Hear a solo you want to learn, but you have no audio file to import? Hold your iPhone to the speaker, record it, and practise it slowly. - Record from a speaker with one tap - Automatic mastering evens out the sound of a phone recording and reduces hiss between notes - High-quality slow-down from 50 % to 100 % without changing the pitch - Repeat a phrase: set Start and End, drag the markers on the waveform, fine-tune by 10 ms - Speed and loop are remembered for every recording - Keeps playing with the screen locked; play/pause from the lock screen and AirPods - Share the slowed-down audio - Everything happens on your iPhone. No account, no ads, nothing is uploaded. Only record audio you have the right to use for your own practice.

See your stereo field. Vectorscope 2 shows the shape of a stereo signal as you hear it: how wide it is, where it leans and whether its channels work together or cancel each other out. Rebuilt from the ground up, it runs as an Audio Unit (AUv3) inside GarageBand, AUM, Logic Pro and any other host, and on its own with your device's microphone or an audio interface. TWO VIEWS OF THE SAME SOUND • X/Y: the classic Lissajous display. Mono sits on the vertical axis, wide material spreads across the diamond, and a signal out of phase turns sideways. • Polar: the half-disc view, with left, center and right laid out as you'd place them in a mix. • Short or long trail, automatic or fixed zoom, and four trace colors. METERS THAT TELL THE REST • Correlation, from +1 (mono-compatible) to −1 (out of phase), so you catch phase problems before they reach a mono speaker. • Balance, so you know where the energy sits between left and right. • Peak and RMS level meters with held peaks and clip indicators. Tap to reset. • A notice when the input is mono, so a single vertical line never looks like a broken meter. MADE FOR EVERY SCREEN Vectorscope 2 lays itself out for the space it's given: an iPhone upright or sideways, an iPad, iPhone Duo folded or open, and a plugin slot in a host, from GarageBand's compact strip to its expanded view. QUIET BY DEFAULT On its own, the app starts with its output muted, so the microphone never feeds back through the speaker next to it. As a plugin it passes your audio through untouched.

Verdict
SlowSolo and Vectorscope 2 are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
