This one is one of the least obnoxious with add
Using it to unzip .7z files for emulators, and the best thing I loved about this app is, to extract the file, all I have to do is go to downloads and tap on the downloaded file and it directly opens this app and asks if you want to extract it. All the other apps needed me to open them first and navigate the files through their file browser and with every tap they would show an unskippable ad or alternate, I had to go to the file via the apple default file browser and then share the file and select their app like winzip and then it would open the app and then again select the app from their file browser yada yada yada, you get the point. Other apps had too many taps and frankly toooooo many ads, this app does have ads but so far I have extracted 3 .iso files and seen only 1 ad. And extracting is very fast as all I have to do is TAP ONLY TWICE. First on the download and the second in their app on a dialogue box asking if you want to extract.
