Welcome back to my monthly best Android apps list—this time for March 2026. I tested 15 awesome apps that can seriously upgrade your setup, from cleaner lock screens and smarter wallpapers to battery stats, spam blocking, and even Android TV utilities. I also show off MusWall, which finally gives Android that super clean “album art takes over the lock screen” vibe, plus Atmo Engine which brings the Nothing Phone-style lock-to-home wallpaper transition to basically any Android (and it’s free + open source). If you’re into practical stuff, OneBattery gives you a charging-only always-on screen with real wattage/current info, and Qota makes splitting receipts way less painful by scanning items and splitting costs (with flexible percentages per item). I also cover a bunch of quality-of-life tools: Auto Reply Calls to automatically text people after you miss a call, What’s SMS to reply via WhatsApp/Telegram/Signal instead of plain SMS, and Auto Mute to schedule-mute specific chats or even notifications with certain keywords. For calls, Call Guardian is great if spam is ruining your day, and Timeboard’s world clock widgets make time zones instantly readable with visual day/night bars. And if you’ve got an Android/Google TV, Sticky Note TV puts reminders right on the big screen, while Remote for Android TV is a faster, more reliable remote app. I saved the most powerful one for last: NoMone Desktop, which literally lets you run Linux on your Android device like a mini computer.
