XDA published a piece on the four apps their writer installs on every new Galaxy, and it got us thinking. Samsung’s One UI ships with a lot of good stuff already: a solid launcher, a clock app that shows sunrise times, and Bixby Modes and Routines for automation. But there’s a small set of apps we install on a fresh Galaxy S25 or A56 before we transfer anything else. These are the best apps for a new Samsung Galaxy phone, tested on One UI 7 and 8 across the S, A, and Z lines.
We evaluated candidates by what they add over the built-in tools, whether they respect battery on Samsung’s Wallet-style black-panel display, and whether they play well with Good Lock’s customization layer. Two of the picks are Samsung’s own; the rest come from third-party developers.
What to look for in a Galaxy-first app
Samsung’s software situation is unusual: One UI does more out of the box than stock Android, so the bar for a third-party install is higher. Good candidates avoid duplicating what One UI already ships (there’s no reason to install a third-party clock or calculator), integrate with Good Lock modules where possible, and don’t waste system RAM on features you get elsewhere. Battery drain matters more on Galaxy hardware because Samsung’s One UI is aggressive about background limits, so any app that gets killed constantly is a poor fit.

The apps
1. Samsung Good Lock, best for unlocking One UI’s hidden layers
Samsung Good Lock is the app Samsung itself keeps quiet about, and it’s the single most useful install for a new Galaxy. Modules like LockStar, Wonderland, NavStar, and QuickStar let you retheme every screen One UI touches. Sound Assistant separates audio per app. Routines+ extends Modes and Routines with triggers Samsung’s default UI won’t surface.
Where it falls short: Samsung-only. Some modules take a beat to update after a One UI release. If you don’t want to tinker, Good Lock’s shelf of modules can feel like homework.
Pricing:
- Free: Fully free, no ads on any module
Platforms: Android on Samsung Galaxy devices only
Download: Aptoide · Samsung Galaxy Store
Bottom line: Install it first, before anything else. Every future Good Lock module unlocks more One UI power.
2. Modes and Routines, best for phone automation without Tasker
Modes and Routines ships pre-installed on Galaxy phones but sits three menus deep. Surface it from Settings, and you get IFTTT-style automation with triggers Samsung has direct access to: charging state, Wi-Fi network, calendar events, and physical button presses.
Where it falls short: Doesn’t reach as deep as Tasker for power users. Some triggers depend on Samsung services being enabled.
Pricing:
- Free: Pre-installed on Galaxy phones
Platforms: Android on Samsung Galaxy devices only
Download: Pre-installed. Search “Modes and Routines” in Settings.
Bottom line: Turn it on the day you unbox the phone. Add a “Sleep” mode that mutes notifications after 11pm and you’ve already got value.
3. Nova Launcher, best for a custom home screen
Nova Launcher is the Android launcher your friend has run for a decade. On Samsung, it plays nicely with One UI gestures, respects Good Lock’s LockStar theming, and lets you set icon packs, custom grids, and gesture shortcuts the OneUI Home launcher hides.
Where it falls short: Development slowed after Branch acquired Nova in 2022, though maintenance continues. Some Galaxy widgets (weather, calendar) don’t stretch the way they do on OneUI Home.
Pricing:
- Free: Full launcher, all core features
- Prime: $4.99 one-time for gesture shortcuts, icon swipes, and unread badges
Platforms: Android
Download: Aptoide · Google Play · Samsung Galaxy Store
Bottom line: The Nova Launcher for a new Samsung Galaxy is still the least disruptive way to redesign your home screen without abandoning One UI’s core features.
4. Bitwarden, best free password manager and passkey vault
Bitwarden is the free open-source password manager we recommend even to people who use Samsung Pass. Cross-device sync is free, passkey storage is included on the free tier, and the browser extension for Samsung Internet works properly.
Where it falls short: The autofill on Samsung Internet still trips on some forms. The UI is functional rather than pretty.
Pricing:
- Free: Unlimited passwords, cross-device sync, passkeys, 2FA
- Premium: $10/year for email report tools and 1 GB of encrypted file attachments
Platforms: iOS, Android, Windows, macOS, Linux, browser extensions
Download: Aptoide · Google Play · App Store
Bottom line: Skip Samsung Pass unless you’re locked into a Samsung-only life. Bitwarden gives you passwords across every browser and machine you’ll ever use.
