Upstream - Data Training
Less querying more questioning
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Stop building the wrong thing. Upstream trains data analysts to ask the right question before the query, one short real world case at a time.
Upstream is a thinking gym for data analysts. Instead of teaching SQL or dashboards, it trains the skill that matters most: knowing what to ask before you query.
HOW IT WORKS
You're dropped into realistic workplace scenarios — a stakeholder wants a "quick report," retention looks suspiciously good, or an A/B test shows no lift. Each case challenges you to think critically, ask better questions, and resist the urge to just pull the numbers.
Choose your approach at each step. Do you dig into the data immediately, or push back on the request? Challenge the metric definition, or accept it at face value? Every choice reveals how a real analyst would navigate the situation.

What's New in Upstream 1.4
We gave the home screen a fresh new look. Your stats, streaks, and skill progress now sit on clean frosted cards that are easier to read at a glance.
Clearer daily progress. The today counter now says cases today so you always know what it is tracking.
Plus the usual round of polish and stability improvements.
Thanks for using Upstream. Keep asking the right questions.
