Intro is an app for things you want to remember. Intro brings together notes and contacts, in context. In Intro, the Global Timeline presents your latest info, right to hand for quick access. Keep track of people you meet. Intro is designed to help you keep track of people you meet, information you want to recall, and the links between them. Take quick notes, and link them to the relevant people, groups and events that make up their context. Add detail over time. Private by design. Intro is designed to be your 100% private knowledge store, when you need it. Intro provides sync using your private iCloud account, if you chose to enable it, but never sends any information anywhere else. We don’t copy your information to our servers… we don’t even have any servers. You are the only one with access to your data. For good. Advanced search options. Search people by physical characteristics you’ve tagged them with, or just with fragments of information you recall from their details or your notes. Track back through links and connections you’ve made to find that piece of information you need, whether it’s a name, an idea, a piece of information, or a promise. Manage contact info. Manage it within Intro privately, or optionally sync some or all of the people you add with the Contacts app. Or don’t sync anyone at all. It’s up to you. Learn your contacts’ names. Intro includes an errorless learning tool that trains your brain. It makes names stick. When you use this proven method, you’ll be amazed to find the names that you’ve learned will just come to mind when you need them. Real support. Intro offers real support, though a chat mechanism inside the app to get personal help from Intro’s developer, Dr Duncan Babbage. If you have a question, just ask. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Decision Maker

Features
Read full description

An application that helps you make accurate decisions based on reason and logic, so you are less likely to regret your choice. CORE FEATURES PROS & CONS This is a binary decision tool where you add positive and negative arguments. Each entry has a customizable weight, and the app calculates a net score to determine a "Yes" (Blue), "No" (Red), or "Undecided" (Amber) verdict. Key features: - Unlimited dilemmas, intuitive visuals - Add pros and cons and adjust their weight (importance) - Dark mode and light mode for you to choose - Your concerns will become transparent and clear COMPARE OPTIONS (DECISION MATRIX) This feature is designed for choosing the best option among multiple alternatives (e.g., iPhone vs. Samsung vs. Oppo vs. Xiaomi). You can define columns (Options) and rows (Criteria like Price, Battery). You rate each cell on a scale (1-10), and the app calculates a weighted sum to highlight the winning option. SWOT ANALYSIS This is a strategic planning tool for bigger picture thinking. It utilizes a 2x2 grid where you categorize factors into Strengths (Internal/Positive), Weaknesses (Internal/Negative), Opportunities (External/Positive), and Threats (External/Negative) to visualize the viability of a project or career move. 10-10-10 RULE This is a temporal framework to combat short-term emotion. It asks you to predict how you will feel about a decision in three specific timeframes: 10 Minutes, 10 Months, and 10 Years. This feature is text-based and reflective, helping you gain long-term perspective. The 10-10-10 rule can help you avoid FOMO (fear of missing out) and impulsive decisions, and minimize long-term regret. DECISION TREE For a choice with several paths, not just two. Lay each option out as its own branch, hang the reasons for and against it underneath, and weight them. The app scores every branch and shows which one is ahead, so a tangled decision becomes something you can actually see. OTHER FEATURES - The app supports both light mode and dark mode. Pick the one that fits your eyes. - The app can work totally offline. No internet connection is required. - You can export your data into a JSON file for backup (e.g, when you change your phone) or import/ restore your old data. - The app supports local authentication. You can use Face ID to lock the app to keep your decisions private.