5. Microsoft SwiftKey, best keyboard for Samsung’s stock replacement
SwiftKey is the keyboard Samsung’s own team recommended for years. Swipe typing is more accurate than One UI’s Samsung Keyboard in our testing, multi-language typing switches with no fuss, and the number row at the top is on by default.
Where it falls short: Owned by Microsoft, which some people avoid on principle. Newer AI features push a Copilot button into the keyboard.
Pricing:
- Free: All keyboard features
Platforms: iOS, Android
Download: Aptoide · Google Play · App Store
Bottom line: The best free keyboard on Android in 2026, especially for anyone who types across two or more languages.
6. Solid Explorer, best paid file manager
Solid Explorer is the file manager for people who move files. Two-pane view for drag-and-drop, native cloud connectors for Dropbox, Google Drive, OneDrive, Nextcloud, and SMB, and support for ZIP, RAR, 7z, and encrypted archives.
Where it falls short: One-time purchase, no free version after the trial. Some cloud connectors need a paid add-on.
Pricing:
- Free: 14-day trial
- Paid: $2.99 one-time
Platforms: Android
Download: Aptoide · Google Play · Samsung Galaxy Store
Bottom line: If you move a lot of media between your phone and a NAS, Solid Explorer earns its price in an afternoon.
7. AccuBattery, best for tracking real battery health
AccuBattery measures your actual battery capacity over time and gives you a healthy-charge threshold. Set the alarm at 80 percent, and the app pings when it’s time to unplug, which pairs perfectly with Samsung’s own “Protect battery” toggle.
Where it falls short: Some readings need a few full cycles before they stabilize. Doesn’t have deep root-level insights other apps offer.
Pricing:
- Free: Charge tracking, health estimates, alarm at 80 percent
- Pro: $4 one-time for dark theme, discharge history graphs, and extended metrics
Platforms: Android
Download: Aptoide · Google Play
Bottom line: Two years from now, the phone you kept below 80 percent will still hold a charge. This is the app that trains that habit.
8. Poweramp, best local music player for Hi-Res audio
Poweramp is the local music player we install every time a Samsung phone with a good DAC lands on the desk. Hi-Res output up to 32-bit float, gapless playback, and a proper 10-band graphic equalizer. Poweramp for a new Samsung Galaxy pairs especially well with Galaxy Buds Pro’s Scalable Codec.
Where it falls short: The UI is dense on purpose. No first-party streaming. Trial nag if you don’t buy.
Pricing:
- Free: 15-day trial
- Paid: $5 one-time full unlock
Platforms: Android
Download: Aptoide · Google Play · Samsung Galaxy Store
Bottom line: For anyone who owns a Hi-Res library or a good pair of wired IEMs, this is the local music app on Android.
How to pick the right one
If you want the fastest wins, install Samsung Good Lock and turn on Modes and Routines in the first ten minutes.
If you’re rebuilding a home screen you liked on your old phone, Nova Launcher is the smoothest transfer path.
If you’re serious about security, Bitwarden goes on before you log into anything else.
If you type in more than one language, SwiftKey beats the Samsung Keyboard on daily accuracy.
If you keep your phone for four years, AccuBattery is the cheapest longevity insurance you’ll find.
FAQ
Do I need Samsung Good Lock on a new Galaxy phone?
Only if you plan to customize One UI beyond wallpaper and font. Good Lock’s LockStar, NavStar, and Sound Assistant modules unlock changes One UI Home hides.
Is Samsung Pass better than Bitwarden on a Galaxy phone?
Samsung Pass is more integrated into One UI biometrics, but locks you into Samsung Internet and Samsung’s ecosystem. Bitwarden is the better long-term pick because it follows you across every device and browser.
Which apps drain the least battery on Samsung phones?
Bitwarden, AccuBattery, and Solid Explorer all run cold in the background under One UI’s aggressive battery limits. Poweramp uses more when actively playing, which is expected. SwiftKey and Nova Launcher are always-on and consume a percentage of battery daily.
What’s the best free keyboard for a new Samsung Galaxy?
SwiftKey. It’s still the most accurate swipe keyboard, handles multilingual typing without setup gymnastics, and it’s free.
Do these apps work on Galaxy foldables and tablets?
Yes. All eight run on Galaxy Z Fold, Z Flip, and Tab S devices. Good Lock’s MultiStar module in particular is designed for large-screen Samsung hardware.
