It is dirty and different. It is not sample based and comes with a handfull of effects.
The layout is to scroll from the top to the bottom, starting with the bass drum and ending with the effects section.
There is not many drum machines for Android based on synthesized drums so that makes this interesting but what makes it even more interesting is that there is no drum machine that sounds like it either.
Anyone interested in aggressive noisy sounds or chiptune should definitevely check this out.
Do think that it is also good to have anyway as it fun to tweak and just being different makes it an added possibility that is hard to get to with other apps.
There is a demo that is useful if you want to sit and record into a DAW for example the full version comes with preset saving and soon to come audio recording.
It is made using Pure Data and ported to Android using LibGDX which is the same as the developer working on Pure Data Party apps. It seems to be shortest way for someone that wants to make quality apps but do not have years to spend how to code properly...
The developer is also active musically and you can hear his music here:

Dragon - Synth Drum Machine
Dragon is a drum machine built to quickly and easily make glitch, distorted, lofi drum beats and manipulate them live. The drums are simple and flexible, capable of some classic drum machine sounds and also new weirdness. Each is synthesized in real time and sent to a multi effect rig with variable speed stutter, bit reduction, pitched feedback delay and a resonant bandpass filter. The drums are triggered by a four pattern step sequencer. Patterns can be changed individually for each drum or triggered together for quick pattern switches for all drums.
Features:
Four pattern sequencer with local and global pattern control
BPM control with nudging
Save/load presets
Three drum synths:
-Bass
-Snare
-Hi-hat
Effects rig:
-Asymmetry and tanh(x) for tape like distortion
-Pitched feedback delay
-Retrigger (aka stutter/buffer) with variable speed and reversing
-Bit reduction
-Down-sample
-Reverb
-Resonant bandpass filter
Preset management requires permission for file storage read/write (optional on Android M+)
Unpaid version disables preset saving and audio recording
Audio recording coming soon. Possible future ports to desktop and ios. Made with Pure Data and libGDX
Full parameter and effect reference:
SYNTH PARAMETERS
Bass drum-
Freq: Frequency. Locks into semitones so you an harmonize easily
Decay: Amplitude decay
Freq Env Dec: Frequency envelope decay. Changes how fast the pitch drops
Freq Env Amt: Frequency envelope amount. Changes how much the pitch drops
Snare drum-
Tone Low Dec: Tone low decay
Tone High Dec: Tone high decay
Noise Dec: Noise decay
FM: Frequency modulate the low tone by the high tone
Freq: Frequency. Locks into semitones so you an harmonize easily, though overtones from fm and the high tone bring inharmonic tones
Freq Env: Frequency envelope. Changes how much the pitch drops
Delay: Feedback delay
Delay ms: Milliseconds of delay
Hi-Hat-
Freq: Frequency
FM: Frequency modulate the tone
Tone Dec: Tone decay
Tone Amp: Tone amplitude
Noise Dec: Noise decay
Noise Amp: Tone amplitude
EFFECTS
Retrig: Loop audio by the specified time interval (1/2, 1/8, 1/16, 1/32 notes)
Rev: reverse retrigger’s playback
Speed: control the speed of the retrigger’s playback
Bit Red: Bit reducer. Mixes in a low bit signal
BP Filt: Band-pass filter. All the way left is off
Tanh: Amplifies and the waveshapes the signal through a hyperbolic tangent curve. Creates a tape-like distortion
Asym: Adds to the signal, creating a DC offset. Doesn’t do much unless you have Tanh turned a bit
Down Samp: Down-sample the signal
Reverb: Mixes in reverb signal
Delay: Pitched feedback delay dry/wet
Delay ms: Milliseconds of delay
Freq: Adjust the pitch that the delayed signal is adjusted by. Also locks into semitones
