You're welcome! And yes, they are apps that should be seen as investments. I held the same reaction after seeing the prices for most of these apps many years ago. If you see yourself benefitting from using these apps for a long time it's worth the price they ask for in my opinion. Otherwise, there are free alternatives that may not be as feature-packed but if all you need is the basic functionality you should be good to go! Try looking at LastPass, I heard it's also good!
Also try
1Keyboard or
Typeeto if you want to type on your phone using your Mac keyboard. I find it very handy a lot of times. I have both installed at the moment; trying to get myself to decide which one of the two to keep and so far I find myself using 1Keyboard more. I guess it's because I had it longer than Typeeto.
Clear if you want a cool alternative to Reminders. I use it primarily for keeping grocery lists, remind me to do this and that later this evening, etc. If you're strictly on iOS, another alternative is
QUEST if you're into games.
Considering these are mostly paid apps and if you're interested in buying them, you're in great luck because aside from an App Store blessed with quality apps; many developers often take part in offering discounts during Black Friday week and holidays. You can bookmark
AppShopper and visit it for the next four weeks to see if anything you like gets a huge sale. To maximise efficiency, I suggest creating an account and search the paid apps you want and mark it as 'want' so you'll get an email when the particular app is discounted. Sometimes an app worth $49.99 can go down to as low as $1 or free.
Now... here are some
free apps that are also pretty good.
Alfred - I used to go crazy over this app until Apple finally updated spotlight in Yosemite. It's still good if you're willing to pay to enable workflows. Nonetheless, it's still a free app for the most part.
Vox - Music player alternative to the bloated iTunes. Also supports Apple Music AFAIK.
Transmission - It's better than uTorrent or any other torrent apps on OS X. Give it a shot; it's lightweight.
cDock - If you want to customise how your dock looks like.
LiteIcon - If you want to change your app icons. If you want to change icons for default apps like iTunes you first need to disable SIP, change the icons, and enable it back. It's a little bit of a hassle but it's worth it if you're not a fan of the default icons. For third-party apps that you installed there's no need to disable SIP.
AppCleaner - When you delete apps either via the Applications folder or Launchpad, there are usually small files left behind. They are in no way dangerous, but if you want a 'cleaner' uninstallation of apps you no longer want to use, you should use an app like this. I personally prefer AppDelete ($7) but this one is free and is just as good from what I heard.
coconutBattery - Shows you useful information about your battery. Highly recommended.
The Unarchiver - A replacement for the default Archive Utility app. It's a good app, but it falls short when it comes to RARs and other formats. The Unarchiver supports a lot more — Zip, Tar-GZip, Tar-BZip2, RAR, 7-zip, LhA, StuffIt, and many other old and obscure formats. This app feels like it's what Archive Utility should have been.
BetterTouchTool - Do you love your mouse or trackpad gestures? It's without doubt one of the best highlights of OS X. You'll love it more by utilising this. BTT allows you to configure many gestures for your Magic Mouse (1 & 2), Macbook Trackpad and Magic Trackpad (1 & 2) and also Mouse Gestures for normal mice.
Amphetamine - Override energy savings setting and keep your display awake for as long as you want. This is a newer (and good) alternative to Caffeine (an older app that does the same thing) — kick your coffee habit, take drugs instead! :rofl:
Phew... there's actually many more. I'll leave it for another day.
