lfoch vs Sonidata
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
lfoch
This app generates complex LFO waveforms with multiple outputs for creating "chase" effects. It offers two LFO generators with phase modulation, adjustable suboscillators, and waveform morphing. It can output MIDI control change values and sync to tempo.
- Dual LFO generators with phase/ring modulation
- Suboscillator modulation with waveform morphing
- Adjustable waveform rate, type, and range
- Output 1-16 MIDI control change values
- Tempo synchronization and AUv3 MIDI Effect support
- Two modes: 'perform' and 'edit'
- Randomize parameter values

lfoch is an experimental LFO generator that can create "chase"-like effect with multiple outputs from a single complex waveform It features: - 2 LFO generators with phase modulation / ring modulation: - Each LFO generators contains 2 suboscillators; one suboscillator modulates phase of another - For each suboscillator you can set waveform rate, waveform type (with smooth morph between sine, triangle, sawtooth and square waveforms), nonlinear curve (for overdrive-like effect) and minimum/maximum range - The result waveform is a multiplication of two generated LFO waveforms - You can use 1..16 points from this waveform to output as MIDI control change values - You can toggle the "playback" (phase change) of each generator with I/II buttons - You can randomise parameter values with "dice" buttons - App has two modes for live usage - 'perform' mode has larger waveform view and some selected sliders (if any) - 'edit' mode contains all controls on one screen - Each generator can be synchronized to tempo. In this mode the "speed" value runs from 4 quarter forward to 4 quarter backwards speed, the fastest value in this mode is 1/32 - When running inside AUv3 host the app uses host's transport. - "free mode" setting allows you not to follow the host transport lfoch is a standalone app and an AUv3 MIDI Effect. AUv3 effect supports parameter automation and preset saving inside host. Standalone version currently does not output MIDI in background mode.Note for AUM users:This application starts with 16 control change outputs from CC 0 to 15 on MIDI channel 1. AUM has default mapping of the CC #7 (volume) for each channel. Please keep this in mind when setting it up together.

Sonidata: UCS Field Recorder is built to help you maintain a professional audio archive on the go. Ensure every sound you capture is perfectly tagged, organized, and ready for high-level indexing the moment you get back to the studio. Designed for sound designers, field recordists, and audio professionals who demand precision from their mobile workflow. PROFESSIONAL CAPTURE & ROUTING Turn your device into a professional field recorder. With the newly introduced Audio Device Manager, select discrete input and output routing, apply hardware-aware format settings (48 khz 24 bit internally, and up to 192 kHz / 32-bit float, depending on the connected devices), and control input gain digitally or via your hardware interface. Monitor audio levels with the Record Ready monitor mode. Capture True Stereo or decode M/S microphones on the fly with per-mic persistence. UCS METADATA ON THE GO Say goodbye to renaming files back at the studio. Sonidata implements the industry-standard Universal Category System (UCS v8.2). Assign Category, FX Name, Vendor, Creator, Mic Perspective, Location, and more right from the field. Use the Voice Slate (Speech-to-Text) to dictate metadata hands-free, or create custom FX Name Templates to speed up repetitive tagging. POWERFUL BATCH EDITING & SYNC Manage massive recording sessions with ease. The new Calendar Filter Bar lets you drill down by date, while batch delete and bulk metadata pasting streamline your workflow. When you’re ready, your sessions—including embedded artwork and metadata—seamlessly sync to iCloud Drive, Google Drive, or Dropbox. SEAMLESS DESKTOP INTEGRATION Export comprehensive 29-column CSV reports fully compatible with industry-standard sound library management software. Use the companion desktop app, Sonidata Embed, to batch edit metadata and re-embed it into your WAV files without transcoding. KEY FEATURES • Broadcast-Standard Recording: 48 kHz 24-bit internally, anduUp to 192 kHz / 32-bit float WAV. • UCS v8.2 Compliant: Full metadata tagging (Category, FxName, Description, Mic Perspective, etc.). • Advanced Audio Routing: Discrete input/output selection, external interface support, and M/S decoding. • Visual Feedback: Live waveform-style stereo metering, colorized waveforms, and ActivityKit lock-screen tracking. • Cloud Sync: Automatic syncing via iCloud, Google Drive, and Dropbox. • External File Management: Import, edit, and organize audio recorded on other devices. • Seamless Export: ZIP exports grouped by date, paired with rich 29-column metadata CSVs. • Siri & Shortcuts Integration: Control recording hands-free via App Intents, Action Button, or Back Tap. • Secure & Private: All transcription and processing happen on-device. Your audio never leaves your device unless you export it. UPGRADE TO PRO Unlock the full potential of your field recording workflow with Sonidata Pro. Manage external files, create custom FX Name Presets, export in bulk, and unlock the Sonidata Embed desktop companion app for seamless macOS integration via secure offline pairing.

Verdict
The clearest difference is review sentiment: Sonidata at 100% against lfoch's 50%. Sonidata also leads on price (Free vs $3.99) and update cadence (every 3 days vs every 20 months). lfoch's advantage is in-app purchases (none vs 1) and rating (4.4 vs 4.0). On ads, device support and iOS requirement there is nothing between them.

Sonidata is free to download; lfoch costs $3.99 up front. Sonidata sells 1 one-off in-app purchase. lfoch asks for nothing beyond the download.
lfoch holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: lfoch has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of lfoch's written reviews are positive against 100% of Sonidata's, so the app with the better star average is not the one people write more warmly about.
lfoch ships an update every 20 months, Sonidata every 3 days. The most recent releases landed on September 28, 2026 and October 9, 2026 respectively.
