistant named Charlie in front of your number. Charlie picks up, finds out who’s calling and why, and decides on the spot: ring you, take a message, book a time, or show a robocaller the door.
Coming soon to TestFlight. iPhone only. You keep your number and your carrier.
On every call, Charlie decides
-
Rings you through
When it’s someone you want, your phone rings and you get a briefing first: who it is and what it’s about.
-
Takes a message
Name, reason, callback number and urgency, with a summary and the full transcript in your inbox.
-
Books a time
Charlie knows when you’re busy, offers times that work, and sends you the event to approve.
-
Stops robocallers
Most are turned away before the call is even answered, so they cost nothing and never reach you.
How it works
One number. One assistant at the door.
Your cell forwards every call to Ringsworth. Robocallers are checked before anyone picks up. Everyone else talks to Charlie for a few seconds, and Charlie routes the call the way you’ve asked.
-
Forward your number
Turn on call forwarding with your carrier’s standard code. Your number, your SIM and your texts stay exactly where they are. Ringsworth checks that forwarding is working and tells you if it ever stops.
-
Tell Charlie about your life
A setup assistant asks plain questions: who should always get through, which hours are off limits, how to treat sales calls. It writes Charlie’s instructions for you. No prompts to write.
-
Get your attention back
Your iPhone rings for the people who matter, with context. Everything else becomes a short summary you can read when you have a minute.
The iPhone app
Everything Charlie does, in your pocket.
Ringsworth is where your phone rings, where you call out from, and where you see and steer every decision Charlie makes.
An inbox that reads like a good assistant’s notes
Every call lands in one history with a plain-English summary, the full transcript and the recording. Messages that need you rise to the top. Robocalls and blocked numbers collapse into their own “Stopped” list, with one tap to say “not spam” when Charlie gets it wrong.
- Summaries, transcripts and recordings for each call
- A “Needs you” list for messages and promised callbacks
- Search across names, summaries and what was said
- Grade a call good or bad, and get suggested fixes
Watch a call from your Lock Screen
When Charlie is talking with a real person, a Live Activity shows who it is, why they’re calling and how long it’s been. Pick up, let Charlie handle it, or block, without unlocking. Open the app for the live call screen, where you can also tell Charlie what to say: “tell him I’ll call back after three.”
- Live Activity and Dynamic Island while Charlie screens
- Pick up, hand off to Charlie, or block in one tap
- Charlie can join a call you’re on, or finish it for you
Set it up by talking, not configuring
The setup assistant interviews you, then proposes changes in plain language. Nothing changes until you approve it. Every change, whether you made it, the setup assistant made it, or someone on your team did, is saved as a version with who and why, and any version can be restored.
- Ask for changes in plain English, by voice or text
- Rename your assistant and hear voice options before you choose
- See exactly what Charlie knows about you
- Version history with one-tap restore
-
Contacts and VIPs
Mark VIPs who always get through. Tell Charlie what to call someone and what to know about them, and preview exactly what happens when they call.
-
Presence that knows your day
“In a meeting,” “driving,” “on vacation.” Set it by hand or let your calendar do it, and Charlie tells callers and routes calls to match.
-
A blocklist with judgment
Block a number or a whole pattern. Robocallers Charlie catches can be blocked automatically, and you can always overrule it.
-
Rules you can test
Quiet hours, weekends, VIPs always ring, unknown callers screened. Ask “what happens if Mom calls right now?” and see the answer before it matters.
-
Room for your team
Add people as owner, admin, human assistant or viewer. A human assistant can see calls and messages without being able to change how calls are routed.
-
Your default calling app
Calls you place from Ringsworth show your own cell number, so people recognize you. Emergency numbers always go through your phone’s regular dialer.
Charlie makes calls for you
Hand off the calls you’ve been putting off.
Give Charlie a goal and a number. It places the call, gets the answer, and reports back. If it needs a decision mid-call, it pauses and asks you.
- Get something done“Call the dentist and move my cleaning to next week.”
- Call someone back“Tell Sam I got the quote and Thursday works.”
- Schedule a meeting“Find 30 minutes next week with Jordan and Priya.”
- Just ask“Ask the shop whether my order came in.”
