App strategy is simple yet powerful toolbox with many tools in it which helps us customize our own solution as per requirement of any business need without spending much time at front-end development stage or configuration phase itself. It's easy to use but not so user friendly UI/UX if you are newbie who has no prior experience using this platform can be bit difficult sometimes just because its complex application structure or API integration point etc.. But once u know how things works then everything will come naturally otherwise also I am sure that one can get most out of their investment by reading documentation thoroughly before implementing anything. We used few other products previously like MS Excel automation engine where we had more control over code writing part. Using APS was good decision since now we have very less dependency on those third party applications instead we rely only on open source technologies.
