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.

Send It to Yourself Because sometimes the fastest way to remember something… is to email it to yourself. I built this app for one reason: I was tired of opening my inbox, tapping compose, typing my own email address, and waiting for the damn thing to send. No more subject lines. No more drafts. No more swiping through five different apps to jot something down. Just type what's in your head — or snap a photo, or record a voice note — and it shows up in your inbox. Instantly. Cleanly. Reliably. Why does this exist? Because I — like many people — use my email as a second brain. To-dos. Links. Notes. Book ideas. Shopping lists. Code snippets. Random thoughts at 2 a.m. Email is searchable. It's everywhere. And it works. But sending yourself an email shouldn't feel like filing your taxes. What this app does: • Type a note, snap a photo, or record a voice memo • Tap send — it's in your inbox in seconds • Jump straight in from the Share Sheet, a widget, or a long-press Quick Action — no need to even open the app • Save up to 10 destinations, so it's just as easy to send to a partner or shared inbox as it is to yourself That's it. No accounts. No logins. No clutter. What this app doesn't do: • It doesn't replace your email client • It doesn't send from your address — we use a fast, fixed sender for speed • It doesn't overcomplicate things with tags, folders, or rich formatting Free to try. Send a couple notes. See if it clicks. If it does, it's a few bucks a year. Less than a coffee. Way more useful. No ads. No tracking. No gimmicks. Just one button to send it to yourself. ---- InstaNotes Pro: • Send unlimited emails on a subscription basis • Your payment will be charged to your iTunes account upon confirmation of purchase • Your account will be charged for renewal within 24 hours prior to the end of the current period • You can easily manage your subscription and turn off auto-renewal in Apple's settings • Read the Terms & Conditions at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ • Read the Privacy policy: https://coffeeandjunk.notion.site/Privacy-Policy-c75b31be8f164b18b5ead4909126a6df You can email up to 3 notes for free. After that you'd have to purchase InstaNotes Pro.
