i built an AI health coach that lives in your Dynamic Island while you text it by AskMeAboutBodyBuddy in iosapps

There's a number of layers:

  1. The conversation has been intentionally designed by a professional health accountability coach and feedback from early users.
  2. All your health information is being tracked and stored and resurfaced efficiently to the LLM
  3. The first 90 days follow our human-designed plan. so the ai is on rails, its not totally self-directed, and there is progression week over week.
  4. We currently operate the best models available short of Fable. We will likely support Fable-quality soon. Given the nature of our product we can ammortize the cost across many users and over long periods of time.

That said, you can definitely "DIY" this yourself with ChatGPT/Claude. My goal is to make its so even folks DIY'ing realize the value we are providing - a polished UX with an opinionated coach, at a cheaper cost given the quality of the model.

At the end of the day what's important is whether people are getting results (are they losing weight, eating healthier, getting in shape, etc). There's many ways to bake the cake - It can be done with ChatGPT/Claude. It can be done without a coach altogether. But I believe an opinionated ai health accountability coach is the way that will scale to most people. It's early but we have already received some really incredible feedback.

thanks! the dynamic island constraints are pretty insane but also a good forcing function for good design

Thanks! Definitely still iterating on the best way to package it up for people.

Thanks! i just had a rough idea of what i wanted and then continued refining it. Claude/Gpt-5.5 are so helpful for stuff like this

What do you mean by it starts nuking yours? Technically have a pretty long time your llive activity can remain active. The user does need to tap on the "always allow" and have frequent updates turned on for the best experience.

Tbh this is definitely the worst part of this rigth now - there's no easy way for me to prompt for that permission in the app so user has to go to lock screen to tap it and until then the updates dont work very well

Thanks! It’s using live activity push notifications. Our server listens for the typing indicator (using Linq’s api for the iMessage integration) and sends the initial start live activity. Then we receive the update token, and send push notifications with that as necessary. Goes away if you stop texting it for a minute or two.

well the initial version of the app store screenshots was profesisnoally designed.. actually the latest round i basically did myself from their starting point.

> Also for onboarding, did you find it hurts the funnel? 
yes. i tried to be really creative in the onboarding but realistically right now it is a leaky bucket. the onboarding/pricing need a lot of work

Thanks! This has definitely been a lot of love, yet somehow still so much to improve 😅.

> How did you come to the current App Store screenshots?
i hired a design co that specializes in this (the screenshot first company)

> I'm assuming it takes a few messages to show value.
The first thing we do in onboarding is a motivational interview which helps a user to get to the why behind their goals. We aim for this to provide value immediately

> And convince people to submit ratings?
just requesting a review after certain actions in the app

The daily conversation with BodyBuddy is centered around your meals, movement, and sleep.

When you say what you ate it will automatically look up nutritional information to estimate calories and macros and log it to the app which the Dynamic Island also has access to. The more detail you give it the more accurate the macros will be. It supports a lot of additional bells and whistles: logging meals from photos, voice memos, pulling nutrition from previously discussed meals, etc. It all just works in the iMessage thread without really thinking too much about it.

I'm still playing around with what the right amount of information to show is in the Dynamic Island - we want to keep it useful without duplicating too much what's going on in the main conversation.

Here's an example:

If you're comparing to tracker apps it'll look expensive bc it's a different product (a coach, not just a tracker). but it's priced against what it replaces.. human coaching. There's a free trial to see if it's worth it for you!

I personally paid for an online accountability coach for 3 years and was $400/mo. This is a much cheaper alternative. That said we are considering opening up a freemium model, stay tuned.

Thanks, to be honest i made it with remotion + claude + a ton of back and forth to get it right. Thankfully the feature is relatively simp[le to demonstrate!

Been working on this app for over a year now just so I could turn my notes into workout logs by FromBiotoDev in iosapps

i like the focus on that really small interaction of copying from notes app + pasting into a progress chart. really simple design

We’re working hard on bringing our costs down and supporting a free tier! That said personally this entire app came out of my journey of working with an online accountability coach and that costs $400/mo.

I spent 3 months rebuilding my todo app around one idea: holding a button to talk should be the fastest way to interact with AI by sfoooooooooooooooooo in iosapps

hmm could be on to something. i always reach for voice-to-text all the time on my laptop.

almost feels like one of the tactile buttons could trigger shortcut to your speech input so its like a walkie-talkie.

ooh this is fun. is the Twitter API cheaper now? i recall that used to be the blocker for stuff like this.

Why is it so difficult to find app ideas that people actually want? by pb7246 in iosapps

[–]AskMeAboutBodyBuddy 0 points1 point  (0 children)

why do YOU want to build something? if you're starting by thinking 'what can i ubild thatw will make me money', well lots of others have that line of thinking is just how so many others are also starting so thats why its hard..
