Some accounts are just a little sus.
Maybe your crush suddenly started following a bunch of new people. Maybe an ex keeps popping up in someone's activity. Maybe you just like knowing what's going on. Whatever brought you here, Sus turns public Instagram activity into something you can actually read at a glance.
WHAT SUS SHOWS YOU
Pick a public Instagram username. Sus pulls that profile's publicly visible information and lays it out clearly:
- Their most recent follows, newest first, with timestamps
- Who recently started following them
- Follower and following counts, plus how those numbers move over time
- A quick breakdown of how many of their newest follows read as guys vs girls
- A playful Sus Level meter, from Very Safe all the way to Super Sus
HOW IT WORKS
1. Type in a public @username. No Instagram password. No login. Nothing to connect.
2. Sus reads what that profile shows the world and builds your first report in seconds.
3. From then on, the profile is re-checked every hour in the background.
4. When something moves, a push notification lands on your phone.
THE WHAT'S NEW FEED
Every change across every profile you follow lands in one scrolling feed. New follow, unfollow, new follower, count jump, username change, account went private — it's all timestamped and marked NEW until you've seen it. Open the app once a day and you're caught up.
NOTIFICATIONS, YOUR WAY
Three separate switches in Settings: new follows, new followers, and count changes. Turn on what you care about, mute the rest, change your mind whenever.
TRACK UP TO FIVE
Five profile slots. Swap any of them out whenever you want — removing a profile clears its history for good.
WHAT SUS DOES NOT DO
We want to be straight with you, because a lot of apps in this space aren't:
- Sus only reads PUBLIC profiles. Private accounts cannot be tracked, and we will tell you so instead of pretending otherwise.
- Sus never asks for your Instagram password, and never asks for theirs.
- Sus cannot show messages, stories, hidden followers, or anything an account keeps private. If you can't see it on a public profile, neither can we.
- Sus is not a background listener, a location tool, or a way into someone's account. It reads what is already public, on a schedule.
BUILT TO BE EASY ON YOUR EYES
Near-black backgrounds, electric lime accents, big readable numbers, no clutter. Sign in once with Apple or Google and you're in. Available in English, French, Spanish, Portuguese, Japanese and Romanian.
SUBSCRIPTION
Sus is free to download. Full tracking, hourly checks and push alerts are unlocked with a weekly, monthly or yearly subscription. Cancel any time from your Play Store account — no phone calls, no retention maze. You can delete your account and every piece of data tied to it from inside Settings.
