Frequently asked questions

Kelra is an MCP tool that gives AI agents precise iOS UI measurements and comparisons. Your agent measures a reference screenshot, builds the screen in SwiftUI, compares the result with the reference and fixes what differs. It is for iOS apps only.

The planned prices are $19.99 per month or $129.99 per year (about 46% less than paying monthly) for one account, which includes up to three of your own computers. Paid access is not open yet. The pricing page shows where things stand.

No. Payments are final and are not refunded, including for a billing period (a month or a year) you have already started and for the time left after you cancel. You keep access until the end of the period you paid for. This does not limit any refund or cancellation rights the law gives you where you live. The full wording is in the terms.

Yes. Once paid access opens, your subscription renews every month or every year, depending on the plan you choose, until you cancel, and your payment method is charged at the start of each billing period. You can cancel online at any time from your dashboard.

Sign in, open your dashboard, choose Manage billing or cancel, then Cancel subscription. You can do it online at any time, without contacting anyone. Kelra keeps working until the end of the period you already paid for, and you are not charged again.

Up to three of your own computers at the same time. Remove one from your dashboard to free a spot. If you try to connect a fourth, Kelra asks you to remove one first. An account is personal and cannot be shared.

Kelra works with agents that support MCP. It has been tested with Claude Code. The Codex setup follows its documented configuration format, and Cursor has not been tested yet. The install guide shows how to connect your agent.

A Mac with Xcode and the iOS Simulator, an AI agent that supports MCP, and Node.js, which provides the npx command that installs and runs Kelra.

Kelra’s analysis tools send the screenshots or image regions a call needs to Kelra’s server, which is built to process them in memory and not save them. Tools that only run on your Mac (taking screenshots, device information, the status bar and the clipboard) send nothing. If a design is confidential, use only those tools. The privacy page has the details.

Kelra measures sizes, spacing, colors and text from screenshots and compares them with your running app. Some values, such as font sizes and weights, are fitted estimates, not exact readings, so check results against the source. Kelra is a developer tool and should not be used for safety-critical decisions.

With Google or GitHub. Your account is created the first time you sign in, and signing in does not start a subscription.

Access may pause until the payment is fixed. You can update your payment method from Manage billing on your dashboard.
