weniger | Spar-Challenge

weniger helps your group make spending visible and stay accountable to shared savings goals. Instead of linking bank accounts, you track expenses manually. That keeps the experience simple, intentional, and privacy-conscious. Private challenges, rankings, and projections help you see how your day-to-day spending habits change over time. Whether you are a couple, roommates, or a group of friends, weniger makes it easier to compare progress, stay motivated, and spend more intentionally. Features: - private savings challenges - manual expense tracking with no bank connection - rankings and projections - invites for shared groups - optional push notifications - a one-time purchase for permanently ad-free use
