Low FPS, Converting to another program

just finished my 1st app in construct 2, to be honest i like it a lot, coming from a flash developer, C2 is much easier and quicker to deploy. i made a beat sequencer app in just 1 week. Im not a coder, only knew a little action scripting, and programming in C2 blows my mind. But i'm really disappointed with the results. Although it runs flawlesly in desktop, the mobile version is super lagged! i mean talking about 60fps vs 10 fps (on a LG G3!), and i need consistent timing.

is there any way i can improve this? will using Delta Time (dt) fix it?
or can anyone suggest me any program / language to convert it to a proper app? (im thinking delphi)

Have you gone through the manual and tutorial entries on performance optimization for mobiles?

Avast just blocked your link saying it contains malware.

Make sure WebGL is enabled < yes
Avoid using too many objects or particles < how many is too many? 200?
Place objects using the same blend modes or effects on the same layer. > Yes
Avoid objects with large areas of transparency. < yes
Avoid large areas of overlap between objects. < this maybe the problem. i have some object sandwich with each other, but they are only menus. i wonder if it effects the overall performance.

no virus / malware in that link. please ignore warning.

You're just not going to get better than +or- 10 ms in C2.
You probably won't be able to get perfect timing in any engine that's v-synced, especially in mobile.

What exportation option are you using to test?

xdk CW = idle: 45fps, play : 10-15fps
cocoon io Canvas+ = idle 35fps, play 20fps

the only moving part is the playhead which in collusion with the active toggle. how many is too many?
i dont mind +- 10% as long as above 45fps at play.

@diontoradan what program are you going to move to? I was looking at unity+playmaker and it interests me.

Hm... How big are your images? Remember that what looks good on a big screen, really isn't gonna make a difference on a small screen.

@illfstudio : i was going to try unity + playmaker, but i really liked what i've made, maybe this is the starting point to start to learn real programming, so i want to know what the most suitable for this kinda app. i'm thinking delphi cuz FLstudio was build on it.

but if unity 2d is enough i think i will try unity
