Do you try to save money regularly? But find it boring or hard to succeed? With Sparkalender it will be much more fun and easier. Let's say you want to save for a vacation. You create a saving and select how often you want to save money. For instance, every week for 3 months. Then Sparkelender will randomize how much you should save each week for the upcoming 3 months. You get notified when it's time to save, and you select based on what you feel you can afford that week. One's economy isn't the same each week and with Sparkalender you can select more money when you just got paid and less if you spent the nights out with friends and have less to save that week. FEATURES - Notifications when it's time to save - Much easier to succeed when you select the amount you can afford - Have multiple savings running at the same time - Add days when you can skip to save (for instance, Christmas is coming up, and you want to skip saving money during the holidays) - Edit an ongoing saving in case you want to move the target or the amount you want to save - Save weekly, biweekly or once a month. Whatever suits you the best SECURITY Your security is very important to us, so Sparkalender is NOT connected to any sort of bank or other app. Sparkalender simply gives you the amount you should save, but you have to move the money yourself. Maybe it feels a bit extra, but security is more important to us than implementing such a feature. SUPPORT We are eager to hear from you. We just love to hear both good stuff and bad stuff. And it's very likely that your opinion will be added to the next update. Please don't hesitate to contact us from within the app. Terms of use (EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
