Neutrino+ is a free Instagram promotion app for Android and iPhone. Users help each other: you like, follow and watch for other users, earn crystals, and spend them on real followers, likes, comments and views for any account.
Users do small tasks for one another: a like, a follow, a comment, a Story view. Every action comes from a real person on a real account, so what you receive is genuine engagement, not bot numbers.
Each task you complete pays crystals. Spend them on followers, likes, comments and views for your own profile or any other account. The app is free to download and free to use. If you want to grow faster, you can also buy crystals in the app, but you never have to.
Neutrino+ is not on Google Play or the App Store. Android gets a signed APK, iPhone gets a TestFlight build, and this website is the official source for both.
The whole process takes a few minutes the first time and runs in the background after that.
Get the Android APK from the download page or join the TestFlight build on iPhone.
Sign in through the built-in browser; your password never reaches us. We recommend a second account for earning crystals (how login works).
Like, follow, comment and watch stories for other users, manually or automatically with AutoBot.
Spend crystals on any Instagram account or post, including accounts you are not logged into.
Always download from this site or the official download page. Copies hosted elsewhere may be modified.
Tap Download; the download page gives you the current APK file.
Open the file from the notification or the Downloads folder. If Android asks, allow installing apps from this source; it is a one-time permission.
Log in with Instagram inside the app and the Earning tab is ready: tasks, Daily Bonus and AutoBot are all there. We recommend a second account for earning (see the login guide).
To update, download the new APK and install it over the existing app. Your crystals and settings are kept.
Get Apple's TestFlight app from the App Store if you do not have it.
Tap Download on this page and accept the TestFlight invitation.
Install Neutrino+ from TestFlight and open it from your home screen.
TestFlight builds expire periodically. If the app stops opening, return to this page and install the current build.
Earning comes first. Crystals are the app's currency, and you collect them by doing for other users exactly what you want done for you:
Each task pays a fixed number of crystals. AutoBot can run these tasks for you in the background. You can also claim a daily bonus by opening the app, and invite friends through the affiliate program.
When you have enough crystals, open a post and increase its likes, views or comments: choose the amount and confirm. Orders are usually delivered within minutes to a few hours depending on the size.
AutoBot is the part of Neutrino+ that earns while you are away. It automates your own account's tasks; the users who like and follow you in return are still real people. If you were looking for an Instagram auto liker: AutoBot earns the crystals, and the likes for your posts you order with them. Read the AutoBot guide.
Choose how many actions AutoBot may perform and how fast. The limits apply per account, so a spare account can work harder than your main one.
For every account in Multi-account you decide separately what AutoBot is allowed to do: likes, follows, comments or views, in any combination.
AutoBot runs on up to three accounts at the same time, each with its own task set. More accounts, more crystals, one balance to spend.
Spending crystals is the easy part. Open a post, choose what it should get, confirm, and real people deliver it.
Generated emoji sets, generated text comments, or lines you type yourself; comment orders go to real people who post them under your photo.
Order 1,000 or 5,000 Reels views, Story views or video views the same way as likes. Views are delivered by real people watching your content.
Every like and comment comes from a real account. If an order is cancelled for any reason, the crystals for the undelivered part come back to you.
Followers come from TOP, the list of accounts users follow for crystals. You buy time in that list, and users do the rest. How TOP works.
While your account is in TOP, every active user can follow it for a reward. The longer you stay and the busier the hour, the more followers you get.
Put your main profile, a friend's or a client's account into TOP straight from Bookmarks, with no login for that account.
Users who follow you from TOP are watched for 14 days. Whoever unfollows can be found and penalized, and their Energy, the app's fair-play balance, becomes your crystals.
Followers you receive through Neutrino+ are real people who chose to follow you for crystals. A few try to cheat: follow, collect the reward, unfollow. The app catches that. How unfollower detection works.
For two weeks after an order, Neutrino+ periodically re-checks that each user who followed you is still following.
Open the suspects list in your profile to see exactly which users unfollowed you and when.
Report an unfollower from the list and the app penalizes them, so cheating does not pay and your follower count stays honest.
Share your invite link. You get 500 crystals for every friend who joins, 10% of what they earn and 30% of what they buy for 60 days, paid on top of their own rewards (how the referral program works). Try the numbers:
Estimate. Actual rewards depend on the program terms in the app.
A few things the sections above did not cover. Everything is free; there is no premium tier.
Open the app daily for a bonus on top of what you earn from tasks, and watch our social networks for gift codes.
Choose a region such as Europe or Latin America so that most of the engagement comes from users near you.
Link up to 10 Instagram accounts, switch between them in one tap, and move crystals between your own accounts.
Order likes, views or followers for any Instagram account with no login for that account: save it by username, yours, a friend's or a client's, and order (how Bookmarks work).
You sign in on Instagram's own page inside the app; Neutrino+ never sees your password. No root or jailbreak needed (how login works).
The APK is light and runs on older Android phones. Updates install over the existing app and keep your crystals.
Neutrino+ is independently developed and is not affiliated with or endorsed by Instagram. Like any engagement exchange, it should be used with care.
Login happens inside the app's built-in browser; the service has no access to your credentials.
Earning involves liking and following many accounts. Doing that from a spare account keeps your main profile's activity natural; order for your main one through Bookmarks.
A sudden jump from 100 to 10,000 followers looks unnatural. Spread orders over days.
Followers and likes delivered by the app are real actions by real users and are not removed when you stop using Neutrino+.
If Instagram temporarily restricts an account used for earning, pause tasks for a day or two before continuing.

How to gain thousands of Instagram followers with Neutrino+
The three apps follow the same exchange model: earn by doing tasks for others, spend on your own account. The differences are in platforms, what you can order and how the app protects what you paid for.

Based on what each app lists on its official site as of November 2026; a dash means the feature is not listed there. See the TOP guide for how followers are delivered in Neutrino+.
Earn crystals by completing tasks for other users or by running AutoBot, then put your account into TOP. While it is there, users follow you for crystals. Likes, views, comments and saves are ordered the same way, for any post. How TOP works.
No. Every follower, like and comment comes from another user of the app on their own Instagram account. AutoBot only automates the tasks your own account does to earn crystals; it is not a fake account and it does not generate fake engagement. Read the AutoBot guide.
Users exchange engagement with each other. You earn crystals by liking, following and commenting for others, and spend crystals to receive the same for your account. It is the like4like and follow4follow principle (like for like, follow for follow), organised by the app.
