You’ll find a huge repository of free apps here for various platforms including Android. GetJar is fairly basic, but apps are divided into categories and sub-categories within the store to make it easier to find what you want. You’ll also find likes or dislikes and comments on each app from users. GetJar can also connect with Facebook. On the downside, you will encounter sponsored recommendations, but they are clearly marked. Droid App
If an event isn't being organized on Facebook, it's probably being done through Eventbrite. This service makes it easy to manage invites, RSVPs, and even ticket purchasing. Attendees get handy reminders about the events they planned to attend, organizers can see guest lists. We particularly like that Eventbrite can generate QR codes, making event check-in a breeze.
If you're traveling within a major metropolitan area via either public transportation or personal vehicle, Citymapper can plan all your trip details. It has transit information for dozens of major U.S. cities and international hotspots in Europe, Asia, and Latin America. Further, it offers multiple transportation options for each city, so if you feel like taking the ferry to work one morning, there's nothing stopping you. Its top features include Commute, which lets you set up your daily travel to and from work, and an alert system that uses natural language to describe service delays or cancellations.
Your Gmail inbox is not secure. Use ProtonMail instead. This encrypted email platform offers a range of pricing options, including a free tier, so you have no excuse not to join. Security and privacy features aside, ProtonMail works like any other email app. Make sure to also check out ProtonVPN for securing your network traffic; it's an Editors' Choice for free VPNs.
File browsing is something everyone inevitably has (or wants) to do, so you might as well do it with a capable, fantastic file browser. Solid Explorer is pretty much as good as it gets in the file explorer apps realm. It features Material Design, archiving support, support for the most popular cloud services, and even some more power user stuff like FTP, SFPT, WebDav, and SMB/CIFS support. It looks great, it’s incredibly stable, and it just works well. There is a 14-day free trial with a $2.99 price tag at the end of it. This is, by far, the best file manager on Android for most people. Droid App
