I had to read the headline twice because it literally missed a space: “Stop forgettingwhat you read.” And then you brag “Type the title. That's the whole job.” which is crisp — except the site messes the punctuation elsewhere (“Any book.Just the title.”).

Some lines are crisp and memorable (type the title, five minutes a day) but sloppy punctuation and small contradictions make the page look half-done and raise credibility questions.

Fix the obvious typos and replace the hero with a single clear line and subline. Example: Headline: “Stop forgetting what you read.” Subline: “Type the title. Get a deck of original flashcards in seconds. Review five minutes a day.”

You hint at different people — audiobook listeners, highlight-haters, non-fiction fans — but you never pick one and speak to them directly. “Any book” sounds powerful, but it’s also vague.

Headings show a scatter of use-cases (audiobooks, guides, non-fiction technique) without a single sharp sentence: who should download this right now and why it matters to their life.

Add a one-line audience-targeted subhead under the hero. Example: “For busy non-fiction readers and audiobook lovers who want to keep ideas, not just impressions.”

The core promise is good: you read a book, Kern makes cards, spaced repetition keeps them. “Five minutes a day” is a great stick — I buy that. But you never back up the ‘seconds’ or what ‘keeps ideas alive’ actually means.

Readers get a clear benefit (retain more) and a low time cost claim. Missing: an explicit outcome (how much longer, or what ‘keeps alive’ looks like) and a quick line on the uniqueness vs. highlights or summaries.

Boil it to one result-driven sentence. Example: “Turn any book into a reusable deck in seconds and retain its best ideas with five minutes of review a day—so months later you can still explain it.”

You say “No account, no sign-up, fully offline reviews,” then end with “Kern Plus unlocks unlimited books.” That reads like: magical privacy until you want to pay—how does that work? Also the app claims cards from the book’s ‘original language’ — sounds legal-gray without clarity

Privacy and payment flow currently contradict. People will trip over: Do I need an account to unlock unlimited books? Where is my data stored? The App Store reviews are good, but they don’t answer the core trust questions.

State the payment and privacy flow in one sentence under pricing and again in Privacy: e.g. “Buy Kern Plus in-app (no account needed); your decks stay on your device and reviews work fully offline.”

There are links like “Get the app” and “Download on the App Store” buried in the links list, and the buttons array is empty. The page promises ‘first two books free’ but never makes the primary CTA scream it.

Users need a single obvious button in the hero: tells them what they get and reduces friction. Right now they have to hunt and mentally reconcile free-to-start vs. Kern Plus.

Add one primary CTA button in the hero: “Get the app — two books free.” Secondary: “How it works” or “Watch demo.” Make the App Store badge visible next to it.
