Dialer for iPhone

What this app is for

Dialer is a no-cost iPhone utility from developer Emmanuel Tsouris that generates DTMF tones for dialing Plain Old Telephone System (POTS) lines and any other equipment that responds to touch‑tone sequences. It’s listed under Utilities & Tools and is intended to simplify calling scenarios that require sending sequences of tones (for example, calling-card access numbers or automated conference bridges).

Standout capabilities

• Insert commas to create pauses in the dialing string, handy for navigating prompts or timed menus.
• Save up to five quick-access entries in the free version so you can call frequent numbers or sequences with only a tap.
• Works not only with standard landlines but also with other devices and systems that accept DTMF for setup or control.
• Adjust the loudness of the generated tones using your iPhone’s hardware volume controls to match the target system.

Upgrade options (Dialer Pro)

• Remove the favorites limit and store as many dial sequences as you need.
• Modify the length of each tone and the duration of pauses to better match different systems’ timing requirements.
• Unlock the extended DTMF set (A, B, C, D) for specialized equipment that requires those tones.
• Access advanced customization for users who need more control over dialing behavior.

Alternatives and recommendations

• AppValley — free alternative marketplace offering a variety of apps and tweaks.

Quick start guide

• Download and install Dialer from the App Store.
• Create a favorite entry for any calling card number, conference line, or multi-step phone tree.
• Use commas to insert delays where the automated system expects input.
• Press the device volume keys to set an appropriate tone level before sending the sequence.

Final summary

Dialer streamlines sending DTMF tones from an iPhone, making repetitive or complex dialing tasks faster and less error‑prone. The free edition covers basic needs with up to five favorites and pause insertion, while the Pro upgrade is aimed at power users who require unlimited entries and finer control over tone and pause parameters.
