Byeoldosa vs EverMind Flashcards

Byeoldosa is an arithmetic practice app for working through addition, subtraction, multiplication, and division step by step. • Levels are organised by difficulty, so you can start from the basics and move on to more advanced problems at your own pace. • Problems range from single-digit to three-digit numbers, with stages that change depending on whether carrying or borrowing is involved. • In vertical (column) calculation mode, you can follow each column one box at a time, much like writing out the sum on paper. • Every practice set is saved automatically, and your scores and time spent are shown in simple charts, so you can see how your speed and accuracy change as you keep practising. It’s a good fit for students who want to strengthen their arithmetic, for anyone who’d like a bit of mental exercise, or for those moments when you just feel like doing a few number problems. Whenever you feel like practising numbers, just open Byeoldosa.

Turn any notes into an exam-ready study plan — private, offline, with on-device AI. EverMind is a spaced-repetition flashcard app built for anyone studying toward a dated exam — certifications, boards, finals, language tests — and for anyone who wants serious spaced repetition without the clutter of legacy flashcard apps. Your first review is ready in under 60 seconds, with zero required setup. WHY EVERMIND IS DIFFERENT - Deadline Mode — Attach an exam date and a daily time budget. The scheduler works backward from your exam date using the FSRS forgetting curve, giving you an honest readiness forecast, a projected workload curve, and a clear triage list if the plan doesn't fit your schedule. Nothing is silently dropped. - Real spaced repetition, zero configuration — FSRS-5 scheduling (stability, difficulty, retrievability) with no settings required: think, tap to reveal, then swipe to mark Forgot or Remembered. One-step undo restores your schedule instantly. - Learning-science study modes — Free recall by default (recognition is weaker for retention), typed answers with fuzzy matching and AI-assisted suggestions, and multiple-choice as deliberate exam simulation with on-device, embedding-based distractors. - Offline and private by design — Built with SwiftUI and SwiftData. No account, no server, no analytics, no third-party SDKs. Your study material stays on your device, and AI generation runs on-device when available. No study content is ever uploaded. - AI card generation with receipts — Paste your notes and let on-device AI draft Q&A, cloze, multiple-choice, and vocabulary cards, each anchored to the exact source text. Drafts wait in an approval inbox — nothing enters your study deck until you accept it. - Overnight preparation — While your phone charges, a background task finishes card generation and prepares tomorrow's review sets, with battery and thermal-aware safeguards. - Easy in, easy out — Import CSV/TSV (including Quizlet exports) and Anki .apkg decks with full review-history replay, plus JSON backup/restore and CSV export. - Offline pronunciation using on-device, language-specific voices. - Full iPad support with the same private, offline experience. EverMind includes a 14-day free trial. After the trial, unlock the app forever with a single one-time purchase — no subscription, no ads, ever.
