Doremia
Read full descriptionHide full description
Doremia is an ear training app that helps you develop relative pitch by listening to piano notes and identifying them as Do, Re, Mi, Fa, Sol, La, and Ti. Practice through structured lessons based on a musical key, and gradually improve your ability to recognize the role of each note within that key. Unlike absolute pitch, which is typically developed at a very young age, relative pitch can be trained and improved at any age. Doremia is designed for anyone who wants to strengthen their listening skills and deepen their understanding of music. Doremia focuses on hearing notes as functions within a key rather than as fixed note names. For example, in C major, C is "Do." In D major, D becomes "Do." By training with movable Do, you learn to recognize how notes relate to each other and where they fit within a musical context. How It Works 1. Choose a lesson or create your own 2. Listen to the tonic note or cadence to establish the key 3. Listen to the note sequence 4. Answer using the on-screen piano keyboard 5. Review your results and track your progress Each question is graded individually, allowing you to immediately identify mistakes and focus on the scale degrees that need more practice. Main Features ■ Custom Lessons Create lessons tailored to your goals. • Select musical keys • Choose tonic note, cadence, or no reference tone • Set the number of notes per question • Set the number of questions • Adjust note duration • Select which scale degrees to include • Choose pitch ranges (such as C4–C5 or C5–C6) • Enable or disable velocity variation • Edit, duplicate, and delete lessons ■ Ear Training Exercises Listen to note sequences and answer using the piano keyboard. Movable Do labels are displayed on the keys, helping you focus on scale degrees rather than fixed note names. You can undo your last answer, clear all answers, and replay questions as often as needed. Replay options include both the reference tones and the question notes, or just the question notes alone. ■ Listening Mode Improve your ears even when you don't want to answer questions. • Major and minor scales • Interval exercises from 3rds to octaves • Ascending, descending, and round-trip patterns • Tempo adjustment • Key selection Perfect for warming up before practice sessions or training your ears while on the go. ■ Keyboard Use the built-in keyboard to freely explore notes and scale degrees. ■ Progress Tracking All practice data is stored locally on your device. • Accuracy by lesson • Accuracy by scale degree • Weekly, monthly, and lifetime statistics • Session history Track your strengths and weaknesses. Who Is This App For? • Musicians who want to develop relative pitch • Singers practicing movable Do • Students studying solfège and dictation • Instrumentalists who want stronger listening skills • Anyone interested in ear training • People who want to improve karaoke pitch accuracy • Musicians working on transcription and ear-based learning • Busy learners looking for short daily practice sessions Why Doremia? ■ Practice at Your Own Level Customize lesson difficulty by adjusting keys, note ranges, scale degrees, and more. ■ Focus on Movable Do Train your ears to recognize note functions within a key rather than memorizing fixed note names. ■ Natural Piano Sound Doremia uses SoundFont piano samples for a clear and realistic listening experience. Optional velocity variation adds subtle dynamic differences, creating a more natural musical environment. ■ Works Offline Lessons, listening exercises, and progress tracking all work entirely on your device. No account required. Spend a few minutes each day training your ears and discover the power of relative pitch.

Hangul Go sends you one Korean word at a time — right on your Lock Screen and Home Screen. No lessons to sit through, no streaks to protect. Just small moments throughout the day that build real vocabulary. HOW IT WORKS Start with a quick placement quiz — a couple of short rounds, not a big test. Don't know a word? Just skip it. This places you at the right starting level: Survival, Beginner, TOPIK I, or TOPIK II+. From there, Hangul Go quietly works in the background. A new word appears on your Lock Screen and Home Screen widget throughout your active hours, with its English meaning right there — no need to open the app. LEARN AT YOUR OWN PACE Every word moves through four stages as you learn it: New, Learning, Almost Known, and Known. Track your progress at a glance on your dashboard, organized by category — everyday conversation, food & drink, travel, and more. Pick as many categories as you like, or focus on just one. When you're ready to actively review, jump into a quick batch quiz, or look up any single word on demand. Each word comes with a real example sentence and its translation, so you're learning vocabulary in context — not just isolated flashcards. BUILT FOR DAILY LIFE • Home Screen and Lock Screen widgets — glance and go • Placement quiz that adapts to what you already know • Four Korean proficiency levels, from complete beginner to TOPIK II+ • Category-based learning: everyday conversation, food & drink, travel, and more • Word progress tracking: New → Learning → Almost Known → Known • Quick batch quizzes and on-demand word review • Real example sentences with every word • Full iPad support Hangul Go is free to start. An optional subscription unlocks the complete word library and higher proficiency levels. Whether you're prepping for a trip to Korea, studying for the TOPIK exam, or just want to pick up a few real words a day without the pressure of a full course — Hangul Go fits Korean into the moments you already have.
