Levers Calculator vs Stenographer

The Levers Calculator is a physics/math calculator designed for quick and easy determination of effort force, load force, distance from load force to fulcrum, distance from effort force to fulcrum, or Mechanical Advantage. Features: - Instant calculation. - Results are copyable to other apps. - Formulas included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. Classified into three types based on the location of fulcrum, load, and effort, levers amplify input force to provide a greater output force, creating leverage. The mechanical advantage of a lever is the ratio of the output force to the input force. Classes of levers: 1. Class 1: Fulcrum in the middle - effort on one side, load on the other (e.g., seesaw, crowbar). 2. Class 2: Resistance in the middle - effort on one side, fulcrum on the other (e.g., wheelbarrow, nutcracker). 3. Class 3: Effort in the middle - load on one side, fulcrum on the other (e.g., tweezers, human mandible). Mechanical advantage is a measure of force amplification. It's expressed by the law of the lever, where the moment action on both sides is equal: Fe x De = Fl x Dl Where: - F_e = effort force (N, lb) - F_l = load force (N, lb) - D_l = distance from load force to fulcrum (m, ft) - D_e = distance from effort force to fulcrum (m, ft) The effort force can be calculated using the formula: Fe = Fl x Dl / De Fe = m x g x Dl / De where m = mass (kg) g = acceleration of gravity (9.81 m/s²) Thanks for your support, and please visit nitrio.com for more apps for your iOS devices.

Record conversations. Keep the words. Revisit what mattered. Stenographer 3.0 brings local recording, transcription and source-linked Chat into a cleaner workspace on iPhone and iPad, with Apple Watch recording as a companion. • Record on iPhone or Apple Watch and keep continuous capture together as one conversation. • Read transcripts, play original audio, search words and tags, and edit speaker names. • See live text when processing is available; saved audio remains available when processing is deferred. • Ask about a conversation or your library. Numbered sources open the captured passages behind an answer. • Review action targets before opening, playing, sharing or deleting recordings. LOCAL RECORDING AND TRANSCRIPTION Audio is recorded locally. Watch audio transfers to the paired iPhone for processing. Small multilingual transcription is included and works offline. Settings also offers downloadable Large multilingual; it needs more memory and processing time. Settings also offers optional Distil English-only transcription. Your multilingual settings are saved for switching back. The app shows the selected and actual model, preparation progress and recovery options. Some model failures can use Small while preserving your Large selection. LOCAL AI Apple Intelligence is the default local Chat option on supported, ready devices. You can download and select Qwen3.5-4B for local use. Automatic summaries and tags stay local. Keep the phone app active and idle for pending automatic work to finish. Model availability and speed vary with device, OS, language, downloaded assets and workload. OPTIONAL CLOUD CHAT Bring your own OpenAI, Anthropic or OpenRouter API key and choose a provider model. Keys are stored in device Keychain. Explicit consent is required before cloud Chat sends your current question, selected transcript passages and recording dates and identifiers to the selected provider. Audio files and voice profiles are not sent. OpenRouter may route to another provider. Provider data policies and account charges apply. Failed requests do not silently switch providers. AI, transcripts and speaker attribution can contain mistakes or omissions. Check the original audio and source passages. Sharing uses your chosen destination; deletion requires confirmation.
