One2One help

1. Getting started

Install One2One from the App Store or Google Play, or open one2one.hollybyte.com in a browser. There is no registration: the first screen already offers to start a call, join one, or find a random partner.

The first launch asks for camera and microphone access. Both are needed for a video call; without them the app can only show you the other side.

2. Calling someone you know

• Tap Start 1-on-1 — the app creates a room and gives you a link and a short room ID.
• Send the link through any messenger. Your guest opens it and lands straight in the call, in the app if it is installed or in the browser if not.
• A room holds exactly two people. When the second one joins, the call starts.

Joining is always free — the person you invite never needs a subscription and never sees a paywall.

3. Random Match

Random Match connects you with another person who is looking for a call at that moment. While no one is available you will see a waiting animation instead of an empty screen. Skip to look for someone else. Free users get a few matches per day; Pro removes the limit.

4. One2One Pro

What it unlocks

• creating rooms and invite links without limits;
• scheduling a call and adding it to a calendar;
• Random Match with no daily limit;
• calls up to 4 hours instead of 20 minutes;
• turning your partner's camera and microphone on or off during a call.

Every new installation starts with a free week of everything. New yearly subscribers also get a 7-day free trial before the first charge.

Restoring a purchase on a new device

Sign in to the same store account you bought the subscription with, open One2One, tap the Pro pill on the welcome screen and choose Restore purchases. The same button is at the bottom of the subscription sheet.

Managing or cancelling

Subscriptions are managed by the store, not by us:

• iPhone / iPad: Settings → your name → Subscriptions → One2One.
• Android: Google Play → profile picture → Payments & subscriptions → Subscriptions → One2One.

Or tap the Pro active pill in the app and choose Manage subscription — it opens the right page for you. Cancel at least 24 hours before the period ends to avoid the next charge; Pro keeps working until the end of the period you already paid for. Refunds are handled by Apple and Google under their own policies.

The purchase did not go through

If the sheet shows "Store unavailable" and no buttons, the device could not reach the store — check the connection and try again. If money left your account but Pro is not active, open the app, tap the Pro pill and use Restore purchases; if that does not help, write to us with the store receipt.

5. When something does not work

The call does not connect

One2One connects two devices directly. Strict corporate, university or some mobile networks block that; the app then falls back to a relay server, which needs UDP traffic to pass. If a call never connects on one particular network, try mobile data or another Wi-Fi to confirm it is the network.

No video or no sound

• Check that camera and microphone permission is granted to One2One in system settings — on iOS, Settings → One2One; on Android, Settings → Apps → One2One → Permissions.
• Another app already using the camera (a different call, the camera app) can hold it. Close it and reopen One2One.
• In the browser, check the camera icon in the address bar and that the site is allowed to use the camera and microphone.

Poor quality or freezing

Video quality follows the weaker of the two connections. Move closer to the router, switch off other downloads, or turn your camera off for a moment — audio recovers first.

The call ended at 20 minutes

That is the free call limit. The app warns a couple of minutes in advance. One2One Pro raises it to 4 hours; when one participant has Pro, the whole call gets the longer limit.

6. Contact us

Anything else — write to one2one@hollybyte.com. Tell us the platform (iOS, Android or browser), the app version and roughly when the problem happened; it makes finding it in the logs realistic.
