Turn effort into rewards. ZanZan is a to-do list and habit tracker with rewards you choose. Plan your day, log reading or exercise, and earn Effort Coins using rules you set. Save up for a movie night, a coffee you love, or time for a game. Connect what you want to do with something to look forward to. You choose the activities, the coin rules, and the rewards. For example, you could earn 1 Effort Coin for reading a chapter and redeem a movie night for 20 coins. You decide what to do, how many coins to earn, and what to reward yourself with. TO-DO LIST & RECURRING TASKS Create one-time or recurring tasks for work, study, and daily life. Assign coin rewards to your tasks and earn them when you meet the rules you've set. HABIT TRACKING & ACTIVITY LOGS Log reading time, running distance, or other everyday activities. Create your own repeatable activities, add numbers, notes, and photos, and choose how each activity earns coins. CHOOSE YOUR OWN REWARDS Add a reward you'd enjoy, set its coin cost and requirements, and work toward it at your own pace. Redeem it when you have enough coins and meet the requirements, then look back through your reward history. EFFORT COINS & PROGRESS STATS Create different coin types for areas such as study, exercise, or daily life. See your balances, check where each coin came from, and follow your progress over time. FOCUS TIMER, WIDGETS & ICLOUD SYNC Start a focus timer when it's time to begin. Keep tasks and progress close with widgets. Store your data on your device, with optional iCloud sync. Start with one small task. Save up for something you want to reward yourself with. Effort Coins are for personal motivation within the app. They are not real money and cannot be exchanged for cash. You choose and arrange your own rewards; ZanZan does not provide or deliver prizes. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

It does not record call audio, block calls, negotiate debts, or file complaints for you.

INFORMATION, NOT LEGAL ADVICE Designed for U.S. consumers documenting debt collection activity. DebtShield is not a law firm and is not affiliated with the CFPB or any government agency. It does not provide legal or financial advice or determine whether a violation occurred. The call-frequency monitor screens logged counts against one CFPB Regulation F rebuttable presumption; it does not model all rules or exceptions. The FDCPA's 30-day validation period generally belongs to the consumer, not the collector. Checklist flags are not confirmed violations or a calculation of damages. A licensed attorney can assess your circumstances.
