Unfollowers, admirers, mutuals, ghost followers, story viewers and the hours your audience is online. All of it read from your own account and kept on your own phone. WHAT YOU GET • Unfollowers — who stopped following you, and when. "Doesn't follow back" and "left you" are two different things, and UNFO keeps a dated history so you can tell them apart. • Admirers — people who follow you while you don't follow them back. • Mutual followers — the accounts you and they both follow. • Ghost followers — followers who never watch your stories and never react. • Story viewers — everyone who watched, most loyal first. • Recommended times — your best hours to post, worked out from when your own story viewers show up. • Follower trend — daily gains and losses, drawn as a curve. • Ghosty, your assistant — ask in plain language ("who unfollowed me this week?") and get an answer built from your own numbers. HOW IT WORKS UNFO signs you in on Instagram's own login page and reads your account the way the app does. Your lists are calculated and kept on your device. UNFO never posts, likes, comments or follows for you. It also refreshes on its own, in small steps, so your lists stay current without you pulling to refresh. PRO A subscription unlocks the full lists and the history behind them. Payment is charged to your Apple ID; it renews unless you turn off auto-renew at least 24 hours before the period ends, and you can manage or cancel it any time in your Apple ID settings. Terms: https://unfo.web.app/eula.html Privacy: https://unfo.web.app/privacy.html UNFO is an independent analytics app. It is not affiliated with, endorsed by or sponsored by Instagram or Meta.

Verdict

The call

The clearest difference is ads: Sharp at none against UNFO's shown. Sharp also leads on update cadence (every 3 days vs every 3 weeks) and review sentiment (50% vs 28%). UNFO's advantage is ratings volume (174 vs 3) and rating (3.3 vs 3.0). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Sharp sells 2 in-app purchases, starting at $9.99 per 7 days and UNFO sells 19 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

UNFO holds the better App Store score, 3.3 against 3.0. That said, the two scores are not equally well evidenced: UNFO has 174 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Sharp's written reviews are positive against 28% of UNFO's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sharp ships an update every 3 days, UNFO every 3 weeks. The most recent releases landed on October 8, 2026 and October 20, 2026 respectively.
