Your twin,
with a phone of its own
Hand off phone chores in one sentence. Your Twin opens apps, taps, types and finishes the job on its own phone, while you keep using yours. One tap and you take over.
64-bit Android · No root required · Bring your own model API key
How it works
Three steps to hand it off
A few minutes the first time. After that, open Twoyi and say what you need.
Connect a model
Paste an API key from any model provider. It is encrypted and stays on this device.
Create the Twin phone
About 1 minute and 4 GB of storage gets you a separate, empty phone. You choose what to install and which accounts to use, or import apps from this phone.
Say what to do
Your Twin works through it step by step. You can also use the Twin phone yourself, come back, say a word, and it continues from that screen.
Features
Like handing your phone to someone you trust
It works where you can see it, you can step in at any time, and it asks before anything that matters.
One sentence, done step by step
Every tap, the reason for it and how long it took are kept in the chat. Change your mind halfway? Add a note and it applies from the next step.
Your screen stays yours
Your Twin works on its own phone while you keep scrolling and chatting. Leave Twoyi and the task follows you in picture-in-picture; you get a notification when it is done.
A separate phone
Nothing is copied from your main phone: no apps, accounts or private data. You decide what your Twin gets.
Take over anytime
Something looks off? Tap “Take over” and your Twin stops after the current step. Say a word when you are done and it picks up again.
Remembers what you like
What to call you, addresses you use, your preferences: say it once. Memory stays on this device and you can delete it at any time.
Asks before risky actions
Before deleting, paying, sending or posting, your Twin stops and asks. It goes on only when you say OK.
Sign-ins stay with you
For logins, passwords, verification codes and payment PINs, your Twin stops and asks you to handle it on the phone. It does not guess.
Sees the screen when needed
For games, video and other apps with no readable interface, your Twin can send a screenshot to the model. Needs a model that can see images.
Advanced
Or let your Twin use this phone
Rooted, or using Shizuku? Your Twin can open the apps already on your phone on a hidden background screen and act with your own accounts, out of the way of what you are doing.
- Android 14 or later
- Root (Magisk, KernelSU and others) or Shizuku
- Switch in settings; switch back to the Twin phone anytime, with everything kept
Models
Your model, your choice
Twoyi does not sell model credits. Bring your own API key from a provider you trust. The model must support tool calling; Twoyi tests it once when you connect and tells you the result.
Privacy
Where your data goes
Twoyi runs no model servers of its own and does not collect usage data. See the privacy policy for the details.
Your key stays on the device
Your API key is encrypted on this phone and never uploaded to Twoyi.
Screen content goes only to your model
During a task, the screen's text and layout, your instructions and memory (plus screenshots when “See the screen” is on) go straight to the provider you connected, not through Twoyi.
You decide about logs
Run logs and the steps of recent tasks are packed only when you tap “Send logs”, and you choose where they go.
Root mode: think once more
There your Twin works in the real apps on your phone, so their screen content goes to your model provider too.
FAQ
Do I need root?
No. The Twin phone runs as an ordinary app on your phone. Only the advanced “use this phone” mode needs root or Shizuku.
Which phones does it run on?
64-bit Android phones (Android 8.1 or later), with about 4 GB free for the Twin phone. Letting your Twin use this phone needs Android 14 or later.
What does it cost?
Twoyi is free during the public beta. Your model provider bills you for usage.
How is this different from a cloud phone?
The Twin phone runs on your own phone: no rented server, no monthly fee, and apps and data stay on your device.
Can I use apps like WeChat on the Twin phone?
You can install and use them. Some apps limit sign-ins across devices or have their own rules about automation; their terms decide what happens to your account, and Twoyi cannot vouch for them.
What if my Twin gets something wrong?
Every step is in the chat, and you can take over or stop the task at any time. It asks before deleting, paying, sending or posting (you can turn this off in settings). Actions already taken are not undone automatically.
How do I report a problem?
