ThinkBack is a simple tool designed to encourage memory building using spaced repetition. When you periodically repeat something you're more likely to remember it later. The act of repetition helps commit the information to long-term memory. Repetition can help you recall information when you need it. Random ideas, facts, lists — capture whatever you want, ThinkBack will prompt you daily at a time of your choosing to review them, moving your notes one step closer to long-term memory. What do we have to offer? - Privacy! We don't store your content on our servers. All content you enter into the app can be synced with your personal iCloud account. - Daily prompts to review one or more notes, moving them one step closer to long-term memory. - Group your notes into buckets using #hashtags. Quick, easy and flexible. - Search and filter capabilities make it simple to find the note you're looking for. - Mark a note as memorized to remove it from the daily recall rotation. - Pin your favorite notes to the top of the list. There's much more planned, we're just getting started! This app is free with an option to upgrade: I'm a small indie developer, but I don’t think it’s right to charge money unless you find value in the product. With that, a good bit of functionality is offered to you for free with the option to opt-in to more. If ThinkBack is helping make your life a little easier, upgrading costs less than 5 coffees per year. In-App purchase disclaimer: Should you decide to upgrade to Premium, a purchase will be applied to your Apple account at the time of upgrade. Subscriptions will automatically renew unless canceled within 24-hours before the end of the current period. You can cancel anytime with your iTunes account settings.
