#Accessibility of Acaia iPhone apps and scales

Hello,
I currently use the Smart Chef kitchen scale from Reflex for making coffee as well as with my espresso machine. The app’s accessible and everything, but the spoken announcement of the measurement as you pour is on the laggy side. Therefore, I’m in search of a more responsive and accessible alternative.
#Acaia has a series of coffee/espresso scales that are on the higher end of Smart coffee scales. The Pearl S scale apparently speaks the measurement and time as you pour independently of an app. If I had my choice, I’d probably opt for this one straight away. Unfortunately though, it won’t fit in between the legs of my espresso machine (Cafelat Robot). They also have two other scales. The Lunar scale that has the same dimensions of the Smart Chef scale as well as the Pyxis scale which is super tiny, but will fit. These unfortunately do not have voice prompts like the Pearl and are dependan on an app as a blind user.
Does anyone here use any of these scales? Are the Acaia apps at all accessible and if so, how’s the latency with speaking the liquid as you pour? Their scales have a bunch of other features like visual graphs where you can compare different espresso shot profiles, but I’m mostly interested in being able to know the pouring info as well as the timer. I currently use a separate interval timer app as well as the Smart Chef scale app to measure out my shots and pour-overs and while that workflow is accessible enough, the lagginess of the Smart Chef scale makes pulling a precise and repeatable espresso shot harder.
I did already reach out to Acaia with this same inquiry and this is their response: “We have previously worked with visually impaired people to develop technology to assist them with coffee brewing. This work and research led to incorporating sound and voice into the new Pearl S scale we released in November 2022. In addition to the Pearl S scale, we have made some of our supplemental applications, such as Brewmaster, compatible with native text-to-voice software on iOS and most Android mobile devices.”
While this is an encouraging response, we all know “accessible” can mean different things to different people. I was hoping for some real world blind user feedback since the prices for these scales aren’t for the faint of heart.
Thanks,
