This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, plus small display fixes. iPhone is unchanged.

PostProof 2.0 — a pro upgrade for your final pre-post check, still fully offline and on-device. • Loudness & silence check: integrated loudness and true-peak vs. the short-form sweet spot, with a clear too-quiet / clipping verdict. • Text dwell-time checker: flags on-screen text that flashes by too fast to read, line by line. • Letterbox / pillarbox detector: catches black bars that read as a lazy cross-post and cut your reach. • "Works everywhere?" cross-layout report: tests your text against every platform's chrome in one pass. • Cover-frame audit: exposure, sharpness, contrast, a credibility cue, and safe placement for your first frame. • Export a PDF proof report bundling every score and fix. No account, no network, no uploads — your clip never leaves your device.

What's New in PostProof 1.3 Best-Layout Recommendation After FrameCheck runs, a new panel immediately below it ranks all 10 layouts best-to-worst for your specific clip - by covered regions, worst coverage ratio, duration fit, and aspect match. The top pick gets a hero card with a plain-English reason ("Nothing gets covered and the shape is native.") and a Fit score. Tap it to switch to that layout instantly. The remaining 9 are shown as compact chips in ranked order, so you no longer have to read all 10 manually to find the cleanest option. Cover Frame Scrubber The cover picker now includes a full-range time scrubber that lets you pull any exact frame from the clip - not just the 4-8 auto-sampled options. Drag the slider to any second, and PostProof extracts that frame on-device, scores it with the same sharpness, contrast, and face-detection pipeline used during analysis, and previews it with a comparable score pill. The auto-sampled picks stay visible below for quick reference. Hashtag Presets (Offline) The caption pack now includes 10 bundled hashtag sets by creator category - Education, Comedy, Lifestyle, Beauty, Fitness, Food, Tech, Travel, Music, and Creator Growth - 80 tags total, all offline. Tap a category chip to expand its tags, then hit "Add" to merge them into your hashtag draft (skipping any duplicates) or "Replace" to swap the draft entirely.

What's New in PostProof 1.2 Stop Score Trend Chart The Proofs tab now shows a live trend chart of your Stop Score across your last 20 saved proofs, with a rolling average reference line and Latest / Best / Avg stat pills. See at a glance whether your edits are actually moving the needle. Compare Mode Long-press any saved proof to pick a second one and open a side-by-side comparison. Every metric — Stop Score, Muted OK, Loop, and Covered regions — shows the exact delta and a winner indicator so you can A/B-test two versions of the same clip before choosing which to post. Proof Detail Sheet Tapping any row in Proofs now opens a full detail view with a score progress bar, metric tiles, your saved caption (with one-tap copy), cover-time, layout, and a copyable breakdown text you can paste anywhere.

Pixel-accurate, and clearer than ever. New — exact 2026 safe-zone specs for 10 vertical layouts, partial-coverage percentages instead of pass/fail, a caption-placement studio, explainable score breakdowns, a specs cheat-sheet, a captions library, and saved-proof history. Fully offline. No account, no ads, no tracking.