Always honest about being an AI
Every call Charlie places starts with it saying it’s an AI assistant calling for you.
Pauses to ask you
Two times on offer, a price to confirm? Charlie asks you in the app and carries on with your answer.
Knows a voicemail when it hears one
Charlie waits for a real person before speaking. If it reaches voicemail, it hangs up and tries again later.
Your number, if you want it
Calls can show your own cell as caller ID, so people pick up for a name they know.
Meetings with one person or several
Charlie works out a time with each person and sends you a calendar event to approve.
Reliability
Your phone still rings. Even when the Wi-Fi doesn’t.
Screening is only useful if the good calls get through. Ringsworth is built so a weak connection never costs you a call you wanted.
The Home screen shows a single health badge for the whole path, from carrier forwarding to your phone. If something breaks, you see what and how to fix it.
-
Rings over the internet
Normally the app rings you over Wi-Fi or mobile data, with the briefing on screen.
-
Bad connection? It rings your cell instead
When the app wakes up for a call, it checks the connection. If it’s poor, the call goes to your phone over the regular cellular network.
-
Connection drops mid-call? It moves to your cell
The caller hears a short “one moment” while your cell rings. Answer and you’re back in the same conversation.
-
Can’t reach you at all? Nothing is lost
Charlie comes back, apologizes and takes a message, so the caller isn’t left hanging and you know they called.
Robocalls
Robots get stopped, not entertained.
The cheapest check runs first. Most robocalls are turned away before anyone answers, and Charlie only spends time on calls that pass every earlier check.
-
Before answering
Turned away at the door
Your blocklist, number reputation, spoofed caller IDs (including your own number or a fake “neighbor”), invalid numbers and sudden bursts of calls. Stopped calls never ring and cost nothing.
-
A quick check, no AI
Machines can’t say hello
A recorded message talks straight through; a person says hello and waits. Silence, fax tones and failed challenges end the call here.
-
Charlie, on a short leash
A hard time limit
If a robot or sales pitch slips through, Charlie ends the call, and can block the number automatically. Unknown callers get a capped amount of Charlie’s time.
Charlie keeps a quiet tally of what it stopped and the time that saved you.
Privacy & control
Your calls are yours. So is the off switch.
Ringsworth processes call audio and transcripts to screen your calls. You decide how long anything is kept, who on your team can see it, and when it’s gone.
Retention you set
Choose how long recordings, transcripts and robocall records are kept, separately.
Export everything
Download your calls, transcripts, recordings and contacts in one archive whenever you like.
Delete for real
Delete a single call with its transcript and recording, or delete your whole account from the app.
Roles, not shared passwords
Owner, admin, human assistant and viewer each see only what their role allows.
Calendar on your terms
Charlie sees when you’re busy, not what the meeting is, unless you choose to share titles.
Lock the app
Recordings and transcripts are sensitive. Require Face ID to open the app.
FAQ
Questions, answered by a human.
Something else on your mind? Email us.
Do I have to change my number or my carrier?
No. You keep your number, your carrier and your SIM. You turn on call forwarding with your carrier’s standard code, and calls to your number reach Charlie. You can turn forwarding off at any time.
Will the people I care about have to talk to a robot?
Every call goes to Charlie first; that’s the design. But you decide what happens next. VIPs and rules you set (family, the school, anyone during work hours) can ring you right away, and Charlie still keeps a record of the call.
What happens to my texts?
Nothing changes. Ringsworth handles calls only. Texts and iMessage stay with your carrier and the Messages app.
What if my internet connection is bad?
If your connection is poor when a call comes in, Ringsworth rings your cell over the regular cellular network instead. If your connection drops during a call, the call moves to your cell. If you can’t be reached at all, Charlie takes a message.
Does Charlie tell people it’s an AI?
Yes. Every call Charlie places for you starts with it saying it’s an AI assistant calling on your behalf. You choose how Charlie greets the people who call you.
Can I change Charlie’s name or voice?
Yes. “Charlie” is the default name. You can rename your assistant and hear voice options before picking one.
What about emergency calls?
Emergency numbers are never placed through Ringsworth. The app hands them to your iPhone’s regular dialer so they go over the cellular network.
Is there an Android app?
No. Ringsworth is an iPhone app.
