Run two of most apps on one phone. Seven things Doppel does well, documented honestly.
Each instance is a genuine second copy of the app, with its own storage, its own cache, and its own files. Two WhatsApp instances can sign in to two different numbers and neither knows the other exists.
The separation happens for each instance on its own — your other apps and the rest of your phone are never touched.
A second launcher screen, gated behind biometrics or PIN. Move any instance in, and it stops appearing in the regular app list. The icon, the notifications, the storage — all of it tucked away.
You choose exactly which instances to hide, and it comes with Lifetime. Hidden instances are genuinely removed from your app list, not just tucked behind a toggle.
Built for Android 14 and newer, including the latest Pixel and other modern phones. The download stays small, so it installs quickly and is light on storage.
Doppel doesn't proxy, log, or observe any of the traffic between your app instances and their servers. We collect crash reports and basic usage metrics. That's it.
Full data inventory is on the Privacy page — every type of data, where it goes, and how long we keep it.
Doppel is an ordinary Play Store app. It doesn't change anything about your phone's system or the other apps on it.
An extra instance adds only modest memory use, and it opens at close to the speed of the original app. Doppel doesn't run a whole second system in the background.
If an app stops working after a new Android version, we can respond right away and get it working again for you — without you having to wait for a full app update.
