A clearer picture of your Instagram connections.

UNF is an Instagram follower tracker and profile analytics app for iPhone. It records what Instagram publishes about a profile roughly once a day and builds a dated report from those checks. It also reads the Instagram data export you download yourself, which is what makes connection lists — mutuals, people who do not follow you back, new followers — possible. UNF never asks for your Instagram password.

It uses two sources, neither of which needs a login. The first is what Instagram already publishes about a username: display name, profile photo, biography, follower, following and post counts, and whether the account is public or private. The second is the data export Instagram gives you about your own account, which you download from Instagram and hand to UNF. UNF never signs in to Instagram as you and cannot act on your account.

A daily follower count with the time it was read. Following count, post count and the net change since the previous check, with Pro. Connection sections built from your export: mutuals, accounts you follow that do not follow you back, new followers and accounts no longer in your followers, once two exports exist to compare. Daily change history for public profiles you choose to track. And Profile Check, which gives grounded feedback on your own biography and the posts you select.

Who viewed your profile, who viewed your story, who unfollowed you from a single snapshot, anything from a private account you do not own, and anything in real time. None of these can be produced from public information or a standard data export. UNF leaves those sections empty and says why rather than filling them with a guess.

Request a download of your information from Instagram and add the file to UNF. That records who followed you at that moment. Later, request a second download and add that one too. UNF compares the two and lists the accounts present in the first and absent from the second. That comparison is the only method that names an actual account, and it works without giving any app your Instagram login.

No, and no app can. Instagram does not send a notification or publish an event when someone unfollows you. What is possible is comparing two lists taken at different times, which tells you that somebody left between those two moments — not when, and not why. UNF reports it that way.

Usually by asking for your Instagram username and password, signing in as you, and pulling your follower list on a schedule. That gives them a comparison basis, and it also gives them your credentials and a login on your account. UNF gets the same comparison from an export you download yourself, which is slower and needs a deliberate action from you — and asks for nothing that could compromise your account.

Accounts you follow that do not follow you back. UNF works them out by comparing your following list against your followers list, both taken from your own Instagram data export. This one needs only a single export, so it works as soon as you add your first file.

Your follower count, following count and post count, each recorded with the exact moment it was read, plus the net change between one check and the next and the history those checks build up over time. The follower count is free. The rest is included with Pro.

Yes, if they are public. Add a profile to Track and UNF notes what changed between daily checks: biography, profile photo, follower, following and post counts, and new public posts, with a before-and-after for each change. One preview is free and Pro covers up to 10 profiles.

In Instagram, open your profile, go to the settings menu and find the account centre, then "Your information and permissions", then "Download your information". Request a download of your own account, choose JSON as the format, and Instagram will email you a link when the file is ready. Add that file in UNF.

No. An export is a snapshot of one moment. It never updates itself, and no subscription, timer or AI feature turns it into a live feed. Adding a newer export is what refreshes the comparison.

UNF never asks for your Instagram password, has no Instagram login screen, and cannot sign in as you. That removes the single largest risk in this category of app. What it does collect — a generated account identifier, the username you select, dated public values, and any export you choose to add — is listed in full in the privacy policy.

Only if you turn it on. Crash reporting and screen-level usage events are off by default and stay off until you enable "Share anonymous usage data" in Settings. They never include your username, biography, follower identities or the contents of your export.

Open Settings in the app and choose to delete your account. It removes your profile selections, dated observations, imported files, generated reports and stored identifiers. It cannot be undone, and it does not cancel an Apple subscription — cancel that separately in the App Store.

There is a free tier and it is genuinely useful: a daily public-profile check, your follower count, one tracked-profile preview and the Fancy Text tools. UNF Pro costs $4.99 per month or $29.99 per year and adds the rest.

No, and this matters more than it sounds. A subscription grants access to features. It never creates data that Instagram does not publish and that you have not provided. If a section is empty because there is no source for it, Pro leaves it empty too.
