Flashcards Maker vs Frequency Loom

FlashCard is a beautifully simple flashcard app that uses intuitive swipe gestures to help you memorize anything—fast. Designed for vocabulary building, exam prep, language learning, and any subject that requires memorization. ■ 3 Key Differences 1. Swipe to Memorize Left = need review. Right = got it. No tapping, no menus. Flip through cards at your own pace—on the bus, in class, or the night before an exam. Built for speed and rhythm. 2. Beautiful, Minimal UI Clean typography, smooth animations, dark mode. We stripped away the clutter so you can focus on one thing: memory. 3. 100% Offline, No Account Everything lives on your device. No sign-up, no login, no internet required. Start studying in seconds. ■ Powerful Study Features - Spaced repetition (SRS) based on the forgetting curve - Unlimited decks & flashcards - Image cards for diagrams, photos, and visual memory - Audio recording & playback for pronunciation practice - Text-to-speech (TTS) for multiple languages - Shuffle & random review - Folder organization by subject - Daily study reminders - Hidden-answer review mode - Works great as an Anki-method alternative — simpler and prettier ■ Track Your Progress - Correct/incorrect stats per card - Clean progress dashboard - Daily & weekly study graphs - Automatic "weak cards" pick-up for focused review ■ Perfect For - Language learners (Spanish, Japanese, Korean, French, Mandarin, and more) - Exam prep: SAT, ACT, GRE, MCAT, LSAT, bar, nursing boards, USMLE - College & high school students building vocabulary - Medical, nursing, and pharmacy students memorizing terminology - Law students studying cases and rules - Programmers learning syntax, APIs, and algorithms - Kids & toddlers — a calm, ad-free way to learn words - Anyone who wants a simple, beautiful way to memorize ■ What You Can Study Vocabulary words, foreign languages, historical dates, scientific terms, medical terminology, legal concepts, math formulas, programming syntax, music theory, cooking recipes—if you can put it on a card, FlashCard can help you memorize it. ■ Privacy First All study data stays on your device. Nothing is sent to servers. No tracking, no ads. Use with complete peace of mind. FlashCard—memorize smarter, not harder.

See what changed at a position Change Desk compares two intact sealed acoustic runs at the same planned position. Rank band-level changes and share a report linked to the exact stored evidence. • Open a commissioning project → Verify → Change Desk. • Choose baseline and later runs at the same planned position. Confirm comparable stimulus level, gain, microphone position and room conditions. • Compare broadband and matching-band changes, then share the frozen evidence references. Both runs must be accepted, nonvoided and seal-valid, with matching input chain, route, sample rate, scale, stimulus and band set. Matching metadata cannot prove matching physical conditions. Differences are not a transfer function, EQ recommendation or proof of improvement. Frequency Loom is an acoustic commissioning fieldbook for installed sound systems. It turns a listener-area plan into a traceable record of positions, witnessed microphone runs, acceptance results, and handoff evidence. Start with the job, not a generic meter. Record the site, room, work order, operator, client witness, installed system, microphone, interface, channel, and field calibration context. Lay out one or more listener areas with named measurement positions, microphone heights, plan coordinates, notes, and required repeat counts. At each position, capture a live evidence run while the installed sound system or another external source plays pink noise, speech-shaped noise, program material, or a sweep; use Ambient only for background capture. Frequency Loom records broadband RMS, one-third-octave band values, active input route, sample rate, captured duration, clipping, and level stability. Short, clipped, unstable, incomplete, interrupted, or route-changing runs are held out of verification instead of being silently treated as valid. The acceptance matrix evaluates project-defined targets for: - Planned position coverage - Listener-area level spread - Worst cross-position band spread - Repeat-run agreement - Optional referenced ambient and commissioned-level limits Every retained run receives a deterministic SHA-256 evidence seal. Later changes cause an integrity mismatch and exclude the run. Voided runs stay visible as ledger events. Export the complete job as structured JSON, CSV, or a readable commissioning report through the iOS share sheet. The commissioning workflow requires no account or developer network service and works offline; Methodology links open external reference websites only when you tap them. Microphone samples are analyzed on device and are not saved as audio. Projects remain in private local storage until you deliberately export them. There are no analytics, ads, tracking SDKs, remote flags, or subscriptions. Uncalibrated work is labeled relative dBFS. A documented reference match can produce referenced dB SPL values, but Frequency Loom does not claim that an iPhone, microphone, calibrator, or input chain conforms to IEC, ISO, ANSI, or AVIXA standards. The app is a commissioning evidence fieldbook, not a class-rated sound level meter or standards certificate.
