Modulin is the world's most customizable synthesizer. It allows for unique personal expression while providing a wide spectrum of visual feedback. The playful colored strings are visually appealing while providing the user with fluent modulation of Modulin's LFO. The LFO replicates the vibrato effect heard throughout an orchestra or choir. The LFO can be set to four different wave types: Sinuous, Triangle, Sawtooth, and Square. It also can be set to a wide variety of frequency ranges. Modulin's oscillator can also be set to these four waveforms, but its pitch is controlled by the strings and a tuning knob. A simple low-pass filter allows you to cut off the unnecessary frequencies. The glide rate knob on Modulin creates a fluent portamento effect and allows for some pretty cool instrument replications. A slider located in the middle of the effects view can be dragged to reveal different effects and extra sound makers. Modulin includes reverb, delay, and chorus. It also contains a separate white noise module. Modulin simulates paraphonicness by allowing for a second VCO multiplied to form a gap of up to 2 octaves. Below all the knobs, an ADSR control allows you to manipulate the attack, decay, sustain, and release of your sounds. Modulin truly is the complete package for channeling your inner-composer. It can even record and store your works of art. A record button allows you to lay down a beat and overwrite it with complex melodies. The tracks button allows you to manage your tracks as you add them. New to synthesis? No problem. Modulin has an explore section that takes you through every component in an analog synthesizer, describing what it does alongside a diagram of how signals flow through it. Master of all things musical? Modulin's got you covered again. You can change the root note, octave, and type of scale that Modulin uses. If you feel really confident, you could even turn off the note names in the settings and try to memorize where everything is. With over 40 presets and other preset packages to buy, you will never run out of new and unique sounds. Even if you do, you can create your own and save it for later or share it with friends by the swipe of your finger. Fat fingers? Don't worry. With Modulin’s design, you can plug in an external MIDI keyboard and play it however you like. You can even map certain knobs on Modulin to knobs on your keyboard. It's magic! The more you explore Modulin, the more fun it becomes. You can personalize it by adding your own custom color or amp up the expression through the pressure sensitivity setting.

LH Grey is a groundbreaking synthesizer app that brings the lush, warm sounds of analog synthesis right to your fingertips. Designed for both beginners and seasoned professionals, this app offers a unique blend of classic and innovative features, ensuring an unparalleled sound experience. At the heart of LH Grey are two voltage-controlled oscillators (VCOs) that deliver the quintessential analog tone, rich in harmonic content and texture. These VCOs are the foundation of the app's sound, offering users the ability to create a wide range of tones from thick basses to ethereal leads. The filter section of LH Grey is a homage to the traditional, luxury analog synthesizers that have shaped the music industry. Featuring a range of classic filter types, it allows for deep experimentation and fine-tuning, enabling users to sculpt their sound with precision and warmth. Ease of use is at the core of LH Grey's design philosophy. The interface is clean and intuitive, making it easy for users to navigate and tweak settings to achieve the perfect sound. Whether you're a beginner learning the ropes or a professional tweaking your setup for a performance, LH Grey's user-friendly design ensures a smooth and enjoyable experience. However, it's essential to note that LH Grey does not support AudioBus-like features. This decision prioritizes a streamlined, focused approach to sound creation and manipulation, emphasizing direct interaction with its analog-styled components. LH Grey also comes packed with several high-quality effects that emphasize the analog character of the sound. With unison, chorus, reverb, and delay, users can add depth, space, and movement to their sounds, creating lush landscapes and rich textures that breathe life into their music.

Verdict
The clearest difference is rating: LH Grey at 5.0 against Modulin's 4.3. LH Grey also leads on in-app purchases (none vs 1). Modulin's advantage is ratings volume (17 vs 2) and iOS requirement (10.0 vs 13.0). On price, review sentiment, ads and device support 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
Both are free to download. Modulin sells 1 one-off in-app purchase. LH Grey asks for nothing beyond the download.
LH Grey holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Modulin has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 69% of Modulin's written reviews are positive against 67% of LH Grey's, so the app with the better star average is not the one people write more warmly about.
