Omi AI Review of the Open-Source Omi Pendant
What Omi costs and where its open-source design pays off, from Omi's published pages and app-store ratings.
Omi works well for developers who want an open audio recorder. It is a poor fit if you need guaranteed water resistance or multi-day battery life.
At Layer3Labs, we build AI workflow automation, custom agents, and intake integrations for small and mid-sized businesses. We work from each maker's published prices, plans, and technical documentation rather than hands-on hardware testing.
Verdict: Who Omi Is For
Omi is a good buy for technical users who want an open, hackable meeting recorder and can accept a short return window.
The device fits developers, engineers, and operators who want direct access to audio files, API keys, and device firmware. You can run self-hosted transcription or connect custom agents through webhooks. It is a poor choice for corporate buyers needing certified security controls or field teams needing rugged hardware.
On monthly billing, Omi Unlimited costs more than the $129 promo pendant after five months ($149.95) and more than the $179 list price after six months ($179.94). If 300 cloud minutes a month cover you, the pendant price is the whole cost, because on-phone transcription is free and unlimited.
Our verdict would change for enterprise teams if Omi completed an official SOC 2 Type II audit or published an ingress protection rating. Until then, business buyers should keep Omi to small pilots.

Hardware Architecture and Core Recording Mechanics
The Omi pendant is an audio-capture wearable made by Based Hardware, a San Francisco company founded by Nik Shevchenko.
The hardware first launched in July 2024 under the name Friend. Based Hardware renamed the product to Omi by October 2024 after Avi Schiffmann's unrelated Friend necklace claimed that name. The Android package name remains com.friend.ios as a legacy identifier from that transition, and our Friend necklace review explains the difference between the two products.
The physical pendant measures 2.5 cm by 1.5 cm and houses two microphones alongside nRF5340 and nRF7002 chips for wireless connectivity. It pairs over Bluetooth with the Omi mobile application on iOS 15 or newer and Android 7 or newer to stream audio straight to your phone. It can also record offline and sync files once the wireless connection restores.
You do not need to buy hardware to test the software ecosystem. The Omi mobile application and the desktop Mac app can record conversations using the built-in microphone on your phone or computer. Apple Watch recording is supported as well, letting you capture discussions directly from your wrist.
Omi's blog announced a $2M funding round led by Tim Draper in January 2025. Omi says it is trusted by 300,000+ professionals. That is Omi's own figure; the Android app shows 10K+ downloads on Google Play.
Hardware Pricing and Subscription Tiers
The Omi pendant carries a list price of $179, with an automatic $50 checkout discount reducing the current promotional price to $129.
Every package includes the wearable unit, a protective silicone case, a neck lanyard, a magnetic USB-C charging cable, and a quick start guide. Based Hardware sells a wrist band separately for $29.99, marked down from a $49.99 list price. You can also purchase an extra wireless charger for $29.99, though one magnetic cable already comes in the retail box. Developers can order the Omi Firmware Developer Kit for $59.99, which contains a J-Link debugger and a dedicated flash PCB.
Every pendant purchase includes a free plan that provides unlimited on-phone transcription and 300 cloud minutes each month. The paid Omi Unlimited tier costs $29.99 per month, or about $270 a year on annual billing. Upgrading to Unlimited adds real-time transcription, speaker identification, higher transcription quality, battery-optimized capture, and 1,000 monthly Ask Omi questions. An older August 2026 help article mentions a Plus plan at $19 a month for 1,500 listening minutes. It is not on Omi's pricing page, so check current plans in the Omi app under Settings → Plan & Usage.
Omi's enterprise page lists bulk discounts. Orders of 10 or more devices get 10% off, 100 or more get 20%, and 1,000 or more get 30%. Omi supports those bulk orders with a 7-day pilot requiring a refundable $89 deposit per unit. You can explore a complete cost comparison in our Omi pricing guide.
Hardware prices and subscription terms can change at any time, so confirm the latest rates on the Omi pricing page before placing an order.
Public Ratings and Owner Feedback
Public app marketplace ratings for Omi show middling satisfaction across both major mobile platforms.
On the App Store, the Omi application holds an average rating of 3.89 stars across 181 published ratings. The Google Play store listing reflects a score of 3.9 stars across 438 customer reviews and more than 10,000 total downloads.
The one specific complaint we found is a Google Play review from September 2026. It says the free plan allows only a few Ask Omi questions. Omi's pricing table shows no number for that cap, and Omi Unlimited raises it to 1,000 a month.
If you mainly want transcripts, the free plan covers that. If you plan to question your recordings every day, budget for Omi Unlimited's 1,000 questions a month.
Developer Ecosystem and Code Integrations
Omi's biggest strength is that its code and hardware designs are open source.
Based Hardware publishes the device firmware and application code under the MIT license on GitHub, where the repository has collected about 13,600 stars. Teams with infrastructure engineering resources can inspect the codebase, modify the firmware, or self-host the backend services using Google's cloud reference stack.
The ecosystem includes an in-app store that Omi says holds 1,000+ apps, along with native webhooks for audio bytes, live transcripts, memory creation, and automated day summaries. Developers can connect external tools through Zapier or query conversation history using Omi's hosted Model Context Protocol server. That server integrates with Claude, Claude Code, ChatGPT, Codex, and Cursor via OAuth or API tokens. Omi also provides a direct REST API for programmatically managing conversations and action items.
