Too little checked to say Store information only. We haven’t analysed this app or read its reviews yet.
Not yet tested.
The store currently lists version 4.10, updated 2026-10-28.
Store screenshots supplied by the developer.
Tap Run and the real output appears right under the code, so you know what it does before it goes into your project. No Kotlin to install, no IDE, no setup, no account.
390+ short examples, one task each. Over 95% run on Kotlin 2.4.
You know what you need, but not the exact syntax:
• How do I fall back to a default value when a variable is null?
• How do I return two values from a function?
• How do I merge two maps?
Each has a working example here.…

For developers and the curious
The evidence, sources, measurements and versions behind every label above.
No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured
Not yet tested. No analysis has been run for this app, so there is no version or date to report.
Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
• Run code right in the app: tap Run and the real Kotlin 2.4 output appears under the example. You can also edit an example and run your version. • Kotlin keyword and function reference with 320+ entries. Tap a word in the code to look it up. • New section: what changed from Kotlin 1.4 to 2.0, with before-and-after code. • Improved support for foldable phones and large screens.
Appworthy
kotlin-recipesWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
