KEY FEATURES: • Unlimited transcription for audio and video in 99 languages • Transcribe voice notes, real-time audio, and video/audio files • AI summaries and chat • Organize recordings in collections • Search transcripts • Copy and share transcripts (TXT, PDF, MD, DOCX, SRT) • Export recordings • Widgets and shortcuts PRIVACY: • We do not collect any user data. Both transcription and AI features run 100% locally, so your data never has to leave your device FAQ: What is the longest transcription supported? We support regular transcription of voice notes, audio files, and video files up to 8 hours long. We support live transcription up to 2 hours long. You can transcribe as many recordings as you would like. Is the app actually fully local? Yes! The app uses local transcription and LLM models, so all transcription and AI features work on-device. A network connection is only required once to download each transcription or AI model. Your data never leaves your device unless you choose to share it. We provide optional iCloud sync to back up your data and sync data between devices. If you have this disabled, your transcriptions will be deleted if you delete the application. We recommend backing up important transcriptions. Why do I have to keep the app open while it is transcribing? The app has to be open during transcription as iOS limits apps from operating in the background for extended amounts of time. If you are unable to run the app at the moment, you can quit and reopen the app at any time. The interrupted recording will automatically start transcribing again.

Verdict
The clearest difference is in-app purchases: OneLLM at none against Speech to Text's 2. Speech to Text's advantage is review sentiment (77% vs 56%) and update cadence (weekly vs fortnightly). On price, rating, ratings volume and ads 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. Speech to Text sells 2 in-app purchases, starting at $3.99 per month. OneLLM asks for nothing beyond the download.
OneLLM holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 26 and 32 respectively. Written reviews complicate that: 56% of OneLLM's written reviews are positive against 77% of Speech to Text's, so the app with the better star average is not the one people write more warmly about.
OneLLM ships an update fortnightly, Speech to Text weekly. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
