StoreRun.app. It transforms grocery shopping from a chore into a collaborative experience ... still private beta and about 75% there but you can kick the tires for the non-sync version.
it's been awesome ... i've been using this setup for 7+ years. Obviously with other phones (former pixel 5) but the passport form factor of the pixel fold works great for one handed use and I use it folded most of the time. Unfolded is just icing on the cake.
I build webapps so there's no difference using my phone or a laptop save for app switching/multi-window speed. As for typing speed, sure it's a bit slower but it helps I program in clojure(script) so the concise and terse syntax helps.
Also, when I need to dive into developer console I use KiwiBrowser which is slower to get around compared to desktop chrome but it gets the job done.
I've been meaning to share the minimally modified APKs I use and write a blog posts.
I use a bespoke hacker software keyboard (ctrl/meta/custom keys for GNU screen and emacs) and also bespoke SSH client (fork of the original irssiconnectbot) for years.
My phone is the original Pixel Fold. You would think I use it unfolded but the passport form factor lends itself to be almost as productive folded that I use it that way most of the time. Unfolded it's just a bit better experience (bigger keys / more display real estate/ more characters per line/ etc).
I've also been meaning to write about my setup and open sourcing my tools.
Oh. Writing clojure helps due to the terseness of the language. Not sure it would be a pleasant experience writing something like Java with the 80 character line limit I try to impose on myself
