Dad is true Smalltalk believer, used to use visual age, instantiations etc but is a happy user of pharo nowadays which is free, opensource and under active development so could give that one a try.
I first clicked the enter button and, for once thanks to, slow loading I saw the 15 30 etc options...
So went back and clicked 15 and waited and waited not realizing I needed to press enter. So I'd change that to 15 / 20 / 30 / timeless options and no enter option...
Also after being in the experience for a few second probably I was wondering if the timer was actually running... So maybe show the timer for a few seconds (1500, 1459, 1458,1457 fade...)
Also there was no sound when I entered and then when I clicked the button I got the same text as the hackernews description and it was slightly off and unexpected (slightly off probably being a Firefox + android combo) but yeah would appreciate 2 buttons one settings, one information about or alternatively only show it once and afterwards just the panel).
Also tried to install it as an app as I'd love to have it full screen but kept the bar...
Overall it's brilliant and I'm grateful that you went the ai route and launched.
If you wanted to turn it into a paid project you could go the pixel route and offer this version for free and then the option for a one off payment to add different background, fish representations etc... He made enough money to buy a Mac to make a version for iOS as well and seemingly makes a living off it (oc in argentina, probably not possible in a HCOL lpcation.
Anyway thank you so much and hope there is some useful info here.
I'm using an extension that does exactly that¹, actually every update of the extension is mostly about then supporting more websites and asking permission to access those.
So maybe more developers could do a all sites and manually select sites option?
The extension can declare which websites it can access, but the other commenter was looking for the ability for the user to declare which websites it can access.
I just use the stock Pixel Thermometer app (actually not even sure if it's stock or you have to install it from Play Store). Some developers online have complained that there is no public API for it, which may explain lack of other apps. I have never used it for its health purpose. I only use it for objects like walls and cooking pans.
4. Unknowns Information / opensource / perfect documentation scarcity?
Something that is definitely no longer protected by patents but the original inventor / copycats haven't documented how to build it step by step and/ or insufficiently (possibly even for themselves?) and it is inherently complex?
You do understand everything is continuously sucked up everywhere right ? (I mean the pentagon mysteriously unaccounted billions have to go somewhere...)
It's not about copy the best, it's about reducing friction for someone coming from a competing product.
Hence why everyone uses the same play, stop etc "buttons" / signs on "mediaplayers" whether virtual or real. [1]
Unless your user really trusts you / doesn't have an alternative reducing friction is better than being subjectively better [2]
[1] triangle, square etc...
[2] bottom placement versus top placement of browserbar on mobile phones... From an ergonomics perspective way better but from a UX experience worse... Hence chrome changed top to bottom but was forced to change it back on android, while apple forced their users from top to bottom and didn't have to move it back
