Signal in.
Beat out.

Record a sound, import one, or pick from 2,235 included. BreakBolt chops it across 16 pads and finds its key and tempo, so the pads are ready to play as soon as the sound loads.

A jungle tune in four moves. Every sound and screen is the app.

HOW IT WORKS

From one sound to a beat

The same four moves as the video, at 172 BPM, using the starter kit that ships with the app.

BreakBolt's PADS page: a waveform chopped into 16 slices above a 4 by 4 pad grid
01 · CHOPLoad a soundRecord, import, or pick from the library. It's sliced across 16 pads evenly, on the hits, or on the beat grid.
The ALL PADS grid: 16 rows of pads by 16 steps, with a jungle pattern lit in pink
02 · STEPBuild a patternSixteen steps per pad, or every pad in one grid. Swing, gate and velocity give it feel.
A pad's settings with the TRIM waveform cut down to its first 0.187 seconds
03 · FLIPResample and trimBounce the whole loop onto one pad, trim it by eye, pitch it, and play it again.
The MIX panel with distortion, filter, tempo-synced delay and reverb
04 · OUTMix and exportDistortion, filter, synced delay and reverb, then a WAV that loops cleanly, a live take, or a vertical video.

FEATURES

Everything in the app

All of it comes with the one price, including every sound pack.

Chop it three ways

Equal slices, slices on every hit, or slices on the detected tempo. Drag any cut by hand, zoomed in up to 8×.

It knows the key and tempo

Scale Lock keeps pitched pads in the sample's key. The detected BPM is one tap from becoming your tempo.

Every pad is an instrument

Pitch, stretch, reverse, volume, pan and a name for each of 64 pads. Trim one pad without moving its neighbours.

Timing on the audio clock

The sequencer is scheduled against the audio clock, so the beat stays in time while you scroll, switch apps or lock the phone.

Resample, then go again

Record one bar of everything playing, effects included, onto a pad and build the next layer on top.

2,235 sounds, all included

24 built in plus 72 packs of kicks, bass, percussion, melodic and FX, downloaded one pack at a time.

Learn it by using it

A 60-second walkthrough makes your first beat with you. A one-line tip explains each control the first time you touch it.

Exports that loop cleanly

A WAV exactly one bar long that loops in any DAW, a live take, or a vertical video for short-form posts.

iPhone and iPad

Every iPhone size, and on iPad an inspector beside the page in any orientation. Unlimited projects, 50 steps of undo.

THE PROMISES

Price, privacy and your work

Privacy

On your device

No sign-in, no analytics, no tracking. Recordings leave the phone only when you share them. Privacy policy.

Safety

Saved as you go

BETA

Help shape it on TestFlight

BreakBolt is in beta. Testers get the app free through Apple's TestFlight, try it for fifteen minutes, and tell us what confused them and what's missing. That feedback decides what gets built next.

Open the link on your iPhone or iPad. It installs TestFlight if you don't have it, then BreakBolt. Places are limited, so if the beta is full, check back for the next round.
