Paperless Less Paper vs LumiSync

Less Paper is a native iOS client for paperless-ngx 3.x and earlier, the self-hosted document archive. It talks directly to your own server, and to nothing else. FIND ANYTHING The complete filter set from the web interface, custom fields included: title and content, correspondent, document type, storage path, tags, dates and ASN. Save any filter as a view, then create, edit and reorder your saved views without leaving the app. EDIT WHERE YOU ARE READING Fix a title, reassign a correspondent, add tags, notes or custom field values from the document itself — one Open menu leads to every section: Content, Custom fields, Details, History, Metadata and Notes, each editable when your account allows it. History lists who changed what and when, the way the web UI shows it. Select several documents and change them together, merge them, or delete them in one go. READ IT WITH NO SERVER IN REACH Save a document offline and it is kept on the device in full — the PDF, its notes, metadata and custom fields. The Offline tab reads those stored copies, so it works on a plane, in a basement, or anywhere your server is not. Pull to refresh and only the documents that actually changed are fetched again. GET DOCUMENTS IN Send anything on your device to paperless-ngx from the share sheet. Password-protected PDFs are unlocked on import, and the password is kept in the keychain so the next document from the same source opens without asking. The inbox then says what became of each one: File Tasks lists every import — which finished, which are still running, and which failed and why — and a failure can be dismissed once you have dealt with it. BUILT FOR REAL SETUPS Connect as many servers as you like and switch between them. Sign in with a password, or with the single sign-on provider your server is configured with. Client certificates, custom HTTP headers and reverse proxies such as Authelia are all supported. A restricted account works too: the app follows your user's permissions and simply does not show what you may not do. When something does go wrong, a local error log — with anything credential-shaped redacted out of it — is there to read and share, and nothing leaves the device unless you send it. KEEP THE ARCHIVE TIDY Create, rename and delete tags, correspondents, document types and storage paths, and set ownership and permissions on any document. Restore anything you deleted from the trash, or empty it for good. Works with every paperless-ngx from 2.15.3 to 3.x. Universal: iPhone, iPhone Duo and iPad — on iPad the document opens in a column beside the list rather than covering it. Less Paper is open source.

The Ultimate Remote Stroboscope App for Physics Experiments Enhance your physics experiments and educational activities with LumiSync, a versatile stroboscope app designed specifically for students, educators, and amateur scientists. Transform your iPhone into a precise tool for studying light, motion, and wave phenomena, complete with customizable strobe and solid light settings. Key Features: - Precise Frequency Control (1-60 Hz): Adjust the strobe’s frequency with high accuracy to study periodic motion, resonance, and wave phenomena. Explore the effects of different strobe frequencies on moving objects and analyze motion in real time. - Solid Light Mode (Screen & LED): In addition to strobe effects, LumiSync provides a continuous, solid light source. Choose any color for the screen to explore the visible light spectrum, and utilize the iPhone’s LED flashlight for bright, white light. - Customizable Screen Light Colors: Experiment with different colors on the screen to study wavelength, diffraction, refraction, and other light-related concepts. Perfect for classroom demonstrations or personal learning. - Brightness Adjustment for Optimal Conditions: Control the brightness of the screen to suit different experimental environments, ensuring precise lighting whether you’re in a bright lab or a dark room. - Remote Control via Web Portal: Conduct hands-free experiments with LumiSync’s web-based remote control. Each user receives a unique 6-character code, allowing them to control the app remotely—ideal for group experiments or educational demonstrations. - Dark Mode UI: LumiSync’s sleek dark mode ensures a comfortable experience in low-light environments, reducing screen glare and making it easier to focus on your experiments. Educational and Experimental Applications: - LumiSync is designed to be a valuable tool for physics and science education: - Wave and Motion Studies: Use the strobe function to visualize wave patterns, harmonic oscillations, and the motion of rotating objects. Investigate the relationship between frequency and motion in real time. - Color and Light Exploration: Experiment with solid light in various colors on the screen to explore concepts such as the visible spectrum, light absorption, and color theory. Switch between the customizable screen and the white LED flashlight for diverse lighting effects. - Motion Analysis: The strobe function enables high-frequency flashing, helping you freeze and slow down the motion of fast-moving objects, making it easier to analyze rotational or oscillatory motion in physics experiments. - Remote Learning and Classroom Demonstrations: LumiSync’s remote control feature, accessible via the web, allows teachers and students to control the app from any device, facilitating hands-free demonstrations and distance learning.
