4k Stogramis a Mac utility that provides you with a simple way to back up your Instagram photos and videos. The program features a user-friendly interface, comes with an integrated search tool that provides you with accurate results, and is available in various languages.
All you need to do in order to use this tool is to enter a keyword, Instagram account or a hashtag (for example, "#labrador"), and the program will immediately provide you with the results you need. You can preview the found pictures and videos while the utility downloads them to your local directories.
Sadly, 4k Stogram doesn't bring you the option to choose which of the found images and videos to be downloaded to your Mac. Instead, it automatically downloads all of the items from the results window.
Another thing that bothers me about this tool is that it occasionally freezes, especially when switching between its windows. Also, even though it's advertised on its homepage that the product is free, it actually isn't. You need to pay in order to download as much content as you need, to install the tool on more than 3 computers, etc.
So, it's up to you to decide if it's worth buying this program for your Mac or not.
