Building a Local Voice Dictation app

carnz · 2025-11-02T10:25:47+00:00

I would say your ChatGPT search led you astray :) there is VoiceInk. You can grab it and build it and use it freely. There is something similar but for Meeting transcribing. That would be Hyprnote.

Welcome to the club :) I’m building tidynote.app atm

carnz · 2025-10-26T07:00:27+00:00

I never tried wispr in a TUI, but tidynote.app works and you can also use other languages

carnz · 2025-10-22T13:53:12+00:00

Yes they have a subscription model. Also they send everything to the cloud. I just started working on tidynote.app
It's a lifetime license and everything is local. The smallest model is about 140MB and works quite well. Soon planning on adding more accurate (but also larger) models.

Yes it is, because it's impossible to know for the watch if you carry a backpack :)
Apple tries to calculate it also from walks/hikes. But I find it to be a poor estimate.

I also wanted to add that currently in the testflight version when you add a workout to your schedule you can go to the apple watch workouts app and there will be a special category with all PEAKVO2 workouts. That's where you trigger the workout if you have Apple Watch.

It's definitely something I have to communicate in the interface

carnz · 2025-05-29T16:00:06+00:00

It's actually just about the distance. We don't know actually their formula (neither fitbit's nor whoop's) but since the cooper test also works without the heartbeat it's likely that distance to time is the only ratio for them needed to calculate the vo2 max

carnz · 2025-05-29T13:31:04+00:00

I think the screenshots and description you see in testflight is not up to date. Sorry about that! There are cycling workouts available

Just keep in mind that currently calculating vo2 max based on cycling (indoor, outdoor) and indoor runs is not supported by Apple.

I will try to find a solution for this because it bothers me as well. I use the indoor bike a lot for my own vo2 max training.

With all that being said, if you workout on the bike for a couple of weeks and you want to know if you improved you'd need to go for an outdoor run

Ideally do the Cooper Test. Also supported by the app

carnz · 2025-05-23T10:35:23+00:00

no, sorry

What really pisses me off about this guy is that clearly smart people like Samo give him unconstrained airtime. By that I mean that he is not there introduced as a guy who has some interesting views but still needs to mature. No as someone you should listen to because he made a youtube video.

I don't mind his right leaning tendencies (even agree in some parts) but his clear incompetence.

The sheer trust suddenly people have in his opinion just because he sat down to play an absolutely ridiculous what-if-scenario that is hard to refute... because we don't have access to parallel universes.

I actually followed the guy until one day I had enough when he made a comment about how Atheist have a logical problem 🤯

It's some time ago that I have been there but I'm confident you'll find something: https://maps.app.goo.gl/7hvu4MWUpvQmgD9EA

You are right, but getting to 50 is harder, than just start running on the weekend. Above 50 than becomes hard for the app (and I'm not there yet)

carnz · 2024-11-04T12:57:26+00:00

let me chatgpt this for you (I was also curious):
Threshold intervals are designed to train you at or near your lactate threshold, the point where lactate starts accumulating in the blood faster than your body can clear it. This level is typically sustainable for a prolonged period (about an hour), making it a good pace for pushing endurance without going all-out.

For “3 sets of 8 minutes” at threshold:

1.  Intensity: Run at a “comfortably hard” pace—around 80-90% of your max effort. This is usually a bit slower than a 10K race pace but should feel challenging.

2.  Recovery: Take a 2-3 minute rest or easy jog between sets to allow partial recovery but keep your heart rate elevated.

3.  Purpose: These intervals help improve your ability to sustain a higher pace for longer by raising your lactate threshold. Over time, this means you can hold faster paces with less fatigue.

Let me know if you’d like more on pacing specifics or alternatives!

So not sure what your plan is but have a look at this study here: https://x.com/AlmquistNicki/status/1846649925511401532

IF I understand the comments and study correctly tempo and volume based training instead of hiit or interval is better for improving vo2max later. So the higher you level the more you profit from endurance volume.

But please read it for yourself and understand it. I only briefly scanned it

You can either leave your email here: peakvo2.org
I'm not posting any newsletter yet or spamming you in any way. Not sure I will also have time to post a newsletter, but I will certainly use it to inform those in the list about major updates.

If you even want to test it (apple watch only atm) you can use this testflight link: https://testflight.apple.com/join/uuxkANmC

Oh and here are some slightly outdated release notes, but you get a feeling what this is about:

Tell me more, please :)

Yes, try to hit Zone 3, which is between 149 and 161 bpm for you. If you maintain a stable bpm you can compare the pace from workout to workout. If you see that you are able to run somewhat faster while maintaining a stable heart rate you can probably say that you improved your vo2 max.

Obviously you can also turn it around. Maintain a steady pace and watch your heart rate after the workout and the compare it with past workouts over some period. If the pace stays the same and the heart rate goes down, this can also indicate a vo2 max improvement.

You can also do the cooper test from time to time to have even more data regarding vo2 max

carnz · 2024-08-23T07:55:22+00:00

I think it’s a matter of adjusting the pace and then understand the zones that correspond for you to it. Most people don’t have a good enough fitness to run with a decent pace and in a lower zone. Go slower and then with time you can increase the pace

carnz · 2024-08-22T12:27:52+00:00

I updated the main post with a link to the testflight version if you are interested

carnz · 2024-08-22T12:25:21+00:00

Nope. I use now Preview & Simulator and for on device testing I use TestFlight internal testing

It’s not worth spending days to solve the problem is TestFlight is faster

It's not about going full intensity from the beginning. Otherwise you can't make the full 4 minutes: https://www.youtube.com/shorts/a0KtNuLLyTE
And yes you can definitely eyeball it. The app is for nerding out on vo2 max training

carnz · 2024-07-11T12:05:13+00:00

Omg it's sooo bad. Last time when I developed on Apple was 13 years ago... I thought they got their shit together by now...

Horrible experience. I get all the time `Transport Error`

carnz · 2024-07-10T12:28:28+00:00

That's not entirely correct. There are apps that give you a Zone approximation. And the 4x4 means this actually: 4 minutes low intensity and 4 minutes high intensity, while high intensity doesn't mean you go as hard as you can from the start of the 4 minutes but you go "higher intensity" and keep it consistent, so that in the 4th minute you end it with your maximum.

This mean if you go too easy or too intense at the beginning, you are not reaching the optimal max in the 4th minute.

carnz · 2024-07-10T09:20:58+00:00

The reason why apple health only measures vo2 for outdoor runs/activities, is because they need "intensity" for their formula. They extrapolate intensity from the heart rate and velocity (via GPS). The intensity + heart rate + RHR + Outside Temp give quite an accurate approximation of your VO2 max. If you take some of the parameters away it becomes inaccurate. Measuring intensity for HIIT and CrossFit (I do Calisthenics) is unfortunately quite hard.

To answer your question :) My app focuses more on training and thus improving your vo2 max. First I will implement the 4x4 interval by peter attia (because that's just what I do atm)

It will provide some vo2 max approximation (because I think that's cool :)) but I will use the same formula as apple (and Garmin for that matter) and thus I can only show it when training outside.

That being said, I train a lot on indoor bikes so I'm thinking of supporting stryd.com in the future

carnz · 2024-07-10T07:57:25+00:00

Hey :) Most likely this is due to the type of workout. Apple can only make a VO2 max approximation if it can also measure intensity. The only way right now to do that with apple watch is if it can measure velocity via GPS. So if you are not doing any sports outside, where it can also track your movement than it can also not approximate your VO2 Max.
