Me hackearon después de instalarlo

No sé si sea una coincidencia bien coincidencia pero después de instalarlo para ocupar autosbcs en safari la misma noche me sacaron plata de mi banco, primera vez que me hackean el banco

App is terrible

Arguably such a garbage app that deserves no wasted time.
Deserves to go into a dumpster. Thats how garbage this app is.
Just stop making garbage apps like this.

Amazing

Open source, no frills, free. Works great. Not all scripts work but I think that is just a limit of iOS. But overall it works great.

Doesn't work

Doesn't work on IOS, I activated it in safari and gave it permissions, i tried multiple scripts, none of them did anything, i tried force restart safari. There is no guide for IOS, only for macos, out of ideas.
Uninstalled it, bye.

Weirdly few reviews for one of the greatest safari extensions

Safari has far less extensions than Chrome or even Firefox. Userscripts are browser agnostic. This is the best userscript application. This is FOSS. How hard can a piece of software deserve 5 stars? This software deserves 6 stars. It’s sort of sad that userscripts aren’t more popular.