The Omi mobile application is not locked to Based Hardware devices. It can pair with third-party audio wearables such as the Plaud Note or NotePin, connect with Bee hardware, and import historical archives from Limitless.
In the law-firm intake and CRM work we do, webhooks and API access like Omi's let a team send transcripts straight into practice-management software without moving files by hand.
Operational Limits and Contested Specifications
Omi's own pages disagree on two specs, and several others are missing.
Battery runtime represents an immediate daily constraint. Omi's retail product pages state that the pendant operates for 10 to 14 hours on a single charge. Omi's GitHub README claims 24h+, and Omi's docs say battery life varies. You will need to charge the device every night if you wear it through a standard working day.
Several physical specifications remain unconfirmed. We could not verify the device weight, internal storage capacity, or full recharge time from published vendor documentation. Furthermore, we could not verify an official water resistance or ingress protection rating, and Based Hardware's refund policy explicitly excludes coverage for moisture damage.
Visual indicators are similarly limited. Omi's help center documents no dedicated recording light; the status light shows connection and charging. The light shows red when disconnected, orange while charging, and blue when connected to your mobile device. It buzzes during initial power-on. When the 300 cloud minutes run out, Omi keeps recording, and the audio is kept for export or later processing.
Omi's pages disagree on the return window. Omi's refund policy page states that change-of-mind returns must be requested within 5 days of delivery. That window extends to 14 days in the UK and European Union, and 15 days for damaged units. However, Omi's help center states a 3-day window, while a separate marketing page mentions a 30-day money-back guarantee. Prospective buyers should assume as little as 3 days to test the hardware and check the official Omi refund policy before ordering.
Data Retention and Legal Consent Compliance
Before you record clients with Omi, know where the audio goes and who must consent.
Omi stores customer conversation transcripts and raw audio files in Omi's cloud, hosted in the US, with vector embeddings managed in Pinecone. Data stays encrypted at rest using AES-256 and during transit via TLS protocols. Based Hardware states in its privacy policy that it does not use customer recordings or transcripts to train artificial intelligence models without explicit permission.
Transcription pipelines rely on third-party and self-hosted transcription models, though users can configure custom speech-to-text endpoints in the mobile application. Text analysis routes to OpenAI models using text data rather than raw audio streams. You can delete a conversation, with its transcript and audio, in the Omi app or by emailing help@omi.me. General technical questions and hardware support requests must go through the Omi help center.
Security credentials require careful scrutiny. Omi says it follows SOC 2 and HIPAA standards; its enterprise page says SOC 2 Type II is still in progress. Regulated firms handling patient health information or non-public financial records should not treat the device as a certified repository.
Omi says users are responsible for getting consent under local law. That matters because some US states require every participant's consent before a recording. We outline those state statutes in our all-party consent guide and discuss operational guidelines in our recording consent compliance overview.
Pendant Alternatives and Market Comparisons
Plaud, Fieldy and Bee sell rival pendants, and Limitless has stopped selling its Pendant.
Plaud sells the NotePin for $159, the NotePin S for $179, the Plaud Note for $159, and the Plaud Note Pro for $189. Its subscription options on the Plaud plan pricing page include a free Starter tier with 300 minutes. Paid tiers include Pro with 1,200 minutes at $99.99 annually or $17.99 monthly, and Unlimited at $239.99 annually or $29.99 monthly. Other Plaud specifications are not in our verified data, but you can read our Omi vs Plaud comparison to evaluate both options.
Fieldy, produced by Field Labs Inc., sells the Fieldy 3 for $129 on sale down from its standard $179 regular price. The company provides a free Basic tier with 150 minutes, and an Unlimited plan at $19.99 monthly or $15.99 monthly billed yearly. Fieldy offers a 14-day return window, a 1-year warranty, free worldwide shipping, and claims support for 100 or more languages. Other technical specifications for Fieldy are not in our verified data; see our Fieldy review for further analysis.
Bee offers the Bee Pioneer for $49.99, though the business was acquired by Amazon in July 2025. The device ships exclusively within the United States, works solely on iOS, and lists up to 7 days of battery life, 40 languages, and a visible green capture LED. Bee's current subscription pricing is not in our verified data.
Limitless stopped selling its Pendant on December 5, 2025, when it announced it had been acquired by Meta. Existing Limitless users retain service through 2026 on a free Unlimited plan, but prospective buyers can no longer purchase that hardware new. Finally, the Friend necklace costs $249 as an AI companion from Avi Schiffmann rather than a productivity note-taker, as outlined in our Omi alternatives guide.
How to Test Omi Before You Buy
You can evaluate Omi's transcription accuracy and mobile workflow without spending any money on hardware.
Download the free Omi application on your smartphone and create an account. Next, record a full week of internal meetings using your phone microphone per instructions in the Omi help center. This trial lets you inspect transcript formatting, test summary accuracy, and verify whether 300 cloud minutes a month covers your schedule.
Multiply that week by four: if the total stays under 300 cloud minutes, the free plan should cover the pendant too.
