The 52 Weeks Challenge is a really simple savings plan that helps you save a minimum of $1,378 by the end of the year. With the 52 Weeks Challenge, you start by saving $1 the first week. Then you gradually increase it to $2 the next week, $3 the week after and so on and work your way through up until the last week of the year at $52.

Make the 100 envelope savings challenge a little more fun. Pick one of the shuffled envelopes, reveal an amount, and record the money you put aside. PICK. SAVE. FILL YOUR ENVELOPES. Open today's envelopes and choose one of up to three. Save the amount shown wherever you keep your money, then mark it as saved in the app. Revealing an amount does not mark it as saved. You can return to the same envelope when you're ready. A COLLECTION YOU CAN WATCH GROW See all 100 envelopes together. Each completed envelope adds another little sign of progress. Zoom in to explore the collection and check individual records. YOUR GOAL, AT A GLANCE Keep your saved total, remaining goal, current streak and this week's savings in view. Your savings calendar, weekly chart and daily history help you see the habit you're building. A SAVINGS CHALLENGE THAT FITS YOU Choose 50, 100 or 200 envelopes, try a 52 week savings challenge, or create a custom challenge with your own envelope count and amount range. Track several goals, choose a currency and set a daily reminder. YOUR IPON CHALLENGE, YOUR CURRENCY Saving in pesos? Choose PHP for your ipon challenge. USD, EUR, KRW, JPY and other supported currencies are also available. YOU KEEP THE MONEY. THE APP KEEPS THE RECORD. This is a savings tracker, not a bank account. It does not hold or transfer money. Savings records are stored on your device and can be viewed and updated offline. Ads and usage analytics use an internet connection. If a smaller unopened envelope is available, you can choose to watch a rewarded ad for one random smaller replacement. The original envelope stays available for later. Start with one envelope and watch your collection grow.
