Suiyomi
Read full descriptionHide full description
Suiyomi trains one thing, and trains it well: your ability to read sheet music. "Suiyomi" comes from the Japanese "suisui yomu" — to read smoothly, without stopping to count lines. Knowing a note the moment you see it is exactly what this app trains. ■ Real staff notation, not a simplified stand-in. The thing we care about most is that every question is drawn on a proper staff, exactly as it appears in real sheet music — note positions, ledger lines, key signatures, and the way chord noteheads line up. Nothing is replaced with icons or simplified shapes. That means the notes you learn to recognize here are the same notes you'll read on the page in front of you. It plays like a game; what you take away is genuine sight-reading ability. ■ The staff moves. Notes don't appear one at a time. They line up across the staff the way they do in real music. Answer the note in the middle and the whole staff scrolls left, bringing the next note to the center. When you read music, your eyes stay slightly ahead of the note you're playing. Reading a staff that keeps moving lets you practise with that same habit. WHO IT'S FOR • Beginners on piano or any other instrument • Anyone who counts up the lines note by note • Players who want to sit down and play from a score • Students filling the gaps between lessons • Children learning music MAIN FEATURES ■ Note reading training Read the note on the staff and answer on the piano keyboard. A session can be completed in as few as 10 questions, so it fits before a lesson or on the way to work. ■ Treble and bass clef Both clefs are supported. Choose a range that matches your level, from notes that stay inside the staff to the full range with ledger lines. ■ Chord training (2, 3 and 4 notes) From two-note intervals to seventh chords. Chords that actually appear in real music show up more often, so what you practice is what you'll meet on the page. You can also pick the range: no ledger lines, standard, or full. ■ Key signatures Practice in sharp and flat keys — preparation for playing real pieces. ■ Weak point mode Notes you keep missing come up more often, so you can clear your weak spots efficiently. BUILT TO KEEP YOU GOING ■ Streak and daily progress Your practice streak and today's question count are right on the home screen. ■ Combos Consecutive correct answers build a combo, adding a bit of speed and pressure. ■ Over 80 badges Mastered notes, streaks, speed, chords — collect badges across a wide range of goals. ■ Proficiency level per note Every single note carries a proficiency level from 0 to 5, so you can see at a glance which notes you still can't read. STATISTICS • Accuracy and response time • Practice history charts • Proficiency for each note ALSO • Works offline • All records stay on your device (no account needed) • Dark mode • Sound effects and music can be turned off • Available in English and Japanese A few minutes a day. Reading music gets easier every time.

■ "Wait, how many was it again?" "100 points 10 times for an allowance." "30 chores for game time." We make these promises, then we forget. Kids have good days and off days too. On a 0-page day, do we trash the whole week? TodoBank saves your kid's effort and your promises into a savings book. Deposits add up, withdrawals cover off days. What got done actually stays. ■ How it works (3 steps) ① Parent creates a savings book (e.g. kanji, dishes, 100-point tests) ② Kid deposits the effort they did On off days, kid withdraws from savings ③ Note the reward (10 pages = a snack) Pick the cover, pattern, and icon. Kids grow their own savings book. ■ Never forget a promise again "100 points × 10 for an allowance." "30 chores for screen time." We make these. Then we drop them. The savings book keeps count, so "how many was it?" disappears. The notes field saves the whole deal, including the reward itself. For kids, seeing distance-to-reward makes today's one page actually mean something. ■ Smooth out the wobble "One page a day" is the plan, but motivation comes in waves. Some days 5 pages, some days zero. TodoBank lets kids deposit when they do, and withdraw when they don't. A zero day isn't a fail if the total still moves. "If I bank some now, next week is easier." That thought turns good days into bigger ones. For perfectionist kids, "I'm still going, even with waves" becomes its own confidence. ■ No interest paid Unlike a real bank, savings here don't grow. But they don't shrink either. What got done actually stays. Yesterday's effort carries into today. The daily reset goes away. ■ No cheating — passwords Set a deposit password in the parent settings, so kids can't inflate the balance. Optional. If unset or forgotten, a simple mental math problem lets the user in — kids never get fully locked out. ■ Lots of savings books Kanji, math 100s, dishes, English recitation… one savings book per task. Cover, pattern, icon, all customizable. Kids collect their own savings books. ■ This app supports families with · Strong ups and downs in motivation · "I missed yesterday, so forget it" all-or-nothing thinking · Perfectionism (less than 100% = quit) · Curiosity about money management · Promises that mustn't be forgotten · "How many more?" anxiety that needs a visible answer · A child with ADHD, ASD, HSC traits, or a sensitive temperament where steady follow-through is hard These are everyday realities for many kids. TodoBank uses the "it's accumulating" feeling to keep things going through uneven days. ■ Safe to use · Ads appear only on the parent admin screen. The kid's savings book view is ad-free. We don't track users. · All your kid's data stays on the device. Nothing is sent out. May daily parent-kid time feel a little lighter. ■ Sister apps "TodoFarm" — for all-or-nothing kids — a habit tracker that grows by the amount done. "TodoGatya" — for slow mornings — kids draw the next task from a gacha and start with a surprise.
