this is a solid use case because spoilers are a real problem and people do care about exact timing especially across timezones the real time countdown is a nice touch since thats more actionable than just a date id focus on accuracy and trust more than features if the timing is ever off users will drop it quickly also local timezone handling needs to be bulletproof smart alerts could be the real retention driver especially if they are reliable and not spammy maybe also add a simple watch tracking or seen status so it becomes something people check regularly not just once
yeah honestly a big chunk of most projects is glue code youre not imagining it a lot of real engineering is just stitching systems together reliably rather than building something novel every time i usually try to standardize patterns instead of rewriting from scratch like having small reusable modules for auth retries api clients etc so its not zero effort but also not reinventing everything tools help early but long term you still need to understand what theyre doing underneath or youll hit limits fast its kind of the unglamorous part of the job but also where a lot of real value sits making things actually work together cleanly and reliably
