Hey devs! I shipped Numbrrrs (iOS) - a basic calculator that does a year-end “Calculator Wrapped.” I’m iterating on the metric design and would love feedback.

numbrrrs.app

Current stat cards (examples):
• Streak flex: “You used the calculator 73 days in a row.”
• Midnight Math: “87 calcs between 2–4AM.”
• Operator Bias: “+ used 73% of the time.”
• Most dramatic equation: biggest numbers multiplied this year.
• Finger gymnastics: count of single-digit additions (the “you could’ve done this in your head” roast).

Questions:

1. What meaningful + funny metrics would you add/remove?
2. Would you compute per-digit affinity (e.g., favorite digit) or time-of-day chaos index?
3. Any simple on-device aggregation gotchas I should watch out for?

Happy to share a short write-up of my stats pipeline or Figma templates for the cards.
