HF-Memo is an easy-to-use mobile phone application for drivers, to handle voice and text data in the car. It is equipped with a Bluetooth remote controller for convenient access. Easily record parts of phone calls or your own dictation, or let your phone speak any incoming SMS, e-mails or WhatsApp messages aloud instead of reading them yourself, with just one press of a button!

  • Only two switches on the remote controller, it’s easy to use: record and play voice files or listen to SMS, e-mails or WhatsApp messages spoken aloud. It’s easy to use, with only two switches on the remote controller, preferably attached to the steering wheel with an extra accessory: shift between modes, record and play voice files or listen to SMS, e-mails or WhatsApp messages spoken aloud. 
  • Use HF-Memo with any wired or A2DP compatible bluetooth handsfree equipment to get the best out of it.
  • Your phone runs the application in the background. Since you operate it via the remote controller, using HF-Memo doesn’t interfere with your regular phone actions. Dial a phone number while hearing it from a recording!
  • The recordings are stored as normal audio files that can be sent as MMS messages or transferred to your computer. HF-Memo uses your phone’s internal memory or memory card for the recordings, so the recording capacity depends on the amount of memory installed to the phone.
  • The remote controller can be charged with your phone’s charger. No extra gear needed!
  • The application software comes on a standard 1 GB microSD memory card for easy installation on the phone.
  • Currently supported text-to-speech languages: languages: English, French, German, Italian, Spanish, Portuguese, Greek, Turkish, Polish, Dutch, Norwegian, Swedish, Finnish, Russian, Japanese and Mandarin Chinese.

Android compatibility:

This application is compatible from Android version 4.3 (Jelly Bean) and upward.

Recording parts of calls:
Note: Not all Android phones support the two-way call recording feature. If your phone only supports recording your own voice, just repeat what you’ve heard and you’ll also make sure you heard it right.


Bluetooth: pairing the phone and HF-Memo remote controller for the first time

  • Switch on the remote controller by pressing either of the two buttons. The blue led starts to blink.
  • Using your phone’s bluetooth control panel (typically under something like Settings > Wireless and Networks > Bluetooth), find the device “HF-Memo” and start pairing. See your phone’s user manual for further information about pairing bluetooth devices.
  • Once the phone discovers the HF-Memo controller, you are asked for a password. Enter “123456”. The pairing is ready.
  • We recommend that you use the phone’s bluetooth control panel to select automatic connections to the “HF-Memo” device.

Installing the application software

  • Insert the microSD memory card in your phone’s memory card slot.
  • The application asks for a license code. You’ll find your code attached to your sales package. You must also read and accept the usage terms.
  • In the beginning, your phone requests you to accept applications from unknown sources. After your approval, proceed as requested by the installation software. When the installation is complete, the HF-Memo icon appears on the phone’s applications list.
  • Start the HF-Memo application. Open the Settings menu and change the default settings where appropriate.
  • In order to use the text-to-speech feature, you must enter your e-mail address, password and incoming server of your mailbox in the appropriate fields and save them. Note: While typing, please check that “predictive text mode” is NOT ON.



  • To switch on the power, hold down either of the two buttons (REC or PLAY) until the led becomes active. If this takes time or you’ll see the text “unable to connect”, you can connect manually by opening the Settings menu and selecting “Connect a device” and then “HF-Memo”. 
  • The device is ready for use when the blinking of the blue led turns slow.
  • To switch off the power, hold down the REC button until the blue led stops blinking. The power is also automatically switched off when the bluetooth connection is cut off (distance between the phone and the controller is > 10 m).


You can use the remote controller in two different modes:

  • Text-to-speech mode: listen to your phone read your SMS, e-mails or WhatsApp messages aloud
  • Audio recording mode: record and listen to voice files

To enter text-to-speech mode, shift between modes by a long press of PLAY button or tap the mode icon. You’ll see the indicator of the mode available on the phone’s screen. 

Note: in order to enable listening to emails, you have to configure and save your email settings on the HF-Memo application Setting menu. If you use Gmail, you may be forced to lower your security level – please select the lower level of the two alternatives if needed, in order to use reading aloud your gmails. Google sends you a link to change it after trying to play your gmail at the first time. 


  • PLAY (yellow button)
  • To listen to recorded notes, or messages, click the PLAY button. You’ll hear the newest SMS message. To move to the second newest, see SKIP backward.
