## About IdeaFast

IdeaFast (ideafast.pro) checks the problem behind a startup idea against Reddit: it finds what people keep complaining about, scores each problem 0 to 100 and links every one to its threads.

Pick the subreddits where your customers talk, and a scan groups their posts into recurring problems with real quotes, so you read what people wrote in their own words, not a summary. You can also paste a written idea and get an evidence report with a verdict, or turn a problem into startup ideas.

Pay once, no subscription. Scans never expire, and your first scan is free with no card. A free library of scored problems needs no account: https://www.ideafast.pro/explore

Made for founders and indie builders before they build: testing one idea, or choosing what to build in a niche.

## About UnfollowerTrack

UnfollowerTrack is a website that checks a public Instagram account from its username alone. There is no Instagram login, no password, no app to install and no data download. The free first check shows real accounts from your follower and following lists, along with how many people you follow don't follow you back. Instagram itself only shows a falling follower count, not who left, so the site fills that gap by comparing lists.

With Premium, the site saves your follower list, keeps checking it on a schedule and emails you the name of each person who unfollows. Unfollows are tracked from the day you start Premium, so earlier unfollows cannot be recovered. The site also offers a report of your unfollowers, newest first, and a lookup of who a public account recently followed, with each new follow dated.

It is aimed at Instagram users who want to know who has stopped following them or who doesn't follow back, and at people who want to watch another public account's followers. Private accounts hide their lists and cannot be checked. The site states that checks use public data only and that nobody is notified.
