hey! it's ayden
(the guy who made synapse)
it was summer break and i wanted to try creating an app just for a fun side project.
but i realised going from one platform to another, switching accounts and posting individually on each platform takes WAY too much time.
not only that, every time i tried making a thumbnail or templates, i had to open things like canva, a random background remover website, edit it with filters and what not using my phone then send it to my computer. things were messy.
also, online tools are really REALLY expensive. other platforms that post to multiple platforms cost $50/month and canva pro costs $15/month, and those tools are not very user-friendly...
i needed an all-in-one tool, somewhere i can post all at once, somewhere i can use tools that would've otherwise taken me 30 minutes to find. something compact and extremely easy to use. so i built it myself, and that's how synapse was born.
although this website and service is relatively new, i will be sure to use synapse to help market and post things regarding my future apps that i develop, perhaps synapse can help you too!
if you are looking to save hours of social media work every week, try synapse!
any feedback, i can promise that you will be heard and i will be putting my absolute best into making sure this app will serve your needs and benefit you. try it for free! just click the button below.
