What’s your best time to post to Instagram and Twitter? Posting at the right time can organically increase your likes + traffic by over 90%!

Prime does that work for you! Our patent pending algorithm checks hundreds of thousands of data points to determine when your followers are online, their activity, their relation to you, and, above all, WHEN you should be posting to Instagram or Twitter, for each DAY of the week and each TIME of the day (yep, you can plan multiple posts a day!).

Plus, Prime allows you to schedule as many posts as you want with bonus features like preset hashtag sets and automatic prime time posting. On top of that, you can preview your grid (with premium Grid Preview) so you can see how your Instagram grid will look ahead of time!

You can also track the success of all of your past posts and supercharge your Instagram game by reposting your most popular posts.

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

Happy Priming!

What’s New

Version 5.1.1

Hey Primers!

We've been working VERY hard recently, and we're excited to bring you the BEST Prime yet!

We've rebuilt the Prime Time algorithm from the ground up, and it's now over 60% faster and over 45% more accurate than it used to be. That's our biggest improvement EVER. That means more likes, more comments, and more time for you.

Oh, and we're now fully iOS 15 compatible!

Check it out and let us know what you think :)

Happy Priming!

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.

Good tool

I agree with others—that having a better understanding of of the prime time is specific to me, or if it’s for everyone would be nice—but regardless, I like knowing what that’s supposed to be and follow the lead. I’m still trying to decide if I care to have notifications on—because if I don’t have a post planned, I’ve found myself scurrying to come up with something, but for now it’s nice to see.

The app doesn't work at all. I tried to log in to my account no less than 10 times. It goes through the log in channels just to throw you back to the log in page. IF and WHEN you manage to actually log in and use the app, it takes forever to refresh the account just for you to find out it wasn't actually refreshed.
In addition the app claims that the refresh will only take a minute or less. Timed over two minutes.

I paid for something I couldn't even use!
