What is the 100 Day Challenge? The 100 Day Challenge helps you work consistently toward your goals and build real habits. Instead of big leaps, it's about small, daily steps that add up over 100 days and bring lasting change. Key features: • Multiple challenges at once: Start and manage different 100-day challenges in parallel (e.g., reading, sports, learning, meditation). • Daily completion: Mark your progress with just one tap – “Today done” keeps your streak alive. • Visualization: See your progress at a glance: expanded view with 100 days, checked days in green with check marks. • Motivating main screen: Personal greeting, overview of all active challenges, progress indicators, and quick selection. • Icon selection per challenge: Choose a suitable icon for each challenge. • Progress rewards: Visualize milestones and stay in the flow. • Pro version (in-app purchase): Unlock all features, remove restrictions, and get additional personalization options. Why does it work? Because small, daily actions done consistently are more effective than sporadic motivation. 100 days is short enough to stick with and long enough to form real habits. Social accountability – use it to your advantage: Share the start of your challenge on social media or with friends. Post at the beginning and after important milestones – this creates gentle social pressure that motivates you to stick with it. Others know that you have started, and you don't want to break the streak. Privacy & Sync: All data is private and stored securely in your iCloud account. There are no central servers; your challenge data belongs only to you. Tips for maximum impact: • Choose clear, specific tasks (e.g., “read for 10 minutes” instead of “read more”). • Use multiple parallel challenges, but don't overload yourself – focus helps. • Check your streak regularly to avoid setbacks and maintain motivation. Upgrade to the full version: Unlock the full power: unlimited challenges and no restrictions on the number of days. Support & feedback: Do you have any ideas or need help? Write to us directly via the app or visit our support page (link in the app). Your feedback makes the challenge better.

Remember everything — without the effort. Note Recall is where you put anything you don't want to forget: ideas, plans, thoughts, facts, moments. Jot it down however you like — no folders, no format, no journaling habit to keep up. Note Recall organizes it for you, connects related notes, and hands the right one back the instant you need it. And you don't have to be the only one writing things down. The people who help you — family, friends, or a professional caregiver — can add notes to your app too. No account. No sign-up. No ads. No AI charges. No daily limits. CHAT WITH YOUR NOTES Ask a question in plain language and get an answer grounded in what you actually wrote, with the source notes cited. It's like having a search bar that understands you — no more scrolling to find that one thing you jotted down weeks ago. INSIGHTS THAT SURFACE ON THEIR OWN Note Recall notices recurring themes, follows up on intentions you set ("did that stick?"), and gently surfaces patterns across everything you've captured — so you see the bigger picture without doing any extra work. FAMILY, FRIENDS, AND CAREGIVERS CAN ADD NOTES FOR YOU This isn't just for professional care. A son or daughter, a spouse or partner, a sister, a neighbor, a home health aide — anyone you invite can send a note straight into your Note Recall. "The A/C repair man is coming Tuesday at 10." — added by Sarah They never need an account or a subscription — they install Note Recall, you send them one invitation, and from then on they write you a note right inside Messages, the same way they'd text you. It arrives with their name on it and works exactly like a note you wrote yourself — ask Chat about it later, and it shows up in your Insights too. You stay in charge of all of it. Every note waits for your OK before it's saved, you choose who is allowed to send, and you can remove anyone at any time. Invitations are required — a stranger can't add anything — and notes are encrypted so only your device can open them. PRIVATE BY DESIGN - The AI runs entirely on your device. Your notes are never sent to us or any AI service — we don't even have servers. - No account. No sign-up. No ads. - Your notes stay on your device and, if you turn on iCloud, sync privately across your devices through your own iCloud account. BUILT FOR EVERYDAY USE - A home-screen widget to capture a note in a tap - Light and dark mode - Fast, offline, and yours. Chat and Insights work without Internet access. TRY BEFORE YOU SUBSCRIBE Turn on Demo Mode to explore Chat and Insights on a set of sample notes before you commit — no strings attached. FREE & PRO Note Recall is free for up to 10 notes. Subscribe to Note Recall Pro for unlimited notes; everything else works exactly the same. - Note Recall Pro (Annual): unlimited notes - Payment is charged to your Apple Account. The subscription auto-renews unless canceled at least 24 hours before the end of the period. Manage or cancel anytime in your Apple Account settings. Note: on first launch Note Recall downloads its on-device AI model (a one-time download over Wi-Fi). Nothing you write ever leaves your device. Requires: - iPhone 15 Pro, or any iPhone 16 or newer - iPad with an M-series or A17 Pro chip (These are the devices with the 8 GB of memory the on-device AI needs.)
