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.

Your conversations are valuable. They should also stay private. Stenographer records, transcribes, identifies speakers, summarizes, and organizes audio directly on your iPhone or iPad. Capture from your phone or Apple Watch, then turn hours of audio into a readable, searchable record without sending your conversations to a transcription service. NEW IN STENOGRAPHER 2.0 • Seamless Transcript Read recordings as one continuous, newspaper-like conversation. Stenographer hides file splits and processing chunks while preserving the original audio behind every turn. • Know who said what Private, on-device speaker diarization separates conversations into natural speaker turns. Name a speaker and Stenographer can use an on-device voice profile to recognize that person in other recordings when there’s a confident match. • Private AI summaries On supported devices, summaries and labels use Apple’s on-device Foundation Models. An optional downloadable local fallback is available, and your transcripts remain on your device. • Record from your wrist Start recording from Apple Watch when reaching for your phone would interrupt the moment. Finished recordings remain queued on Apple Watch and retry until iPhone safely receives them for private transcription and analysis. MORE WAYS TO WORK • Continue recording in the background from iPhone or Apple Watch • Import existing audio files • Automatically detect supported languages • Transcribe speech or translate supported languages into English • Search across transcripts, summaries, and labels • Add labels and optional timestamps • Select exact transcript turns to share • Merge recordings and export all transcripts as JSON • Customize transcript fonts, speaker display, processing concurrency, and recording limits • Return to the classic per-recording layout at any time PRIVATE BY DESIGN Transcription, speaker identification, summaries, and labels run on your device whenever available. Nothing is uploaded unless you explicitly choose to share it. Speaker and optional fallback models may download when needed; your audio and transcripts are not uploaded for processing. ONE PURCHASE. NO SUBSCRIPTION. Record and transcribe without monthly fees, usage quotas, or cloud transcription charges. Ideal for meetings, lectures, interviews, research, personal notes, and private lifelogging.
