The Best Android Apps to Install on a New Phone

A new phone comes with Google's own apps already on it, and most of them are good enough. The best Android apps to add on day one fill the gaps those defaults leave: a real password manager, private messaging, a browser you can extend, offline maps, and a way to move files to a computer without a cable.

This list is built from research rather than hands-on testing. Every pick was checked against its current Google Play listing and developer documentation in October 2026, and each entry says who it suits and what the catch is. None of the nine relies on intrusive ads, and most are free or open source.

Security first

1. Bitwarden

Best for: anyone still reusing passwords or relying only on a browser's built-in password saving.

Bitwarden stores logins, generates strong passwords and fills them into apps through Android's autofill service. It also creates and syncs passkeys across the mobile app and its browser extensions, which matters as more sites drop passwords altogether. The core app is free with no ads, and paid Premium plans add extras on top. If you'd rather keep everything with one privacy-focused company, Proton Pass is a strong alternative: its free tier works on unlimited devices and includes a handful of hide-my-email aliases, though its built-in 2FA code generator is a paid extra.

The catch: a password manager is only as safe as its master password. Pick a long one and turn on two-factor login for the vault itself.

2. Aegis Authenticator

Best for: people who want their two-factor codes in a local, encrypted vault instead of tied to a big-tech account.

Aegis is a free, open-source authenticator that supports the standard TOTP and HOTP code formats, so it works anywhere Google Authenticator does. The vault can be encrypted with a password or unlocked with your fingerprint, and it can make automatic backups to a folder you choose. It can also import from Google Authenticator, Microsoft Authenticator, Authy and others.

The catch: Aegis is Android-only and doesn't sync to the cloud on its own. Set up those automatic backups, or a lost phone means a long afternoon of account recovery.

Talking and browsing

3. Signal

Best for: private one-to-one and group chats with friends who'll install one more app.

Signal end-to-end encrypts messages, voice and video calls by default. It's run by a nonprofit, the Signal Foundation, and funded by donations rather than advertising, which is why the "in-app purchases" label on its Play listing refers to optional donations, not paywalled features.

The catch: it's only as useful as the number of people you know on it.

4. Firefox

Best for: people who want ad and tracker blocking without switching to a niche browser.

Chrome on Android phones still doesn't support extensions. Firefox does, so you can install a content blocker and other add-ons directly on your phone. It blocks many cross-site trackers by default and can lock private tabs behind your device's screen lock. If you use Firefox on a computer, bookmarks, history and passwords sync between them.

The catch: some sites are built and tested mainly for Chrome, so expect the occasional layout quirk.

Files and transfers

5. Files by Google

Best for: clearing space and sending files to nearby Android phones.

Many phones ship with it, but Samsung, Xiaomi and others use their own file apps, so it's worth installing. Files by Google suggests what to delete (duplicates, old chat media, junk files), handles offline transfers through Quick Share, and has a locked folder with a PIN or pattern separate from your screen lock. If you want more control, our roundup of file manager apps for Android covers the power-user options, and the storage cleanup guide walks through the full process.

6. LocalSend

Best for: moving files between your phone and a Windows, Mac, Linux or iPhone device on the same Wi-Fi.

LocalSend is open source, needs no account or internet connection, and encrypts transfers over your local network. Install it on both devices and they find each other automatically. It fills the gap Quick Share leaves when the other device isn't Android or a Chromebook.

The catch: both devices need to be on the same network, and some public or office Wi-Fi blocks devices from seeing each other.

Maps and media

7. Organic Maps

Best for: travel, hiking and anywhere with poor signal.

Organic Maps uses OpenStreetMap data and works fully offline, including search and turn-by-turn navigation. Map downloads are free and unlimited, there are no ads, and it doesn't send data in the background. It's a good backup to keep next to Google Maps for trips abroad where roaming data is expensive.

The catch: it's built on volunteer map data, so it won't match Google Maps for business reviews, opening hours or live traffic.

8. Pocket Casts

Best for: anyone who listens to more than a couple of podcasts.

Pocket Casts, owned by Automattic, is free and covers what most listeners need: playback speed controls, an OLED-friendly dark theme, Android Auto support and OPML import and export so you can bring your subscriptions over. A paid Plus tier adds extras, but the free app isn't crippled.

The catch: the extras that tempt you to upgrade, such as desktop apps and cloud file storage, sit behind Plus.

9. VLC for Android

Best for: playing video and audio files your default player refuses.

VLC plays almost any format, handles subtitles, and can stream from network shares on your home network. The developers state plainly that it has no ads, no in-app purchases and no tracking, and the source code is public.

The catch: the library view is functional rather than pretty.

What you probably don't need to install

Skip "phone cleaner," "RAM booster" and "battery saver" apps. Android manages memory itself, and these apps tend to carry heavy ads and broad permissions. The same goes for third-party antivirus on a phone that only installs from Google Play, since Google Play Protect already scans apps. Spend ten minutes in your phone's own settings instead. Our checklist of Android privacy and security settings and our list of Android features most people never turn on will do more for a new phone than any cleaner app.

A sensible first-day setup

If you only install three things, make them Bitwarden, Aegis and Signal. They protect your accounts and conversations, and they're the hardest to retrofit later. Add Firefox if you want ad blocking, and Organic Maps before your next trip. For tasks and calendars, see our separate guide to productivity apps for Android.

Before you finish, open each new app's permission screen (Settings > Apps, then the app, then Permissions; the exact path varies a little on Samsung, Xiaomi and other skins) and turn off anything it doesn't need.
