Moon phases assist vs StrumBuddy

This app allows you to visually learn about the different phases of the moon depending on the positions of the moon, the Earth, and the Sun. The app has undergone a major overhaul to improve its features! Why does the moon have different phases? Why does the height of the Sun change depending on the season? These diagrams provide easy answers to these questions! You can intuitively grasp the positions of the Sun, the Earth, and the moon through overhead and celestial sphere diagrams! What are the positions of the Sun and the moon during a full moon? Where is the Sun when the waning crescent transits the meridian? You can answer these questions by turning the dial and checking their positions! ※The size and distance of celestial objects are not drawn to scale but exaggerated for easier understanding. ※For easier understanding, the Earth's orbit is made circular instead of elliptic while the inclination of the moon's orbit has been omitted.

Learn acoustic guitar five minutes a day — with a coach that actually listens. StrumBuddy uses your iPhone's mic to hear you play, then gives the kind of feedback a good teacher would: not just "right or wrong," but exactly which string buzzed, which note didn't ring, and which chord change is falling apart under tempo. Then it tells you the one thing to work on next. WHY STRUMBUDDY IS DIFFERENT • It listens. Play a real acoustic guitar — no tapping along to a screen. • Per-string feedback. See clean vs. muted vs. buzzing for every string, so you know precisely what to fix. • An adaptive coach. StrumBuddy tracks your individual skills, finds your weak spots, and shows its reasoning — "your C is fine; it's the change into it that needs work." • A 5-minute daily habit. One tap starts a short guided session that always ends on a win, with a streak to keep you going. WHAT'S INSIDE • Chord trainer with live, per-string cleanliness feedback • Chromatic tuner • Transition drills with a metronome to tighten your chord changes • A guided daily session picked for you by the coach • A skill path that grows as you do BUILT FOR BEGINNERS Most people who pick up a guitar quit within a few months. StrumBuddy is built to get you past that — small daily wins, clear next steps, and feedback that meets you where you are. PRIVATE BY DESIGN StrumBuddy processes audio on your device. No account, no tracking, nothing sent to a server. Grab your guitar and play. StrumBuddy is listening.
