YouLMK vs Bark

YouLMK or Bark?

Bark, in its own words: "an iOS App which allows you to push custom notifications to your iPhone": "free, simple, and secure, leveraging APNs without draining device battery", MIT-licensed, with a server you can host yourself and encrypted pushes (9,070 stars on GitHub on 12 September 2026). YouLMK is an inbox you let things interrupt you through: anything with an HTTP client sends into it, and you decide per sender how far a message may reach, whether quiet hours hold it and how repeats group. It can also watch a page, an endpoint, a status page, a feed, a number or a time, and send when the answer changes.

Every fact about Bark below was read on its own pages on 12 September 2026. If one has changed since, write to hello@youlmk.com and it is corrected the same day.

Side by side

Bark

YouLMK

What it is

An iOS app and a small server: call the server's URL with your device key and the phone gets the push.

A hosted inbox: every sender has its own key and its own rules on your side.

Price

Free; the app is free on the App Store and the server is open source.

Send $4 a month or $40 a year for unlimited notifications; Watch $12 or $120 adds watching. Trial: 10 notifications and 3 watches, no card.

Open source

Yes, MIT, the app and the server.

No. The libraries, the Claude Code plugin, the GitHub Action and the Apprise plugin are open source; the service is not.

Self-hosting

Yes, the server.

No, hosted only.

Platforms

iPhone.

iPhone and Apple Watch, Android, the browser, email, Slack, a signed webhook you own.

Sending

A GET or POST to the server with the device key, title and body in the URL or the body.

POST text or JSON to your key, GET with query parameters, a bearer token door, a webhook URL that understands 21 services, an MCP server, libraries for Node, Python, Swift, Kotlin and React Native.

Rules on the receiving side

The sender's parameters per message; the phone's own settings.

Per sender: a Reach level (Silent, Badge, Banner, Break through), whether quiet hours hold it, grouping of repeats within a window, which destinations it reaches.

Watching

None; Bark sends what it is given.

A sentence becomes a watch: a page, an endpoint, a status page, a feed, a number or a time, checked on a schedule.

Choose Bark if

You want a free push to an iPhone from a script and are happy to host the server, or to use the public one.
You need the code to be open, end to end.
One device, one key, and the phone's own settings are rules enough.

Choose YouLMK if

Several things send to you and they should not all be equally loud, decided once per sender.
You use Android too, or you want the same inbox in a browser, in email, in Slack or on a webhook of yours.
You want quiet hours that hold, repeats grouped into one card, and a watch on a page, a price or an endpoint without running anything.

What is the same

Both put a push on an iPhone from one HTTP call with the key in the URL, and both work with Apprise. Bark is the smallest possible version of that; YouLMK is for what happens after the push arrives, and for Android, email, Slack and webhooks.

Try it

The trial is 10 notifications and 3 watches, no card, no clock. Get your key, or read the docs first.
