The real question is why do toothbrushes need apps in the first place?

To collect as much customer data as possible, to (hopefully) anonymize it and bundle it to sell them to data brokers and extract more money from their customer base... All of it with their "consent" (you installed the app and likely accepted their ToS/PIvacy Policy), under the pretense of providing them a service like counting the time/frequency of your interaction with the product or reminding you to use it (somethi…

My question is: why do an Oral-B app and a Colgate app even exist?

The app can tell you which teeth are correctly cleaned (i.e. you spend enough time on it) and which teeth you forgot or went too fast. Personally I just used it once and ended up removing it, but I can see some people using it to ensure their brushing is efficient. Anyway, it's completely optional, you can just use the brush ignoring the existence of the app.

That’s actually kind of cool. That’s exactly the sort of feedback that gets me to do things correctly. Detailed feedback has enabled me to consistently work out, wake up early and eat healthy. They’ve helped me keep those good habits going for 4 years now. I’m the kind of guy these apps are built for.

Eh, I disagree. High res images are big no matter what way you cut it, and my mobile resolution is 2550x1800 - I don’t mind the detail. But I don’t need that detail for 15 different toothbrush models.

A 3840x2160 jpeg image at 100% quality is somewhere between 2 and 3 MB, so 15 models makes 45 MB, still way short of + 300 MB for the app.

JPEG at 100% quality makes very little sense - the goal is to dial it down to the lowest value where artifacts are still low enough to not notice. AVIF also has much better behavior in the artifact department, letting you go much lower without introducing artifacts - you simply loose detail, which is no issue in a largely smooth product photo.

For reference, my own photos downscaled to 3840x2560 AVIF for sharing purposes range from 500KB to 2MB depending on how "busy" the image is. The off-camera 6000x4000 JPEG is ~7MB in comparison.

I stand by my opinion that a few hundred KB per image is plenty at the required resolution for model photos in an app.

I know this is probably going to land with a thud in this venue, but as a counterpoint to the predictable "why do toothbrushes need an app?!", it should at least be acknowledged that these apps might be the first and only place someone could learn of good oral hygiene.

Weird, I learned this in three places, at kindergarten, again in school, and at home

And that's good! But it can't be assumed that everyone had the benefit of that experience.

So only twice the size of your JPEG example. Looking at the area chart of the files, it looks like the majority of the assets are less than that 2-3MB.

There's probably over 200 or so assets in that 233MB archive.

More embarrassing than the size itself is that it is supposedly required to change the mode of the toothbrush. I truly do not think this should be allowed, but I’m not sure how to approach enforcing it.

On my IO, you can change the mode from the toothbrush, but the selection of modes to change from is on the app. However, I think it defaults to "all of them" so it's still usable without ever running the app.
