PRACTICE SMARTER. PLAY WITH BETTER TIME. Metronome Plus was created by a musician and educator for the way musicians actually practice. A metronome can tell you where the beat is. A great practice tool should help you develop better time, master difficult passages, and eventually need the metronome less. PRACTICE WITH A PURPOSE Slow difficult music down to where you can play it correctly, then gradually build toward your goal tempo. Instead of simply repeating a passage and hoping it gets better, turn it into a series of achievable steps. Accuracy first. Speed follows. BUILD TIME YOU CAN TAKE ONSTAGE Following a click isn’t the goal. Developing a reliable internal pulse is. Use Metronome Plus to recognize where you rush or drag, strengthen rhythmic consistency, and become more confident maintaining the pulse on your own. MAKE THE METRONOME FIT THE MUSIC A scale, orchestral excerpt, jazz chart, technical exercise, and ensemble part don’t necessarily need the same kind of click. Metronome Plus gives you the flexibility to shape the beat around what you’re practicing and the problem you’re trying to solve. FOR MUSICIANS AT EVERY LEVEL From students developing their first sense of steady time to experienced musicians preparing for tonight’s performance, Metronome Plus is designed to stay useful as your musicianship grows. Practice time is valuable. Spend less of it mindlessly repeating and more of it actually improving. METRONOME PLUS Practice with purpose. Play with confidence.

PaSSBot is a unique stochastic filter bank audio processor. The desktop VST/AU version of PaSSbot has already arrived in February 2020 and this iOS version is equivalent to the latest version 2.1. PaSSBot filter types are Biquad, StateVariableFilter, Ladder, SEM and Resonators. With behaviors of bandpass, Lo + Hipass, Notch and up to 64 of them in true stereo ! The user can set values of center frequency, gain and resonance of the each filter, which will be then eloborated with powerful stochastic generators ( 4 independent GENs for each filter ) with continuous or discrete probabilistic distributions but also with standard waveforms. One can set each filter parameters individually, but also distribute them in harmonic order, again the harmonic spread ratio can be set by the user or even can be modulated by a GEN. Precision DSP rendering, less than 1milisec. control rate precision. The filters can run continuously or be triggered manually. In that case, each filter will be applied an independent AR envelope with configurable random duration. Important notes : - A recent iPAD model is being recommended and also setting the host buffer size to 128 or higher greatly helps to the CPU needs which also heavily depends on the number of parallel filters being used. - The resonators can be sensitive to input signal level. - The PaSSBot manual can be found at this link. https://www.sonic-lab.com/PaSSBot_files/PassBot_manual.pdf sonicLAB PaSSBot youtube playlist : https://www.youtube.com/playlist?list=PLP0cOkraQHDYUoMG6BETTN1eGm-Kq5z0T

Verdict
The clearest difference is price: Metronome at $1.99 against PaSSBot's $34.99. Metronome also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (48 vs 8). PaSSBot's advantage is rating (5.0 vs 4.5) and review sentiment (100% vs 85%). On ads, in-app purchases, monetization model and device support there is nothing between them.

Metronome costs $1.99 and PaSSBot $34.99 up front. Neither carries in-app purchases, so what you see is what you pay.
PaSSBot holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Metronome has 48 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 85% of Metronome's written reviews are positive against 100% of PaSSBot's.
Metronome ships an update every 2 weeks, PaSSBot every 4 months. The most recent releases landed on September 30, 2026 and September 18, 2026 respectively.
