I've been going back and forth between using Apple apps for what I call "Core" functionality - Calendar , Email, Web Browsing, Task management, Note Taking, Photo Management , and 3rd party apps that do the same thing. I look at Mac OS and iOS apps, so it was difficult to decide where to put this post. I chose Mac Apps forum. In each case, I ended up using both, which is redundant but gets me the features of both. Here is my list - # Calendars * Apple Calendar - Travel Time, Time to Leave, and the ability to click the map on the appointment to start Apple Maps ( ios only ) * Fantastical 2 - Natural language to enter appointments, list view of upcoming appointments. Quick appointment entry in Menu bar ( Mac only ) # Email - * Apple Mail - identifies updated contact info, meeting info, locations, and ( I think ) travel itineraries . * Airmail - Custom Tasks ( ios only ) , sync signatures across devices, store email account settings in iCloud and unlock all of them with just your Apple id, Music * Apple iTunes / Music App all the way - Apple Music service rocks, library sharing, and the huge selection is great. # Note Taking _I'm all over the place here_ * Apple Notes - Simple. iCloud sync. * Byword - iCloud Sync, Markdown support * Evernote - Cloud sync, Tags , Notebook stacks , saved searches. - basically, I really like it except for lack of Markdown support. # Photo Editing _I don't do much of this_ * Apple Photos - iCloud Storage, Organize Photos, tag, Markup(ios only), Face recognition. * Pixelmator - Layering , advanced editing tools. * Photosweeper - deletes duplicat photos from Photos. * Preview - Quick view/editing of Photos that are not in Apple Photos library. This app is much more powerful that most people think. Google it! # Podcasts * Apple Podcasts - I never use it. I re-try it periodically because I like that it sync's between Macs and iOS devices, but they refuse to add the 2 features that I want the app, despite me submitting feature requests every year. * Pock Casts - Silence trim. Voice boost. Sync's across iOS devices, syncs some data with their Desktop app. I use this app daily. # Task Management * Apple Reminders - Simple. iCloud sync. Siri integration. Many apps can sync with it - IFTTT,OF, Amazon Alexa, so on. * Omnifocus - Great for GTD, frequent updates, locations, contexts ( soon to be tags ), projects, just a ton of great features. I tried several competitors to try and on that works on Windows, but nothing else comes close. # Web Browsing * Chrome - Works on Macs and PC ( Windows, Linux ). Huge array of Extensions to choose from. * Safari - Keychain for passwords and payment info, Reading List, Native text shortcut support. While I'd really love to go "all Apple" and use the free apps that they provide, they fall short in some area that is important to me. Post your list or apps that you prefer to use in this thread.
