Nudge Bird
Alpha · invite only

You've quit four habit trackers. You've never ignored a ringing phone.

Nudge Bird calls once a day and asks whether you did the thing you said you'd do. Press 1 for yes, 2 for no. Nineteen seconds, then it hangs up. Nothing to keep up, and a few weeks in, your answers start showing which habits go with your better days.

One message when it opens. No phone number needed yet.

Five people have been taking this call since August. That's the entire user base, which is why you can't sign up yet, only wait.

1

Pick a few habits

Up to four, in the app. Things to do, things to avoid. Then close it.

2

Your phone rings

Every evening, at a moment you don't know in advance. A call you can predict becomes furniture in a week.

3

Press 1 or 2

Nineteen seconds, and it hangs up. Tomorrow it asks again, in the same voice, whatever happened today.

A few weeks in

Your answers start showing what goes with your better days

Every call ends with how your day was, 1 to 5. Put that next to what you did, and a few weeks in, the app can show you which habits go with your good days, which weekday is usually hardest and how fast you bounce back. After a week of answers, Monday brings a short summary.

“Go to the gym” goes with your better days

Days you went 4.0
Days you didn't 2.6
An example, as the app shows it: your own day ratings, averaged. They go together; that doesn't prove which causes which.

The call, in full

"Hi Daniel, Nudge Bird's automated assistant. Press 9 to stop."
"Did you run? Press 1 for yes, 2 for no."
1
"And how was your day? Press 1 to 5."
4
"Thanks. Talk tomorrow."

Everyone else built a chatbot with a phone number

The other apps that ring you put an AI coach on the line and hope you'll open up to it after a long day. This one asks its question and hangs up.

Lying to an app is easy. Answering is harder.

A tracker believes whatever you tell it, whenever you get round to telling it. A call arrives at the end of the day and asks while you still know the answer.

Missing a day costs you nothing

No streak to protect, no grid going grey while you're ill. Tomorrow asks the same question, in the same voice, as if nothing happened.

Straight answers

Is it AI?
The voice is. It reads lines a person wrote in advance, and the call says so before it asks you anything. Nothing else is. No model decides what to say or listens to you, and the patterns the app finds in your answers are shown to you and nobody else.
Are you recording me?
No. You answer by pressing keys, not by speaking, so there's no audio of you and nothing to transcribe. The only thing stored is which digit you pressed.
Will you sell my data?
No. There's no advertising in this, no third-party trackers on this page, and nothing is ever sold to you on a call. Ask for your data to be deleted and it goes.
Is there an app?
Yes. The calls never need it, and it's where your answers turn into something: a summary after each week you answer, and after a few weeks, which habits go with your better days. It's also where you choose what gets asked, and where you can answer on a day you missed the call.
How do I make it stop?
Press 9 during any call, or switch it off in the app. It stops that day.
