Great app - very responsive developer

For those, like me, who have visual trouble with white text on a black background, I asked the developer if there could be a fix. He replied quickly and, in two days, provided a white background with dark text option. Bravo,

New favorite app

Really impressed. I’m amazed that I can use Loci without a subscription / completely free given how fast and performant it is. Love that my data doesn’t go anywhere. Whole experience is very polished, A++

Very happy I tried this app

This app was super user friendly and practical. I travel a lot during the day where I intermittently lose service - this allows me to stay connected.
