Kinu

Kinu is a personal relationship app for keeping track of friends and family. It best suits people who want help remembering personal details and reaching out, without a social feed or sales workflow. Its privacy-first approach is appealing, but the free plan’s 10-person cap and lack of cross-device sync set clear boundaries.

Overview

Kinu pairs personal records with gentle prompts: save notes, voice notes, moments, rituals and important dates for each person, then receive reminders when a date comes around or it has been a while since you were in touch. That combination gives users a place to preserve relationship context and a nudge to act on it. It is intentionally personal rather than a tool for sales contacts or building a larger social network.

There are no feeds, followers, likes or public profiles. Relationship data stays on the device by default, and voice notes are never uploaded on any plan. Users can enable free encrypted backup or paid encrypted sync; with either option, data is encrypted on the device before it leaves, then remains encrypted in transit and at rest. Kinu also works fully offline after sign-in, saves writes to the device first, and lets users export their data whenever they like.

Key features

Records and reminders

Notes, moments, rituals and dates keep personal context alongside each contact, while date and follow-up reminders help turn that context into timely outreach. This is a focused approach for people who want to be more intentional with a small circle; it is not a substitute for a broad contact-management or sales system.

Private, offline-capable use

Apple, Google, or email-and-password sign-in gets users into the app, after which core use works offline. Local storage by default and on-device voice notes make Kinu a strong fit for privacy-conscious users. Free encrypted backup adds a way to protect data without paying, but it does not provide cross-device sync.

Pricing

Kinu is freemium, with a free trial also offered. The free plan costs nothing, requires no card and has no time limit; it is a permanent plan, not a trial. It includes core features and free encrypted backup for up to 10 people, but no cross-device sync. That limit is workable for a deliberately small circle, but restrictive for anyone tracking a broader network.

Kinu Plus (monthly) costs $6.99 a month and adds unlimited people and encrypted sync across devices. Kinu Plus (yearly) costs $69.99 a year for the same features; it suits users committed to ongoing use who prefer annual billing. Both paid plans remove the contact cap and add sync, while the cheaper free plan gives up those two benefits.

Founding Member Lifetime costs $149.99, paid once. It includes everything in Plus, future updates and no renewals, making it the option for users who prefer a one-time payment over a recurring subscription. The listed plans differ most in contact capacity, sync and billing structure.

Platforms

Kinu is available on Android, iOS and the web. Offline use after sign-in is useful when connectivity is unreliable, while encrypted sync is the paid route for keeping use in step across devices.

Who it's for

Kinu fits people who want to remember meaningful details and follow up with friends and family, especially those who value local storage and want the option of encrypted backup. It is less suitable for someone who needs a free, multi-device setup, since free backup does not include sync, or for users managing more than 10 people without a paid plan. It is not aimed at sales teams or public social networking.

Pros and cons

• Pros: Relationship data stays local by default, with free encrypted backup and encrypted paid sync for people who want additional protection or multi-device access.
• Pros: Voice notes stay on the device on every plan, and offline use continues after sign-in.
• Pros: The permanent free plan includes core features for up to 10 people without requiring a card.
• Cons: The free plan has a 10-person cap and no cross-device sync, so larger circles or multi-device use require Plus.
• Cons: Kinu focuses on personal relationships, making it a poor fit for sales contact management or a public social network.

Alternatives

• Contacts+ Personal CRM is worth considering for users who want up to 1,000 contacts on its free plan and daily sync across web, iOS and Android.

Verdict

Kinu is a strong choice for individuals who want a private, offline-capable way to remember details and follow up with friends and family. Its defining advantage is keeping relationship records personal, with encrypted backup available free and sync available on Plus. Look elsewhere if you need more than 10 people without paying, free cross-device sync, or a system designed for sales contacts.
