What’s your best time to post to Instagram? We all give it some thought when we post a photo.

Prime now does that work for you. Its powerful algorithm processes hundreds of thousands of data points to determine when your followers are online, their activity, their relation to you, and, ultimately, when you should be posting to Instagram.

Prime generates a personalized Prime time for you for each day of the week. It also processes alternative Prime times, so that you can post multiple times a day or whenever best suits you while still getting the most hits on your posts.

Plus, Prime allows you to schedule as many posts as you want (including the option to add a caption to them). You can also track the success of all of your past posts.

Whether you're a business trying to maximise your posts’ engagement rates, or an everyday Instagrammer sharing your favourite moments, Prime is here to ensure you give your posts the exposure that they deserve.

Love the app. Wish it would refresh on its own.


I love the app. It's great to post at peak times to help grow my business. I wish it would refresh itself once a week, instead of me having to refresh it.
I don't really understand how their numbers and times work either. I don't know if the peak times are based on when people are active on MY posts or when people are active on Instagram in general. Either way, I love it. Just wish I understood the little details.

Don’t Bother!!! 0 stars


In the first 48 hours of use I have sent 3 error emails to the apps support and received no replies. The app has hung more than 10 times. I set up 3 test posts. It did remind me to send he 1st one but hung in the middle and did not post. When I returned to the app it had lost the post. I noticed a spelling error in the second post corrected it app hung - returned 2nd post gone, closed app and came back in to two identical posts of post 2. Today when it should have sent a reminder to publish post 2 it did not. My phone and apps are all up to date. I can see no reason to download this no-working app.

Finally works and it's amazing


So it finally stopped getting stuck on the waiting screen and started showing me the times. I don't know how it calculates it but as long as I post according to the app's recommendations, I get great engagement on my photos. Just make sure to refresh the data often as it does change, often drastically.
