How to connect Lelo F2S to funscripts

Connect toy in Chrome or Edge (built-in engine, nothing to install)

1. Open haptiq.app in Chrome or Edge on a computer or Android phone (or use the HaptiQ Android app from haptiq.app/android), sign in, and open Devices.
2. Switch the Lelo F2S on and close the maker’s app, so the toy is free to pair.
3. Press Connect toy and pick the toy in the browser’s Bluetooth list. The Buttplug engine is built into HaptiQ, so there is no Intiface Central and no download.
4. Load a funscript or generate one from a video and press play. If anything fails, Device Doctor checks Bluetooth, permissions and sync for you.

On iPhone or iPad, browsers block Bluetooth: use the free Bluefy browser today, or the HaptiQ iPhone app launching in October. Full Lelo F2S setup and troubleshooting guide.

Frequently asked questions

Does the Lelo F2S work with funscripts?

Yes. A funscript is a device-agnostic motion file, so the same script plays on any supported hardware. HaptiQ converts the motion in a video into a funscript and streams it to your Lelo F2S in time with playback.

How does the Lelo F2S connect to HaptiQ?

The Lelo F2S connects over Bluetooth Low Energy, directly from your browser using the Web Bluetooth API. That works in Chrome, Edge, Opera and other Chromium browsers on desktop and Android. Safari and Firefox do not implement Web Bluetooth, so use a Chromium browser. No extra software is required — no Intiface, no desktop app.

Do I need Intiface or Buttplug.io for the Lelo F2S?

No. The Lelo F2S pairs straight from the browser, so you do not need Intiface Central or any desktop software. HaptiQ also supports Buttplug.io if you prefer to route through Intiface.

Which browsers support the Lelo F2S?

Use Chrome, Edge, Opera or another Chromium browser, on desktop or Android. Safari and Firefox do not support Web Bluetooth.

Can I generate a funscript for the Lelo F2S from my own video?

Yes. Upload a video or paste a link, and HaptiQ's motion analysis produces a .funscript you can play on the Lelo F2S or export for another player. Large files are uploaded in parts, so multi-gigabyte VR video is supported.

What kind of device is the Lelo F2S?

The Lelo F2S is an onahole. HaptiQ maps the vertical motion in a funscript onto whatever actuation the onahole provides, so scripts written for other hardware still play.
