Designed to offer a tour of the sensors and features of LELO’s latest pleasure platform, F1s, this smart app should give you all the inspiration you need to start developing your very own sextech-compatible apps! This app connects via Bluetooth and allows you complete control over your F1s, showing just what’s possible with the SDK.

Your LELO F1s has a number of sensors and wireless controls built into it. This stylish app allows you to see all your statistics and use the product handsfree… or better yet, hand the controls to a partner for a new dimension of coupled play.
It’s the future of sextech!

App Function Possibilities:
• Control the vibration intensity of your F1s wirelessly
• Control the speed and power of your F1s
• Explore the vibration patterns and rhythms of your F1s
• Review the amount of pressure inside your F1s in real time
• Check the temperature of the device
• See the gyroscopic information
• See the usage counter and check your progress
• Find out more information about your F1s
• Review all relevant legal information

The sky’s the limit, and you can develop an app that uses this information to do anything your heart desires!

What’s New

Version 2.1.0

Dear users, here we are with the new version of Lelo F1S app. We added a simple space shooter game that you play using your F1S device. You have to tilt the F1S device right or left to move the spaceship and to make a stroke to fire. We hope you will enjoy it a lot. It is something new and exciting and expects further improvements in following releases.

Happy gaming!

Trial and error derived suggestions for connecting to and using the app

The lack of detailed documentation is very frustrating. I was able to increase the likelihood of connecting to the app and controlling the functions with the following steps :
1. Go to Settings and open up the Bluetooth connection window and leave it open in the background.
2. Turn off all unnecessary Bluetooth connections and apps(e.g. Tile)
3. Disable dark mode
4. Set display setting auto lock to never
5. Open the F1s app
6. Get to the connect window
7. Press the power button until the image rotates which should be about 5 seconds.
8. Choose play
9. Press the button icon at the bottom of the screen to turn on the ability to control both motors and counter function. Otherwise you can only control the vibration function with the buttons on the top of the device. And, there is no sonic function control outside of the app unless the bottom button icon is engaged.
10. You need to turn on the sonic motor with the bottom set of buttons.

Don’t buy the F1s V2. The app doesn’t connect, so you just spend $200 on a toy with no tech. Trash!

You’ll just be throwing money away if you buy the LELO F1s V2. I (and many others, just see the reviews) have had no luck getting the app to sync with the toy by following the instructions provided. Too bad I can’t give it zero stars.

Device looks cool. Feels cool when using it. The app is stylistic but basic. It really only lets you control the speed of two motors: sonic at the tip and basic vibration at the base of the shaft. The promise of app development is unfulfilled. The promised SDK has not been delivered. It’s really just a fancy, Bluetooth controlled sex toy. I expected more from LELO after the long wait and all the hype.
