Proselens: Writing Style Guide

Proselens is a readability lens for the second draft. Paste or type on iPhone or iPad and it marks the sentences worth another look, scores the text with six published readability formulas, and keeps everything on your device. NEW IN 5.0 • Consistency check: finds a word spelled two ways (colour and color, -ise and -ize), written with and without a hyphen (e-mail and email), capitalized differently mid-sentence (Internet and internet), and small numbers written both as numerals and as words. Tap a form to jump to it in your draft. • Readability history: each save records the document's word count, sentences, Flesch–Kincaid grade, Reading Ease and clarity, charted over time so you can see what your revisions changed. • Repeated phrases: three-to-five-word phrases you use more than once, listed in Insights and in the PDF report. • Check Readability in Shortcuts and Siri: measure any text and get grade, Reading Ease and reading time back. • More accurate scores: a rewritten syllable counter agrees with dictionary syllable counts on 386 of 387 test words (4.x: 319), so grade levels are no longer inflated by words like "table" and "people". LIVE HIGHLIGHTS Very hard and hard sentences, sticky sentences, passive voice, -ly adverbs, vague qualifiers, clichés and redundant phrases, and complex words with plainer alternatives are marked as you type. Tap a highlight to see why, focus one category, or switch off any check. SIX READABILITY FORMULAS Flesch Reading Ease, Flesch–Kincaid Grade, Gunning Fog, SMOG, Automated Readability Index and Coleman–Liau, with each formula and its limits explained. Compare the estimate with an audience band such as Grade 8 or Plain language. INSIGHTS Glue index, transitions, sentence openers, rhythm, close word repeats, repeated phrases, pacing by paragraph and word frequency. HOUSE STYLE Save your preferred terms, review every match in context and replace one occurrence at a time. The original draft is kept in revision history first. REVISIONS AND LIBRARY Save drafts to a local library, compare revisions side by side, restore snapshots, and export a PDF or text report or a full library package. WHAT TO KNOW Readability formulas are estimates for English prose. They do not measure comprehension, accessibility or writing quality. The clarity score is Proselens's own 0–100 composite, not a published standard. The consistency check compares only forms already in your draft and does not know proper names or your style guide. EVERYTHING INCLUDED One purchase. No subscription, no account, no ads and no analytics. The app has no networking code: your writing stays on your device.
