Phone apps (and the mobile OSs they run on) have a very limited support lifetime. What phone apps from even a decade ago still run if unmaintained? Or are even available?

No non-disposable hardware should ever depend on a phone app, lest it become equally disposable.

All my electronics and computers from the 80s and 90s run just fine today! In great part because they don't depend on anything.

Electronics from the 2020s are unlikely to be usable in the 2060s simply due to unnecessary dependencies, even if the hardware itself is totally fine. Don't buy things like that.

Reminds me of sous vide and Joule compared to competitors. Ofc, sleek nice clean small design is nice. But only to be able to use with app... Just no. I can get those features and physical controls as well. Albeit touch screen which responses to water drops on machine usually dealing with some amount of condensation near it...

Yeah, I won't touch anything that doesn't have basic controls as physical.

Phone apps eventually failing to work is incredibly frustrating. I own several overall pretty simple Android games which were delivered as APKs which don't run on modern Android. With API targets constantly changing underneath its impossible for even somewhat basic apps to stay functional after a few generations of OS.
