I reviewed Uplet early last year when version 1.0 was released and found it to be quite nice.
In short, Uplet allows you to upload your images to Instagram directly from your Mac. To my knowledge, this is the only Mac-based app that works with Instagram.
Eltima recently released Uplet 1.3 and addressed one of the concerns mentioned in my review. They’ve added the ability to upload videos to Instagram from your Mac! Drag. Drop. Done.
Along with video uploads, the latest version also adds the ability to work with multiple accounts. This is fantastic for Mac users who might manage multiple Instagram accounts for clients, etc. A single click beats logging-out and logging-back-in all day.
Priced at $20 it’s not for everyone, but it’s definitely worth it if you upload a lot of images, work as a social media manager, or just plain hate pulling your phone out when you’re already sitting in front of your Mac.
