Modalissimo Ear Training vs EPA 608 Study Guide

Train your ear like a real musician. Intervals, chords, rhythm, dictation: with Modalissimo you finally hear music from the inside. Exercises designed and reviewed with singer June. Most ear-training apps make you guess isolated sounds. Modalissimo makes you hear them in context, like real music: every exercise starts with a cadence that sets the key. Your ear learns the function of every note — and that's what makes the difference in rehearsal, on stage or when improvising. ■ WHY IT WORKS • Tonal context before every question: a solid relative pitch you can actually use • Adaptive practice: what you miss comes back more often, what you master fades out • 5 minutes a day is enough: daily goal, streaks, levels and XP keep you going • Statistics per interval, chord and degree: see exactly where to improve ■ EVERYTHING YOU NEED TO PROGRESS Melody: Intervals, Scales, Modes (jazz modes too), Melodic Dictation, Sight-singing, Singing (mic), Score Harmony: Chords (7ths, sus2/sus4, inversions), Progressions, Cadences, Polyphonic Dictation Rhythm: Rhythm Dictation, Rhythm Writing Tools: Tuner, Metronome (any time signature, tap tempo), Simple Piano, Studio Piano, Pocket Mode ■ SING — THE APP LISTENS Sight-singing and Score: sing with count-in, click and accompaniment. The mic rates your pitch and rhythm note by note, right on your device. ■ EVEN WITHOUT LOOKING Pocket Mode plays the questions and speaks the answers, screen locked. Perfect on the bus or on a walk. ■ WHO IS IT FOR? Music students, singers and choir members, jazz and pop musicians, teachers (free teacher license), and anyone who wants to play and sing more in tune. ■ COMFORT • 8 timbres: piano, Rhodes, violin, sax, trumpet, flute, guitar, synth • Do Re Mi or C D E notation • 3 levels per exercise, from beginner to advanced • Larger layout on iPad, 9 languages, works offline, no ads ■ FREE TO START Every exercise is free, with 6 questions per day per exercise. Go Pro for unlimited practice on every exercise, no ads, forever: monthly, yearly or lifetime. And this is just the beginning: June is already preparing what comes next. ■ PRIVACY No account.

Pass the EPA 608 by knowing the numbers, dates and rules the test actually asks — the evacuation levels, the leak-rate triggers, the recovery percentages, the safety limits — instead of rereading a manual. EPA 608 Study Guide is a focused, fully offline companion for the EPA Section 608 Technician Certification exam, the federal credential every HVAC/R technician needs to buy and handle refrigerant. The app is organized exactly like the test: the Core section every candidate must pass, plus Type I (small appliances), Type II (high-pressure appliances) and Type III (low-pressure appliances) — pass all three and you're Universal. Study one Type or all of them. SIX WAYS TO STUDY • Flashcards — tap to reveal, tagged by test section • Multiple-choice questions set in real service scenarios — a rooftop unit, a walk-in cooler, a chiller room, a domestic refrigerator — every one with a worked explanation • True/false drills built from the misconceptions that cost marks • Term-matching game — pair key terms in rounds of five • Searchable glossary of the vocabulary the exam assumes you know • Key numbers & dates reference — every vacuum level, percentage, pressure limit and effective date, each with what it applies to and the trap to avoid WHAT'S COVERED • Core — ozone depletion and the refrigerant families, the Montreal Protocol and Clean Air Act, the Section 608 rules (venting prohibition, technician certification, sales restriction, recovery equipment, disposal, recordkeeping, penalties), substitute refrigerants and oils, refrigeration basics and the PT chart, the Three R's, recovery techniques, dehydration and evacuation, safety and shipping • Type I — small appliances: the 5-pound definition, recovery requirements with an operating or non-operating compressor, system-dependent versus self-contained equipment, access valves, refrigerant identification • Type II — high-pressure appliances: leak detection, the leak-repair rules and leak-rate calculation, the required evacuation levels, recovery techniques, refrigerant identification, hermetic compressor safety • Type III — low-pressure appliances: chillers under vacuum, purge units, leak testing without exceeding the rupture-disc limit, recovery to 25 mm Hg with heated oil, charging vapor-first, ASHRAE 15 machinery-room requirements CURRENT FOR TODAY'S FIELD The Section 608 rules are taught as the exam tests them, and the AIM Act changes technicians now work under — the HFC phasedown, A2L refrigerants like R-32 and R-454B, and the January 2026 HFC leak-repair rule — are covered as clearly labelled companion facts, never blended into the exam numbers.
