Glad you got this done. You're going to use it for working and not get sucked into spending all your time in apps right?
A few things I find useful:
- ProtonVPN: the free version only has three countries (US, Japan and another I forget), but it's free and it's by the same guys who do ProtonMail so you can have some level of confidence that they care about privacy and security. In addition to fooling geolocation, this is also important when you use public wifi. Note that some public wifi hotspots won't let you connect to a VPN; to me this makes me believe they want to spy on you to gather more customer info in the best case scenario.
- A good searchable, cross-platform note-taking app: I mostly use Evernote, but have been transitioning to Microsoft's OneNote and also keep some trivial, unstructured stuff in Google Keep. "Notes" is not just text but can also include photos, scribbling and voice recording.
- A two-factor authentication app: I use Microsoft's Authenticator just to avoid having all my app eggs in Google's basket, but they are pretty much equivalent. Much more secure than SMS second factor.
- A password generator and storage app: I personally use a Keepass implementation with my own cloud storage, but there are some good options out there like Lastpass, 1password and Bitwarden (the last one would probably be my choice since it is open source)
- A good encrypted messenger: this depends somewhat on your circle of contacts since you all need to agree on the same one, but I like Signal. Depending on your exact needs, you might want to consider one that has self-destructing selfie capability
- An ad-blocking web browser: I use regular Firefox. Firefox Focus is also supposedly good.
Finally, not obscure, but you should probably install:
- Instagram: If you install this, you are basically selling every scrap of information about yourself to Facebook (in addition to having already given up everything to Google) but in return you will get to follow a plethora of fitness and bikini models. Essential if you want to be competitive in the GearMetalSolid challenges. I don't have this installed myself, so I don't know if recent versions are user-friendly or not.
- Personal information management: Depending on which exact phone you got, you might want to install Google's Calendar, Contacts, Clock, Gmail, Photos and Messages. I usually like them better than the apps manufacturers make themselves.
- Spotify: for obvious reasons if you listen to music
- Paypal: I kind of feel like PayPal is becoming less relevant over time as a way to transfer money, but it's probably still the most widely used and convenient method.
