Meh

It’s probably by design, but it’s very difficult to get the same UX on both the phone and the MacBook. For example, can’t paste in a screenshot from the MacBook into the Mac app for Dust (an iPhone app that can be installed on Mac)

History (up to 24 hours) is tight enough, but this app is most definitely more friendly on the phone.

My issue may be unique, but I control my phone through my MacBook for most of daylight.

Won’t presume to make any suggestions, but this is a bit of a thing for me.

Contradictory Data Collection vs Privacy Policy

I tend to read privacy policies. Originally, I was excited to find another app that doesn't collect data. Then, I saw that the policy you end up having to agree to certainly doesn't reflect that. To the developers - please clarify. To the app users - please use with caution.

Amazing

Beautiful app, does exactly as it’s intended, I don’t understand the hate against this app. Dust is simple and extremely effective at doing the one thing WhatsApp can’t. Message feasibly

Better than Signal

I found this app to be a better option than Signal because the messages automatically disappear in 24 hours you don't need to use your name and it's very simple to use.

Done with this app, crippled by message length max

I’ve used this app for years. And while it’s always had a pretty ugly interface and not great UI and it hasn’t kept up with modern functionality or seemed to even make an attempt at that, I did like that I trusted it and it felt secure.

What seems to show an almost willful abhorrence or unfathomable negligence for users is the fact they have weirdly capped the message length at a very short amount. Worse, is that if you are doing voice dictation, it allows you to keep talking and shows the words that you’re typing and it seems like everything is fine and then it’s not until you stop talking and go to hit send that it deletes however much of your message is over and above the maximum. If you were trying to generate customer anger and rage clicks and taps and just create an overall frustrating experience, this would be one of the top ways that I could imagine.

It’s enough for me to stop using the app after years of use. I would assume that it had been abandoned from a development standpoint, and perhaps Apple had made a change that they simply hadn’t kept up with, but I’m seeing an update from a month ago. I’m at a loss on this.
