Mike Fikes writes about ClojureScript tooling, including the Planck, Replete, and Ambly REPLs for desktop, iOS, and mobile devices.
Commenters link it for running ClojureScript REPLs on phones and for scripting with Planck, with its author answering questions in threads.
No. ClojureScript works with React Native, and in that case you can use the Figwheel REPL. See http://cljsrn.org
Ambly can be useful in other situations where you are not building a React Native app, but still want ClojureScript driving things. For an example with Ejecta, see http://blog.fikesfarm.com/posts/2017-04-29-clojurescript-ejecta.html
There are a few solutions for scripting with Clojure

Personally I wouldn't script in Clojure. If something is simple enough to be a script I'd use bash or Python and leave Clojure for writing non-trivial programs for which startup time is not an issue
Even after finishing the readme I'm not clear on what exactly this does. At the very least it looks useful for working around the macros problem[1]. Mind explaining what mileage you got out of it?

ClojureScript is these days selfhosting. If you want to write and run small scripts you could give Planck a try (ClojureScript REPL). The startup time is much smaller.

It gives you a CLJS REPL on the phone: http://blog.fikesfarm.com/posts/2015-03-05-ambly-app-bootstrapping.html Live editing code directly on the device is rather badass.
