This app generates Dual tone multi-frequency (DTMF) tones. These tones are used to interact with traditional landline phone systems, automated menus, and other devices that accept DTMF input. You can play the tones by holding your device's speaker near a phone's microphone or handset.
The app allows you to generate DTMF tones, save up to five favorite sequences in the free version, and adjust the volume. The paid 'Pro' version unlocks unlimited favorites, expanded DTMF tones (A, B, C, D), and the ability to customize tone and pause lengths for more precise dialing.
The app is free to download and use with basic features, including saving up to five favorite tone sequences. An optional in-app purchase is available to unlock 'Dialer Pro' features, such as unlimited favorites and advanced customization options for tone and pause lengths.
The app notes that some Voice over IP (VoIP) systems may have trouble recognizing the tones. For these systems, it's recommended to try a longer key press to allow sufficient time for the system to register the tone. The app is primarily designed for traditional POTS landline systems.
Common use cases include navigating complex phone trees, accessing teleconference numbers, making calls with calling cards that require tone input, and configuring other devices that utilize DTMF tones for setup or operation.
