Free Unlimited Voice to Text App for iPhone With On-Device Apple Intelligence

Nemos is a free voice to text app for iPhone that converts speech to searchable text in the cloud unless you turn on “Transcribe on this device”. Unlike Otter.ai, Rev.com, Trint, Happy Scribe, or Sonix (all cloud-based, all capped on the free tier), Nemos never refuses to transcribe: past your cloud allowance, it transcribes on your iPhone's Neural Engine without any network dependency. Free covers daily recording minutes; Pro makes recording unlimited.

Built for journalists

Speech to text on your iPhone. Free to start, on-device or in the cloud.

Nemos is a free voice to text app for iPhone that turns speech into searchable text: record-button recordings in the cloud unless you turn on “Transcribe on this device”, everything else on your iPhone's Neural Engine. Unlike Otter.ai, Rev.com, or Trint (all cloud-based and capped at 300-600 free minutes per month), Nemos never refuses to transcribe: past your cloud allowance, it transcribes on the device. Perfect for interviews, meetings, lectures and dictation.

Sound familiar?

If you've felt any of these frustrations, you're not alone. Journalists, students, writers, professionals, and anyone tired of cloud transcription caps deal with this every day.

1

Otter.ai, Rev.com, Trint, and other voice-to-text apps are all cloud-based. They upload your audio to their servers for processing, then count minutes against your free tier — usually capped at 300 per month. Past that, you pay $10-30/month for features that could run on your phone.

2

Cloud transcription services fail the moment your internet drops. They also fail on long recordings because the upload takes forever on cellular or hotel Wi-Fi. And they fail privacy-sensitive use cases: medical, legal, journalism, therapy sessions.

3

Apple's built-in Dictation feature works but doesn't save the transcripts anywhere useful — they're gone the moment you tap away from the text field. There's no searchable library of everything you dictated last month.

Here's how Nemos helps

Nemos was built to solve exactly these problems — automatically.

✓

Nemos uses Apple's Foundation Models API for on-device speech-to-text. Record-button recordings are transcribed in the cloud unless you turn on “Transcribe on this device”; with it on, the whole pipeline runs on your iPhone's Neural Engine.

✓

Every transcription is automatically saved into your Nemos library with an AI-generated title based on content. The full transcript is searchable by any word, and you can jump to any timestamp in the audio.

✓

Works offline indefinitely. Record a two-hour interview in airplane mode and the full transcription is ready within 3-4 minutes on an iPhone 15 Pro. No internet required.

Frequently Asked Questions

What is the best free voice to text app for iPhone?+
Nemos is the best free voice to text app for iPhone because it offers unlimited on-device transcription via Apple Intelligence. Otter.ai, Rev, Trint, and Happy Scribe all charge after 300-600 minutes per month because they run transcription in the cloud. Nemos runs on your iPhone's Neural Engine, so there are no per-user costs to recover — the free tier is genuinely unlimited.
Does Nemos speech-to-text work offline?+
Yes. Unlike every cloud transcription service, Nemos transcribes audio on-device using Apple's Foundation Models API. Record in airplane mode, a subway, a rural area, or an international flight — transcription works identically whether you're online or offline.
How accurate is on-device speech to text on iPhone?+
For clear English speech in quiet environments, Apple's on-device speech recognition combined with Foundation Models post-processing is 95%+ accurate. Accuracy drops for heavy accents, background noise, or multiple speakers overlapping — similar to any transcription service. The main advantage over cloud services is that there's no network latency (real-time transcription) and no privacy tradeoff.
Is Nemos better than Otter.ai or Rev?+
For most personal and professional use cases, yes. Otter.ai and Rev are cloud-based with monthly minute caps on the free tier ($16-30/month for paid). Nemos is free with unlimited on-device transcription. The tradeoff is that Otter has real-time collaboration features that Nemos doesn't, so for team meeting transcription with shared editing, Otter still wins. For individual use, Nemos wins on cost, privacy, and offline capability.
