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 either: 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. 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).
Shower Thoughts Notetaker
Read full descriptionHide full description
Shower Thoughts is a push-to-talk voice notes app for the thoughts that arrive in the cracks between tasks — walking, driving, the moment before you forget. Hold a button, speak, release. The recording is transcribed entirely on your device and saved as a searchable note. The audio is deleted the instant the transcript lands. No account. No cloud. No network requests. Works in airplane mode. — On-device speech recognition. Powered by whisper.cpp, a tiny open-source speech model that runs on your iPhone's own silicon. Nothing about what you say is sent to a server. There is no server. — Audio deleted on success. The recording is treated as transient working data. The moment the transcript is committed to the local database, the audio file is removed from disk. If transcription fails, the audio is kept so you can retry — then deleted as soon as the retry succeeds. — Search every word. Full-text search across every transcript you've ever saved. Find the thought you had on Tuesday by typing two words from it. — Export when you need it. One tap produces a JSON file of every note and hands it to the iOS share sheet. Save it to Files, send it to yourself, drop it into another app — it's your data. — Built for thinking, not curation. No tags, no folders, no categories. Search is the only way back to a note, because curating is the work this app was designed to avoid. Privacy specifics: • No data ever leaves your device — there is no server to send it to • No analytics, no telemetry, no third-party SDKs collecting anything • Microphone access is used only while you are actively holding the record button • Open source: github.com/kilsekddd/shower-thoughts

Verdict
The clearest difference is in-app purchases: Shower Thoughts Notetaker at none against Möbius Sync's 1. Möbius Sync's advantage is iOS requirement (14.1 vs 16.0). On price, ads and device support there is nothing between them.
