Glow in the dark synthesis. Phosphor 3 is a dual-oscillator additive synthesizer that puts the raw building blocks of sound at your fingertips. Draw, randomize, or select up to 64 harmonics per oscillator, then shape them with envelopes, LFOs, cross-modulation, and a flexible mod matrix. Originally inspired by the alphaSyntauri, a rare digital additive synth from the early 1980s, Phosphor 3 takes that concept far beyond its origins with modern MPE expression, polyphonic modulation, and a full effects engine. --- Additive Oscillators Two identical additive oscillators, each with up to 64 individually editable harmonics. Start from classic shapes: sawtooth, triangle, square, or draw your own harmonic spectrum directly in the partial editor. The intelligent randomizer generates musically useful timbres with variable rolloff, density, and formant peaks, so every click produces something worth exploring. Choose 16, 32, or 64 partials per oscillator to balance complexity against CPU. Each oscillator has independent level, pan, transpose, fine tune, a noise generator with lo-fi downsampling, and cross-modulation (FM) for pushing timbres into harsher, more complex territory. Modulation Two ADSR envelopes with adjustable attack, decay, and release curves. Two LFOs with four waveforms (pulse, sine, saw, random), tempo sync, and the option to run polyphonically, a separate LFO per voice, or globally. An 8-source modulation matrix routes velocity, pressure, pitch bend, mod wheel, CC 74, triggered random, and both LFOs to destinations across the oscillators and effects. Effects Stereo delay with independent left/right time, feedback, and cross-channel feedback for ping-pong and rhythmic patterns. Tempo sync locks delay times to your DAW. Dual band-pass filters after the delay let you carve the wet signal into resonant, frequency-specific textures. Expression Full MPE support with per-note pitch bend, pressure, and slide across 16 polyphonic voices. Mono legato and mono retrigger modes with adjustable portamento. Unison mode for thick, detuned stacks. A scrollable 128-key on-screen keyboard with velocity from touch position, pitch bend from horizontal drag, and channel pressure from vertical drag, no hardware controller required. Tuning MTS-ESP client support for real-time microtuning from any MTS-ESP master. TUN file import for custom scales. Standard 12-TET with adjustable A4 reference. Supports AUv3 for use in GarageBand, AUM, Cubasis, and other AUv3-compatible hosts.

Verdict
The clearest difference is update cadence: Teraverse at every 4 weeks against Phosphor 3's every 11 months. Teraverse also leads on ratings volume (112 vs 9) and price ($2.99 vs $5.99). On rating, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Phosphor 3 costs $5.99 and Teraverse $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.7 for Phosphor 3 against 4.8 for Teraverse. That said, the two scores are not equally well evidenced: Teraverse has 112 ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 79% of Phosphor 3's written reviews are positive against 83% of Teraverse's.
Phosphor 3 ships an update every 11 months, Teraverse every 4 weeks. The most recent releases landed on July 6, 2026 and September 23, 2026 respectively.
