iCrucible is an AI tool for Materials Science. Using this app, you can learn about how AI tools work for materials screening, and may discover candidate compounds. Learn more at our website: https://www.rimcs.co.jp/ iCrucible makes a prediction of a ternary system on your iPhone or iPad without external services, using graph neural networks and crystal prototype databases bundled in the app. You can watch the phase diagram redrawn at the end of each stage during performing the prediction task. Note that it is the phase diagram at absolute zero (i.e., 0 kelvin) and around zero pressure (i.e., 0 kilobar). Performance It takes a few seconds to minutes depending on the creation settings and your device. The app has a multithreading option to accelerate the core of the AI tool - for example, computationally intensive tasks are sped up around 2.5x on M1 iPad Air. Chemical System A chemical system is selected by choosing three unique chemical elements from: • Element List (with group and period restriction) or • Periodic Table Materials Screening The materials screening is conducted by thresholding two values: • Predicative Variance • Stability (Energy above Convex Hull) Phase Diagram Drawing The drawing is customizable and responsive with useful features: • Formula Labeling • Stability Thresholding • Zoom • Mark Size • Font Size • Balloon with each compound information Confidence Chart The chart shows the distribution of predicative confidences, and provides an overall confidence of the system prediction and the phase diagram. Compound Table The table shows stable and metastable compounds with stabilities and predicative confidences, from which you can easily choose candidate compounds. Settings You can set the default preferences of the chemical system creation and the phase diagram drawing in the App's Settings. The entrance of the In-App Shop is also located in the App's Settings. We offer Free, Standard, and Premium plan. You can subscribe to one of Standard and Premium plan at the In-App Shop. The Shop's Help describes the system tiers used for the content management. Free features: • Free Elements: H to Ar. (*) • Ensemble Size: M = 1. • Prototype Database: Small only. • You can take a note about each chemical system to not forget any novel findings and great ideas. Standard features: • Standard Elements: K to Xe. (*) • Ensemble Size: M is not more than 5. • Prototype Database: Small, Medium, and Large. • You can sort chemical systems into Stocks that are a storage for them. • Chemical systems can be shared between your devices by peer-to-peer Wi-Fi networking. Premium features: • Premium Elements: Cs to Pu except Po to Ra. (*) • Ensemble Size: M is not more than 10. • Prototype Database: all scales, that is, Small, Medium, Large, and Huge. • Multithreading can be used to accelerate the core of the AI tool - for example, computationally intensive tasks are sped up around 2.5x on M1 iPad Air. * Noble gas elements are not available. Flame Gems You need flame gems for a non-free system creation, and can buy them at the In-App Shop. The Shop's Help describes how to consume flame gems and has the cost calculator. You have to buy no flame gems if you are on the Free plan. Terms of Use: http://www.apple.com/legal/itunes/appstore/dev/stdeula

About

Skyview

Features
Read full description

Skyview is a viewer and management app for home and small-business cameras. It pairs with a Skyview server you run yourself, and is designed for IP cameras that speak the RTSP / ONVIF standard. — What this is — Skyview is NOT a public cloud service and does not connect your cameras to the internet for you. You first set up the Skyview server on a PC, NAS, or mini-PC at home, attach your cameras to it, and then use this app on iPhone / iPad to view and manage everything. All video and events stay on your own hardware — nothing is uploaded to any third-party cloud. — Features — LIVE VIEW • Grid dashboard with live thumbnails of every camera at a glance • Tap any camera for full-screen view; low-latency WebRTC by default, with automatic fallback to HLS on weaker networks • Two-way talk (push-to-talk) for talking with family or warning off strangers • PTZ control: pan, tilt, zoom, and preset recall on supported cameras TIMELINE PLAYBACK • Smooth, second-precision timeline scrubbing • Variable-speed playback, jump to any moment • Highlights segments that contain events or recorded footage • Save clips to your iPhone's Photos library AI EVENTS & ALERTS Powered by the detection pipeline on your server, the app receives and displays: • Motion, person, vehicle, and pet detection • Face recognition (enroll family members in-app; get a separate alert for unknown faces) • License-plate recognition • Fall detection (helpful for homes with elderly family members) • Custom detection zones, sensitivity, and quiet hours Push notifications arrive on iPhone the moment an event fires; tap to jump straight to the moment in the recording. EVENT CENTER • Reverse-chronological event feed with thumbnails and type tags • Filter by camera, event type, and time range • Jump directly to the recorded video at the event's timestamp USERS & SHARING • Multiple accounts can sign in to the same server • Admins create standard users and limit which cameras they see • Change password, sign out, and switch servers from inside the app RECORDING & STORAGE • Server records each camera in segments; the app shows free space and retention days per camera • Direct playback links with seek and speed control VOICE ANNOUNCEMENTS (Optional) • If you enable server-side automation, cameras can speak a phrase out loud when an event triggers (for example, "Unknown visitor detected — owner has been notified"), turning monitoring into active deterrence. — What you'll need — 1. An RTSP / ONVIF compatible IP camera (most home IPCs qualify) 2. An always-on PC, NAS, or mini-PC to run the Skyview server 3. After the one-time server setup, enter your server address in this app and sign in. Cameras that use proprietary protocols (Tapo, Mi Home, Wyze, etc.) need to be bridged to RTSP first using a tool such as go2rtc. — Privacy — • All video, recordings, and AI results live on YOUR server • Push notifications carry only event type and camera name — no imagery is sent through Apple's push pipeline • The app collects no analytics, contains no third-party tracking SDKs — About offline use — This app depends on your home server. If the server is offline or unreachable, live and recorded video are not available. Run the server on hardware that stays on 24/7, and configure a stable remote-access method on your home network (see the server documentation for details). Questions or feedback? Reach us from Settings → About inside the app. Privacy Policy: https://yun-kan.com/privacy Terms of Use (EULA): https://yun-kan.com/terms
