Tracking what you spent is only half of it. The question people actually ask is can I afford this? — so Blipko now runs a real budget behind every message.
Every expense is sorted into one of three buckets:

/status — where each bucket stands and how much you can safely spend per
day for the rest of the cycle./report — a monthly summary of where the money went.
Blipko can warn you as a bucket fills up. You pick the dosage — off, gentle, aggressive, or relentless — so it's a nudge, not nagging.

Nudges default to off. Turn them on from the bot's settings whenever you want them.
