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/

Verdict

The call

The clearest difference is rating: Intro at 5.0 against Calculator Widget's 4.3. Intro also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). Calculator Widget's advantage is in-app purchases (none vs 2) and review sentiment (100% vs 67%). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Intro holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 4 and 15 respectively. Written reviews complicate that: 67% of Intro's written reviews are positive against 100% of Calculator Widget's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Intro ships an update every 3 weeks, Calculator Widget every 2 months. The most recent releases landed on October 16, 2026 and October 4, 2026 respectively.
