Product summary
Review the store description, core capabilities, and common use cases.
Guppy helps real fans win scarce drops.
It watches Walmart + Pokémon Center for queues, restocks, and “action-needed” moments - then alerts you at the exact time you need to step in (captcha prompts, getting through the queue, inventory going live).
No doomscrolling Discord. No staring at a queue for hours. Just focus on the moments that matter.
WHAT GUPPY DOES
- Queue monitoring (Walmart + Pokémon Center)
Get notified when a queue starts, when you’re through, or when something changes.
