Nine is a very reliable email client designed to work with all of your accounts. The clean interface and the optional conversation view make reading and replying to email intuitive. One of the coolest features is the ability to customize the notification actions, including an incredibly useful "Mark as read" option. It isn't cheap, but it's only a one-time $14.99 charge for a much-improved email experience that also integrates calendar, contacts, notes, and tasks functionality. Droid App
If you like to keep your life organized with various to-do lists, then you definitely need to download Todoist. This app lets you keep track of the tasks you need to get done; you can assign them different priorities based on their overall importance or organize them across different projects. It also has a functional, clean design and works across many different platforms. Anyone can get started for free, but seriously organized individuals should upgrade to the $28.99 per year premium plan to set up task labels and reminders, upload files, and view productivity charts.
Google Maps virtually owns the navigation apps scene and it remains of the best Android apps ever. It gets frequent, almost weekly updates that seem to only add to its incredibly generous list of existing features. Aside from the very basics, Google Maps gives you access to places of interest, traffic data, directions to things like rest stops or gas stations, and they even let you have offline maps now (albiet temporarily). If you add to that the Waze experience, which includes tons of its own features, and you won’t need another navigation app. Ever. Google also owns and operates Waze. It’s unique and fun in ways that Google Maps isn’t and we also highly recommend it. Droid App
Don't get us wrong, some of us love Instagram. But if you want more control than Instagram affords, try Google-owned Snapseed. This app straddles the line between full-fledged image editor and filter app, all in a sleek and attractive package. Best of all is the amount of control it gives you over how filters and effects are applied to your images. It even lets you make non-destructible edits to raw camera files and make adjustments to exposure and detail levels. Droid App

Zocdoc even saves your history of appointments and makes recommendations for future ones, so you can stay on top of your health history.
Remember the bad old days of ordering food? You needed takeout menus, knowledge of the terrain ("will they even deliver out here?"), cash, and faith that the person jotting down your order got it right. Seamless takes care of all that, even letting you pay via credit card from your Android. The only drawback? It's not available in every city (or even every state), though it has expanded its range dramatically since it was first included on this list. Droid App
