A challenge isn't about "changing your life in a month." It's about "trying 30 days and seeing what happens." ChallengeUp is an app for short challenges: ready-made ones from 7 to 90 days, custom ones for any length. No endless "lifelong" trackers, no promises of a "new you." Just a clear format: pick a challenge, cross the finish line, see the result. WHAT'S INSIDE 10 ready-made challenges, free. From "no sugar" to "sleep before midnight," from "read every day" to "learn a foreign language." Each one comes with a clear description — what to do, why, and what to expect. Build your own in 30 seconds. Name, duration, frequency, reminders — and you're ready. No required fields, no endless setup screens. A finish line that motivates. Every challenge ends. It's not the "forever habit" that wears you out by week three. It's a defined distance with a finish — and the feeling of "I did it." Progress cards for social media. Share your wins with people who matter — close ones, friends, followers. Get support when you need it, and lock in the result by saying it out loud. The cards are drawn so they're a pleasure to share. No ads. Ever. Not in the free version, not anywhere else. ChallengeUp Plus When the free version isn't enough: — Unlimited active challenges (up to 3 in free) — Expanded catalog of exclusive challenges, with more added over time — Duration up to 1000 days — nearly three years of practice, for those who want to go long — Home screen widget — Additional colors and customization — Support for an independent dev team WHY A CHALLENGE Most habit trackers are built on the idea of a "forever" habit — you should brush your teeth or meditate every day for the rest of your life, and a single miss breaks everything. This rarely works, because the brain isn't built for infinite distances. According to Lally et al. (2009), a stable habit forms in about 66 days, not the often-cited 21. A short challenge is a way to cover that distance without burning out: with a visible finish, and the right to stop if it's not for you. ChallengeUp is an independent app. We're not building "another habit tracker." We're building the app we'd want to use for our own challenges: no fluff, no features for the sake of features, no pointless push notifications. Just what works.
