About Sims Challenge Tracker
building SimsChallengeTracker.com
Sims Challenge Tracker was built by Calendula Petals, a long-time Simmer with a passion for Sims 4 challenges. Calendula Petals uses Sims Challenge Tracker themself to track multiple challenges (and even uses it as a reference), and so the graphical challenge tracking tools and references were built with everyday Simming in mind.
Signing up to track your Sims 4 save files is free, and so are the references. Support Sims Challenge Tracker today to keep the site free from ads and fees. Your donation helps to pay for hosting, backups, and new development.

So I built that first. It's done, I just d...
