A 2026 comparison — EthOS's mobile ethnography app vs Yazi's WhatsApp-native research platform.
EthOS is an app-based mobile ethnography platform — respondents install the EthOS app and capture daily experiences via photo, video, text and voice over the study period. Yazi is the WhatsApp-native alternative: same mixed-method capture, no app install, pricing published per project.
- EthOS requires respondents to install an iOS/Android app; Yazi runs inside WhatsApp.
- EthOS has a broad global panel (3M+ across 150+ countries) but app-install friction still hurts completion in emerging markets.
- EthOS includes generative AI for analysis; Yazi's AI is tuned to voice and WhatsApp open text.
- For WhatsApp-first markets, Yazi is faster to launch, higher-completing and typically cheaper than EthOS.

Install vs no-install
EthOS and Yazi both run mixed-method diary studies with voice, video, image and text — one inside its own app, the other inside WhatsApp.
Yazi — WhatsApp, no install
- Tap a link, start contributing
- Voice / text / images / video / choice
- AI transcription, translation, sentiment
- Completion rates of 60%+ in most markets
EthOS — dedicated app
- Install iOS/Android app, sign up, accept project
- Photo / video / voice / text captures
- Generative AI analysis built in
- Works best with tech-comfortable panels
EthOS's researcher dashboard: UK-built mobile ethnography with AI analysis. Excellent for tech-comfortable US/UK/EU panels — less suited to markets where app-install friction is the real constraint.
Pros and cons — Yazi vs EthOS
Yazi's WhatsApp-native model removes app-install friction, published pricing removes quote cycles, and local incentive rails remove the "how do we pay respondents in Lagos?" problem. For mobile diary studies in WhatsApp-first markets, it's the dominant model in 2026.
EthOS is a strong choice for mobile ethnography in mature markets — especially UX research where the in-app capture experience and 3M+ global panel add real value. Generative AI analysis is built in.
Who is Yazi best for? Who is EthOS best for?
Yazi is best for
Brand-side researchers and agencies running diary, ethnography and mixed-method qualitative research in WhatsApp-first markets — Africa, LatAm, South and South-East Asia.
EthOS is best for
UX research teams and global insights programmes running mobile ethnography in the US/UK/EU, with tech-comfortable panels happy to install a dedicated research app.
How to switch from EthOS to Yazi
A four-step migration path for teams who've decided to move their programme across.
- Audit which EthOS studies are channel-agnostic
Most consumer-diary and mixed-method work is; deeply in-app UX-specific studies often aren't.
- Pilot one diary on Yazi
Run a 7–10 day WhatsApp-native diary parallel to a comparable EthOS study. Compare completion rate, media depth and cost.
- Move emerging-market fieldwork to Yazi first
The channel advantage is clearest where app-install friction is highest.
- Keep EthOS for specific UX ethnography
In-app UX research where screen recording, app-usage capture and tech-comfortable panels matter remain EthOS's stronghold.

FAQ — Yazi vs EthOS
The questions people actually search for when comparing EthOS to alternatives.
What is EthOS?
EthOS is a mobile ethnography platform — respondents install an iOS/Android app and capture their daily experiences via photo, video, voice and text over the course of a study.
How much does EthOS cost?
EthOS doesn't publish prices. DIY project access is typically in the mid-four-to-five-figure range per engagement, with managed services scaling higher.
Is there a cheaper alternative to EthOS?
Yes — for consumer diary studies and mobile ethnography in WhatsApp-first markets, Yazi runs the same scope at 55–75% less by removing the app install and distributing on WhatsApp.
Can Yazi replace EthOS for mobile ethnography?
For most consumer diary and mixed-method work, yes — Yazi captures the same voice, video, image and text data. For in-app UX ethnography with screen-recording requirements in mature markets, EthOS remains closer to the job.
How does Yazi compare to EthOS on AI?
Both include AI analysis. EthOS's generative AI is broader across capture types; Yazi's is tuned specifically to voice-note transcription, multi-language open text and WhatsApp sentiment — the places consumer research in emerging markets generates the richest data.
The bottom line
EthOS is a strong mobile ethnography platform for US/UK/EU panels comfortable installing a research app. Yazi is the WhatsApp-native alternative for everywhere else — faster to launch, higher-completing, published pricing and a dramatically lower cost for a comparable diary study.
