Practice Statistics
Track your practice time, accuracy, and progress over time. Crescendo records your sessions automatically and presents them through charts and metrics.
Quick Overview
- ✓ Automatic tracking — Practice time and accuracy recorded every session
- ✓ Streak tracking — See how many consecutive days you've practiced
- ✓ Weekly goal — Set a target for how many days per week to practice
- ✓ Charts and heatmaps — Visualize your progress with bar charts, accuracy trends, and a 12-month calendar
1 Accessing Your Statistics
There are two ways to view your practice statistics:
Overall Statistics
Go to Settings and tap "View Stats". This shows your combined practice data across all pieces.
Includes streak, weekly goal, calendar heatmap, and time breakdown.
Per-Piece Statistics
In your Library, tap the three-dot menu on any piece and select "View Stats". This shows detailed statistics for that specific piece.
Includes accuracy trends, session history, and learning phase.
2 What's Tracked
Every time you practice, Crescendo automatically records:
| Metric | Description |
|---|---|
| Practice Time | Duration of each session in minutes |
| Accuracy | Percentage of notes played correctly (0-100%) |
| Hand Mode | Whether you practiced Right, Left, or Both hands |
| Session Count | Total number of practice sessions |
| Last Practiced | When you last practiced each piece |
PDF files: If you imported a PDF (which displays as an image rather than interactive notation), only practice time is tracked. Accuracy metrics require MusicXML format where notes can be detected.
3 The Overview Screen
The main statistics screen shows your overall practice activity, organized into sections:
Your Progress
Always shows current, unfiltered data:
- Streak — Consecutive days with at least one minute of practice
- Weekly Pattern — Dots showing which days this week you practiced
- Weekly Goal — Your target vs. actual days practiced
- Calendar Heatmap — 12-month view with color intensity by practice amount
Time Breakdown
Filtered by time period (Today, Week, Month, All Time):
- Total Time — Combined practice duration
- Session Count — Number of practice sessions
- Practice Bar Chart — Daily or monthly time breakdown
- Mode Breakdown — Doughnut chart showing Right/Left/Both distribution
Recent Sessions
A list of your most recent practice sessions, showing the piece title, date, duration, mode, and accuracy.
4 Charts Explained
Crescendo uses several chart types to visualize your progress:
Practice Time Bar Chart
Shows how much you practiced each day (or month, for "All Time" view). Taller bars mean more practice time. The current day or month is highlighted.
Tap any bar to see the exact duration.
Mode Breakdown Doughnut
Shows the distribution of practice time across hand modes:
Accuracy Trend Line Chart
Shows how your accuracy has changed over your last 30 sessions for a piece. Separate lines for each hand mode help you see where you're improving.
Only shown for pieces with MusicXML format (not PDFs).
Calendar Heatmap
A 12-month grid showing every day of the year. Darker colors indicate more practice time that day:
- No color: No practice
- Light: Under 15 minutes
- Medium: 15-60 minutes
- Dark: Over 60 minutes
5 Setting a Weekly Goal
The weekly goal helps you build consistent practice habits. By default, the goal is set to 4 days per week, but you can customize it.
How It Works
The goal tracks unique days you practice, not total sessions. If you practice three times on Monday, that still counts as one day toward your goal.
Changing Your Goal
Tap the edit icon next to the weekly goal card to change your target. You can set any number from 1 to 7 days per week.
Start achievable: If you're just starting out, set a modest goal like 3 or 4 days. Hitting your goal consistently builds momentum and motivation. You can always increase it later.
6 Per-Piece Statistics
When viewing stats for a specific piece, you get additional detail:
Metrics Grid
Shows total time, session count, average accuracy, best accuracy, and when you last practiced.
Learning Phase
For MusicXML pieces, a badge shows your current phase:
- Learning — Still working through most of the piece
- Consolidation — Making progress, solidifying sections
- Maintenance — Most of the piece is comfortable; keep it polished
Session History
A paginated list of every session you've had with this piece. Shows date, duration, mode (with colored badge), and accuracy percentage.
7 Managing Your Data
You have control over your practice data:
Delete Individual Sessions
In the session list, swipe left on any session and confirm to delete it. This removes that single session from your history.
Reset Statistics for a Piece
At the bottom of a piece's stats page, tap the red "Reset Statistics" button. This permanently deletes all practice data for that piece—useful if you want a fresh start.
Deletions are permanent: There's no way to recover deleted sessions or reset statistics. A confirmation dialog appears before any deletion.
Making the Most of Your Statistics
Focus on consistency, not perfection
Research shows that practicing regularly matters more than practicing for long periods. A 15-minute session every day is more effective than a single 2-hour session once a week.
Use the streak and weekly goal features to build consistent habits rather than obsessing over accuracy percentages.
Use mode breakdown to balance your practice
The mode breakdown chart shows how much time you spend on each hand. If you notice you're mostly practicing "Both Hands" mode, consider spending more time with hands separate to solidify tricky passages.
See Hand Separation for tips on effective hand-separate practice.
Don't be discouraged by accuracy dips
Accuracy naturally fluctuates. It's normal to see lower accuracy when you're learning new sections, increasing tempo, or returning to a piece after a break.
Look at the trend over time rather than any single session. Steady improvement over weeks matters more than daily perfection.
Use the calendar heatmap to spot gaps
The heatmap makes it easy to see patterns in your practice. Notice large gaps? That's natural during busy periods. The visualization helps you recognize when you might need to rebuild momentum after a break.
Troubleshooting
My practice session wasn't recorded
Sessions are saved when you exit practice mode. If you force-close the app during practice, the session may not be recorded. Make sure to exit practice mode normally (tap the back arrow or home button) before closing the app.
Very short sessions (under a minute) may also not appear in statistics.
I don't see accuracy for my piece
Accuracy tracking requires MusicXML format (where notes can be detected). If you imported a PDF, the app displays it as an image and can only track time, not accuracy. For full statistics, import MusicXML, MXL, MIDI, or LilyPond files instead.
My streak reset unexpectedly
Streaks count consecutive days where you practiced at least one minute. If you miss a day entirely, the streak resets to zero.
The streak is calculated based on your device's local time zone. If you practiced late at night and it was after midnight, that may have counted as the next day.
Statistics disappeared after reinstalling
Practice statistics are stored locally on your device. If you uninstall the app, all statistics are deleted. Currently, there's no cloud sync for practice data. Consider exporting a backup before uninstalling.
