ZeroAds vs Graincount

Some sites turn every tap into an ad. You press play and a new tab opens. You tap "next chapter" and land on a scam page or the App Store. ZeroAds is a browser that keeps you on the page. Turn on the shield, and links that try to take you somewhere else simply don't go. No redirects, no pop-up tabs, no forced app opens. MADE FOR • Free video, sports and anime sites that open an ad on every tap • Manga, comics and web-novel sites with hidden ad links • News and recipe pages covered by full-screen ad overlays • Anyone who keeps landing on "your iPhone has a virus" pages HOW IT WORKS 1. Browse as usual. Search with Brave, Google or DuckDuckGo. 2. On a page full of traps, turn on the shield. You stay on that site. 3. Want to go somewhere else? Open a new tab, or turn the shield off. ALSO • Blocks ads with the EasyList filter (about 90,000 rules) • Removes full-screen overlay ads • Skips video ads on YouTube • Tabs that are still there when you come back • Bookmarks, pull to refresh, and a landscape lock for videos • Long-press a link to open it in a new or background tab Free, no account needed.

Graincount: Microstructure is a planar grain-size worksheet that keeps a human at the eyepiece. It opens on a labeled synthetic worked example, so the whole workflow is visible before you import anything of your own. Does it segment grains for me? No, and that is deliberate. You import a micrograph as immutable evidence, then place, classify, and weight every intercept crossing or grain tally yourself; the app's job is geometry, arithmetic, and record-keeping, never automated detection. How do my marks become a grain size? A two-point calibration against a feature of known length (nm, um, or mm) fixes the scale. Accepted marks on drawn intercept lines pool into a Heyn-style mean intercept, while counts inside planimetric frames yield grains per square millimetre and an equivalent-circle diameter, with sample standard deviation reported across fields. Will the number survive an audit? Every commit becomes an immutable revision: the snapshot is canonicalized, hashed with SHA-256, and chained to its parent. You can inspect any revision's diff, restore an older one as a new revision, and export the worksheet as a project package, CSV, or PDF that states its own limitations. Everything computes and stays on your own device, and one purchase covers the app for good - no subscription meter running.
