ALPHA COHORT · FIRST 20 CAREGIVERS
Does your parent live alone with an Android phone? Help us watch over them.
StillFine is a quiet, no-hardware safety net for elderly parents. We're inviting the first 20 caregivers to help shape the alpha — your real-world feedback is what makes this app real.
📱 Only your parent's phone needs to be Android (Android 8+).
You can use an iPhone, an iPad, or any browser to view the dashboard.

📱 You don't have to own an Android phone to help.
StillFine is installed on the senior's phone — the one whose activity we monitor. You, the caregiver, can use any phone (iPhone is fine), tablet, or web browser to view the dashboard. Most of our friends are on iPhone too — that's why we wrote this page. If your parent or grandparent uses Android, you can be the caregiver.
Why we built it
Every year, seniors living alone experience falls, strokes, or quiet medical events that go unnoticed for hours — sometimes days. Smartwatches end up in drawers. Cameras feel invasive. Most families just call and hope nothing's wrong.
StillFine turns the phone your parent already uses into an invisible guardian. No new device. No camera. No GPS. Just a calm signal that says: they're still fine today.
"We built StillFine for our own parents. They didn't want a wearable. They didn't want a camera in the house. They didn't want to be tracked. But they were happy to keep using the phone they already had. That was enough."

How it works — without your parent changing a thing
The phone already knows when it's picked up, when the screen is unlocked, when the charger is plugged in, when its owner walks around. StillFine notices these everyday signals and quietly tells you: "Yes, today is a normal day for Mom."
If a long stretch passes with no signal, the app first sends your parent one gentle nudge: "Tap to let your family know you're okay." One tap dismisses it. Only if they don't respond does you, the caregiver, get an alert.
Most days, you'll hear nothing. That silence is the product working.
What you get as the caregiver
- Six-layer Android monitoring — accelerometer, screen unlock, charging, hardware significant-motion, step counter, and silent server probes. If one layer is throttled by the OS, the others still work.
- Three-stage smart alerts — gentle nudge to your parent first, then a family alert, then escalation to others on your trusted list. Default 6 hours. You set the timing.
- Web dashboard works anywhere — iPhone, iPad, laptop, any browser. No app needed on your end.
- Family-shared — siblings, neighbors, trusted friends can all stay in the loop without calling and interrupting.
- Sleep-aware — quiet hours mean no false alarms while your parent rests.
- Bilingual — full English and Chinese support. The right server is picked automatically based on your parent's location.
What your parent gets — without changing anything
🤫
Nothing to learn
No buttons to press. No app to open. They keep using their phone like always.
⌚
Nothing to wear
No bracelet, no pendant, no smartwatch to charge or remember.
🛡️
Dignity preserved
No camera. No microphone. No GPS. You see "she's having a normal day" — not where she is or what she's doing.
😌
Fewer "are you okay?" calls
Calls become warm conversations, not duty check-ins. Both sides feel better.
😴
Sleep stays sacred
Quiet hours mean no alerts at night. Their sleep is their own.

Help arrives if needed
If something is wrong, you know quickly — instead of hours or days later.

🌱 Why we keep this batch small
The first 20 caregivers shape the foundation. We read every piece of feedback — what's confusing, what's missing, what's magical, what's broken — and bake it into the next version. Once these 20 spots fill, we may open a second batch, but the conversation we have with this first group is the one that decides what StillFine becomes.
How to join — five minutes
- Email us at [email protected] with the Google account email used on your parent's Android phone. We'll add that account to the Closed Testing list within one business day.
- Watch for our reply — it includes a one-tap "Become a tester" link. Open that link on your parent's phone (or in any browser signed in to their Google account), tap Become a tester. This unlocks the alpha build in their Play Store.
- Install StillFine on your parent's Android phone from the Play Store. Open the app — you'll see a "Scan QR Code" button. Leave that screen on; you'll come back to it in step 5.
- Create your caregiver account at stillfine.ai on your own device (any browser — iPhone, iPad, laptop). Walk through the senior-setup wizard; the last step shows a QR code on your dashboard. Keep that screen visible.
- Scan the QR code — pick up your parent's phone, tap "Scan QR Code" in StillFine, point its camera at the QR on your dashboard. Done — monitoring starts immediately.
- Tell us anything you find — confusing, missing, magical, or broken. That is the whole point of this stage.
Note: the Google-account opt-in is a temporary Closed Testing requirement. Once StillFine launches publicly, install will be as simple as any Play Store app.
FAQ
I have an iPhone — can I still be the caregiver?Yes. The caregiver dashboard runs in any web browser. Only your parent's phone (the monitored phone) needs to be Android.
I have an Android phone too — can I install on my own phone first to try it out?Yes. Send us your own phone's Google account (instead of, or in addition to, your parent's) and we'll add it to the tester list. You'd install StillFine on your phone for the test, with the caregiver dashboard open in a laptop browser. When you're ready, you can install on your parent's phone and run them side-by-side.
What if my parent isn't comfortable with technology?That's expected. Setup takes about 2 minutes and you can do it for them — they don't need to know how the app works. After setup, they don't have to do anything.
Will it drain my parent's battery?The app uses Android's hardware-level sensors which are designed for low power. In our testing, battery impact is similar to a normal background app.
What about my parent's privacy if my siblings also see the dashboard?Family members only see "active recently" or "no activity in N hours." They don't see location, messages, or anything personal. The senior's dignity is the whole design.
Know someone with parents on Android? Please share.
The hardest part of this stage is reaching the right people: adult children whose parents happen to be on Android. If a friend, coworker, or neighbor fits — please pass this along. It's how we reach the families who actually need it.
