Möbius Sync brings Syncthing to your iPhone or iPad, allowing you to synchronize selected files between iOS devices and other devices supported by Syncthing, without the need for any cloud service. Supports multiple folders and multiple remote devices. Synchronized folders can be created: 1. in the Möbius Sync sandbox and files can be added to and retrieved from shared folders via the iOS Files app; or 2. (PAID feature) by accessing other apps' sandboxes. This feature is EXPERIMENTAL and may break other app's functionality; or 3. (PAID featured) iOS Photo Library folders can be exported to other devices send-only. Uses the open-source Syncthing engine internally. Usage within the Möbius Sync sandbox is free up to 20MB. Unlimited file sync, including files in other apps' sanboxes is available for a one-time purchase. NOTE: The functionality unlocked by in-app purchase is identical to that in Möbius Sync Pro (which is purchased up-front).
VoxDrop

VoxDrop is a focused voice-capture utility. Record a short clip, have a speech-to-text service you configure turn it into text, and optionally send the result to your own workflow through an HTTPS webhook. Why VoxDrop: • Bring your own credentials and service — use Alibaba Cloud Qwen3-ASR, Volcengine speech recognition, or a fully user-configured Custom STT HTTPS endpoint. Service availability may vary by App Store storefront. • Explicit data permission — before transcription or webhook delivery is enabled, VoxDrop lists the exact data and destination domain. Nothing is sent without your affirmative permission. • Automatic background workflow — once a recording ends, transcription and delivery continue without blocking your next recording. • Clear per-recording status — transcription and webhook delivery have independent progress and error states, with manual retry when needed. • Document-based hotwords — select a JSON terms file from Files; VoxDrop reloads its latest version whenever the app launches. • Recording-friendly behavior — the display stays awake while recording, and optional retention rules can remove older local recordings automatically. • HTTPS required — transcription and webhook destinations must use encrypted HTTPS connections. No VoxDrop account, no ads, and no developer-operated backend. Credentials remain in the on-device iOS Keychain.

Verdict
The clearest difference is in-app purchases: VoxDrop at none against Möbius Sync's 1. Möbius Sync's advantage is iOS requirement (15.0 vs 18.0). On price, ads and device support there is nothing between them.
