PhoneAmp is a tool that transforms your iPhone into an amplifier with a range of common effects. With this app, you can enhance your music experience by using features such as a 10-band equalizer, reverb filter with over 10 different presets, delay filter, and distortion filter with more than 20 presets. Additionally, you can record your music and share it with your own preset effects.

One of the key advantages of PhoneAmp is its versatility. You can play and listen to acoustic instruments like the guitar, ukulele, and violin, simply by using your headphone or headset and the built-in microphone on your iPhone. However, if you wish to connect an external instrument or microphone to your iPhone, you will need to purchase one of the available connection adapters on the market.

It is important to note that the sound quality may vary depending on the iPhone model, microphone, and headphone you are using. For the best performance, wired headphones or headsets are recommended, as using Airpods or other Bluetooth devices may result in latency issues.

The free version of PhoneAmp allows for 10 minutes of usage per hour and up to 40 seconds of recording time. However, you have the option to remove these limitations permanently with a one-time purchase. It is worth mentioning that this purchase is not a subscription and does not renew periodically.
