Here you don't tap a button labelled C#. You play the note. That is not a cosmetic detail. Picking the right answer out of twelve is a quiz. Finding the note on a keyboard is an act — the same act a musician performs, with the same uncertainty and the same payoff when it lands. FOUR WAYS TO TRAIN 1 note — hear a note, play it back. The original app's mode, unchanged in spirit. 3 notes — hear a sequence, play it back in order. Run and record in the header, exactly as they were. Ear — which note was that? Between questions a few seconds of unrelated tones play, so the previous note is not still sitting in memory and the answer has to come from recognition rather than from comparison. It is uncomfortable, and that is the entire point. Note Rain — notes fall toward the keyboard. Play the piece in time, build a run, and hear the accompaniment grow with the multiplier. See the notes, or switch them off and find them by ear. DAILY PITCH One puzzle a day, the same for everyone, three notes and five guesses. A grid to share when you solve it. No account, no nagging notifications. TWELVE LIGHTS Your progress is twelve lights, one per note. They come on when a note is reliable, and they never go out — nothing decays because you were away for a week. HONEST ABOUT WHAT THIS IS Absolute pitch in adults is contested. In published training studies roughly one in five to one in three committed adults reached criterion, and the average was about seven of twelve pitch classes after some twenty-one hours of practice. This app does not promise more than that. What it does promise is that the training is built on what was actually measured: masked intervals, feedback half a second after the answer, and pitch class rather than pitch height. TWENTY-ONE LANGUAGES, AND YOUR COUNTRY'S SONGS FIRST The interface comes in twenty-one languages and switches with one tap inside the app, not three screens deep in Settings. Note naming is a separate choice: H or B, do-re-mi or C-D-E. And the Note Rain repertoire follows your language, so the tunes you grew up with are at the top of the list. NO SUBSCRIPTION, NO CURRENCY Every mode, the whole daily puzzle, all languages and all accessibility are included. No subscription, no currency, no lives to buy, nothing that disappears if you stop playing. BUILT TO BE PLAYED Landscape on iPhone, because seven white keys in portrait put the black keys under Apple's 44-point floor. Real piano geometry — the black keys are not evenly spaced, because they are not on a piano. Polyphonic, so two fingers give two notes. VoiceOver on every key. H or B, do-re-mi or C-D-E: four naming systems, because in Sweden the note is called H and an app that says B has taught the wrong name for two notes out of twelve.

DOOM LOOP is a stem-based loop machine built from the Doom Cougar catalog. Seven channels — kick, bass, snare, hats, acid, perc, and FX — each loaded with eight loops pulled from real Doom Cougar tracks. Tap a pad to bring that loop in. Tap another to swap it out on the next bar. Everything stays at 138 BPM. Everything stays in time. There is no beat-matching, no syncing, no waveforms to wrestle with. The tempo is fixed. The bars are fixed. The loops swap clean. WHAT'S IN IT - 56 loops from the Doom Cougar catalog — Crease, Creature, Hematoma, Mothers Milk, Parlor Floor, Savage Wit, Shag Chain, Yule, and more - 7 channels — one loop at a time per channel, plus a one-shot FX channel for stabs and vocal hits - 138 BPM master tempo with every stem pitched to match - 3-band EQ on every channel — low, mid, high - Independent volume on every channel - Per-channel lock — protect a loop you like before randomizing - Random — roll the dice on every unlocked channel, queued to the next bar - Bar / beat indicator with 4-LED beat readout HOW IT WORKS Tap a pad to load that loop. If a channel is already playing, the new pick is queued — it swaps in clean on the next downbeat. No bumps. No dropouts. No drift. Lock the channels you want to keep. Randomize the rest. Walk a track from a stripped-down kick-and-acid groove into a full mix and back without touching the play button. This is Doom Cougar's catalog, taken apart and handed back to you. Build new tracks. Wreck old ones. Nothing here gets out of time. 138 BPM. 7 channels. 56 stems. One bar at a time.

Verdict
