Rot Stop is a privacy-first iOS app that helps you stop digital rot by blocking distracting apps using NFC tags, schedules, usage limits, or any combination. No subscriptions. No cloud. How Rot Stop Works - Choose the apps you want to block: social media, games, shopping, or anything distracting. - Create multiple groups for different contexts (work, study, sleep) - (Optional) NFC tags: scan a physical tag to lock or unlock. Real-world friction you can't tap through. - Schedules: auto-lock apps at specific times and days (work hours, bedtime, weekends) - Usage limits: auto-block apps after a daily time threshold - Mix and match: add a schedule and an NFC tag to the same group Your Pet Rot Stop includes a virtual pet that mirrors your habits. Lock apps daily and your pet stays happy. Skip a day and it starts to worry. Miss a full week and it reverts to an egg. Why NFC? Your focus is protected by something you can't tap through. Schedules and limits work automatically, but for the moments you want full control, an NFC tag creates a physical pause between impulse and action.

Pottr is a pottery journal for ceramic artists, hobbyists, and students. Document every piece you make — from raw clay to the final firing — with stages, technical data, photos, sketches, and reusable material libraries. Everything lives in your private iCloud. No accounts, no servers, no ads, no tracking. — STAGE TIMELINE — Track each piece through its lifecycle: To Do → Formed → Trimmed → Bisqued → Glazed → Finished. Stage dates auto-log as you advance, with editable history and auto-fill when you skip ahead. — FIRING LOGS — Record every firing with method, atmosphere, temperature or cone, and notes. Toggle between °C / °F and Orton cones with automatic conversion. — DECORATION LAYERS — Capture glazes, slips, underglazes, oxides, and stains per piece. Each layer logs surface area, application method, and coat count, and references reusable material libraries. — MATERIAL LIBRARIES — Six pre-seeded libraries — clay bodies, glazes, slips, underglazes, oxides, stains — with real-world products from Amaco, Mayco, Coyote, Spectrum, Laguna, Standard Ceramic Supply, Highwater, Scarva, Valentines, Cerama, Silica Nordic, Mason, and more. Add your own at any time. Search, favorites, and filters by manufacturer, country of origin, and firing range. — DIMENSIONS & WEIGHTS — Track height, width, depth, and weights at each stage (wet, leather hard, bisque, finished). Metric and imperial both supported, auto-detected from your device. — SHRINKAGE CALCULATOR — Calculate wet-to-fired or fired-to-wet sizes from any clay body's shrinkage percentage. Plan your forms with confidence. — SKETCHES — Draw designs with Apple Pencil or your finger. Sketch standalone or attach to a project. Multiple sketches per piece, all editable. — PHOTOS & VIDEOS — Capture or import photos and short videos per project. Configurable quality, with optional bulk recompression to free up storage. — SHARING & EXPORT — Generate a multi-page PDF report or a single image card from any project — choose what to include. Share full projects as .pottr files (a portable bundle of JSON, photos, videos, and sketches). Export material libraries as CSV. — ICLOUD SYNC — Automatic sync across iPhone and iPad via your personal iCloud. Offline-first — works with no signal and catches up when you're back online. Nothing is sent to any third party. — SEVEN LANGUAGES — Available in English, Spanish, French, German, Italian, Catalan, and Danish. Switch the app language independently of your device language. — FREE WITH OPTIONAL TIPS — Pottr is free with no ads, no subscriptions, and no tracking. If the app earns a place in your studio, you can leave a one-time tip — purely optional, never gated. Made by a hobbyist for hobbyists.
