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.

Never got to use the app ### 1/5 — Buggy *2024-11-27, version 5.1.1* Can’t even write a proper review for this because I can’t get it to log into my Instagram. Just get sent in circles back to the log in page… ### 1/5 — Does not work *2024-11-22, version 5.1.1* Downloaded. Over 22 tries to log in to my account and it keeps bouncing back to the login page. Is this normal????? ### 1/5 — How are you still operating? *2024-10-22, version 5.1.1* All the reviews from a year ago with log in problems, it’s still exactly the same. ### 1/5 — not connecting *2024-07-16, version 5.1.1* no matter how long i wait or how many times i delete and retry, it won’t connect to my insta page. gets caught in a loop of collecting data. but on that page it says it “shouldn’t take more than 60 seconds” .. how about two days and still nothing? 😒 ### 1/5 — Can’t seem to get logged on *2024-07-04, version 5.1.1* Downloaded app, entered all details and it said it takes 60 seconds and don’t close. So I’m sat there trying to keep the screen from sleeping for over 10minutes. Tried it multiple times and it doesn’t work. ### 1/5 — Did not do anything but take my details. *2024-06-21, version 5.1.1* It said it would take no longer than 60 seconds but it’s been five minutes with flawless Wi-Fi and still nothing. I’m hesitant to believe people got results. ### 1/5 — Worst App Ever *2024-05-15, version 5.1.1* I let it calibrate for over an hour, even though the app says less than a minute. It never logs in. Nothing happens. ### 1/5 — Doesn’t work stuck in calibrating *2024-05-04, version 5.1.1* Doesn’t work stuck in calibrating. I was really hoping smh. ### 1/5 — This app doesn’t work *2024-03-27, version 5.1.1* There’s something wrong with this. It never logs in. It asked you to log into IG or FB and then it spins and spins. Never completes the login. ## Frequently asked questions about Prime ### What does this app do?
