UnfollowCheck checks who follows you on Instagram every week. The moment someone leaves, you get a push notification with their @username — plus a running list of every person who doesn't follow you back.

We never ask for your password.
Every other app does.
Instagram trackers have a bad reputation for a reason: most require your login and get accounts banned, hacked, or shadowbanned. UnfollowCheck uses Instagram's public data — so there's nothing to risk.
