Meet Jynth, the new synth by Fingerlab for iPhone, iPad and Mac — the warm, analog soul of the iconic Roland Juno-106, reimagined with a groundbreaking Physics Engine for organic, living sound. Designed for leads, basses, keys & pads, Jynth delivers that classic vintage character you love — housed in a meticulously crafted, photo-realistic interface that looks as good as it sounds. Shape your sound with a full analog-style signal chain: From the dual oscillators and resonant VCF filter to the ADSR envelope, LFO and built-in arpeggiator — every parameter has been carefully tuned to feel as musical as it sounds. Go further with 6 studio-grade effects: Tremolo, Flanger, Overdrive, Chorus, Delay & Reverb — stack them to build rich, evolving textures and cinematic soundscapes. Bring your presets to life with the Physics Engine: This is where Jynth truly stands apart. Assign up to 8 physics-driven modulations to any synth or effect parameter. Gravity, bounce, impulse, angle — let the laws of physics shape your sound in ways no LFO ever could. Every preset becomes unique, every performance feels alive. Explore new sonic territory with Preset Per Note & Preset Ribbon: Inspired by the music of Aphex Twin, Preset Per Note lets you assign a different preset to each key of the piano keyboard — so every note triggers an entirely different sound. Take it further with Preset Ribbon: select a collection of presets and glide between them in real time, simply by sliding your finger across the ribbon. A new way to perform. A new way to play. Play anywhere, plug into anything: Jynth is universal — one purchase gives you the full experience on iPhone, iPad and Mac. Use it as a standalone app or load it as an AudioUnit (AUv3) plugin directly inside your favorite DAW. Pair it with your MIDI controller via MIDI In support, and your sound is always there — even when your screen is off, thanks to Audio Background mode. Unlock the Full Version to access preset creation, all factory presets, FX, Physics Engine, Randomizer, Undo, Preset Per Note & Preset Ribbon.

s-2 is a polyphonic synthesizer designed to work with the Roland AIRA Compact S-1. ENGINE Each voice runs two parallel engine slots that mix together. Pick a sound flavor per slot, including: • Classic analog — saw, square, sub, noise, pulse-width • Wavetable • FM • Speech • Chord • Plucked string FILTER AND FX Classic mode runs a vintage-style ladder filter into a simple Delay → Chorus → Reverb chain. Modern mode swaps in a multi-mode SVF (LP / BP / HP) followed by a 3-slot Advanced FX rack with Bitcrusher, Drive, Flanger, Phaser, Auto-Filter, Tape Delay, Plate Reverb and Chorus. MODULATION Two free-routing LFOs (sine / triangle / saw / square / random / noise, with optional clock-sync), a dedicated filter envelope with two destination slots, and a unified mod matrix dialog that visualizes every routing in one place. Click any knob in Learn mode to assign — no digging through menus.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Jynth sells 1 one-off in-app purchase. S asks for nothing beyond the download.
S holds the better App Store score, 4.5 against 4.1. Both are backed by a comparable volume of ratings — 12 and 4 respectively. Written reviews complicate that: 71% of Jynth's written reviews are positive against 0% of S's, so the app with the better star average is not the one people write more warmly about.
Jynth ships an update every 2 weeks, S every 6 weeks. The most recent releases landed on October 10, 2026 and October 12, 2026 respectively.
