Self is the privacy-first way to prove you're human and verify who you are online (or give your agent a secure identity), without handing over your personal data. Trusted by Google, Opera, and 15M+ users. Verify your real-world identity once using a biometric passport, biometric national ID cards, Aadhaar, or any other supported identity document. Once registered, you can prove the specific attributes services require, such as your humanity, age, or nationality, without ever disclosing the underlying document or your personal information. Key Features: PROOF OF HUMAN: Prove you're a real person rather than an automated or duplicate account. AGE VERIFICATION: Confirm you're over 18 (or any age threshold) without revealing your birthday. Built for social apps, marketplaces, and age-gated services. PRE-KYC: Verify your eligibility (age, country of residence, sanctions, etc.) before any KYC process, only sharing your personal information with companies and institutions once necessary. AGENT ID: Delegate your identity credentials to your autonomous agent, unlocking broader utility and access across the internet. PRIVACY BY DESIGN: Self is using the latest zero-knowledge technology, fully audited by the world’s best security experts. All data is stored locally on the user’s device — never on any servers. When a user verifies their identity, a verifiable credential is created and saved securely in the app. There’s no cloud storage, no centralized database, and no way for anyone - including Self - to access the data without the user's consent. "We’re committed to ensuring developers can build faster with reduced friction while maintaining industry‑leading security standards," said Rich Widmann, Google. "Integrating Self allows us to further this mission with frontier zero‑knowledge solutions." Why Self Defend against bots and duplicate identities Meet age and compliance requirements without surrendering personal information Carry one verified identity across the apps you use, instead of re-uploading documents at every sign-up Help establish a global standard for verified identity that keeps people, not platforms, in control of their data

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. Neither carries in-app purchases, so what you see is what you pay.
Zingo! holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 9 and 25 respectively. Written reviews complicate that: 50% of Zingo!'s written reviews are positive against 75% of Self's, so the app with the better star average is not the one people write more warmly about.
Zingo! ships an update every 2 weeks, Self every 11 days. The most recent releases landed on October 24, 2026 and October 19, 2026 respectively.
