Context: "Meal plan builder" in MealMind — reading last week against a base of 1,284 active users. It looks like a fix: people start, then drop before they finish. the flow leaks in the middle. What the data shows (Reached → Repeated): Reached: 82% (1,053 users) Started: 62% (796 users) Completed: 18% (231 users) Repeated: 9% (116 users) Step by step: Reached → Started: 76% continue, 257 drop off Started → Completed: 29% continue, 565 drop off Completed → Repeated: 50% continue, 115 drop off Where it leaks: 796 users reach "Started", but only 29% finish it — about 565 drop between Started and Completed. What I need — specific to this feature, not generic advice: 1. The 3 most likely causes of this drop, ranked by how probable they are. 2. The single smallest change to ship first, and why it should move the Started → Completed rate. 3. How to validate it: what to instrument and the Started → Completed rate lift to expect. 4. Two backup experiments if the first change doesn't land.
Top 3 priorities
See where you're losing people.
One clear read per feature — the exact step where people drop. No dashboard to decode.
The same four steps on every feature, so you stop guessing where people drop off.
How it works.
You've got a coding agent. Where's the data agent that tells it what to build next?
Sets itself up
Drop in the knowwhy agent. It reads your code and wires up tracking for every feature loop. No dashboards to define.
Diagnoses each feature
Get one clear read per feature: where users are reached, started, completed, and where the loop breaks.
Improves with data
Hand the clearest signal to your coding agent. knowwhy pairs it with your codebase, ships a fix, then re-measures.
More data won't tell you what to build. The next move will.
Most tools make you decide what to track and how to measure it. knowwhy reads the app you already shipped, learns your flows, and names the next move — no data background needed. Like a data analyst who already knows your product.
0dashboards to build
knowwhy reads your app and proposes what to track. No setup, no plumbing.
4steps scored on every feature
Reached, Started, Completed, Repeated — the same read, so features compare.

Common questions
- Do I need to be technical?
- You don't need to be a data person. If you got your app live, you've done the hard part. Plugging knowwhy in takes a few minutes, and I'll help.
- What does it cost?
- $9 a month for one app, locked for as long as you stay subscribed. You start with a 14-day free trial, and there's no card up front.
- What does it add to my app?
- It connects signals, scores each feature across Reached, Started, Completed, and Repeated, names the next move, and measures whether it worked. Every tracking change is yours to review and approve first.
- I already use Firebase, PostHog, or Amplitude.
- If those work for you, great. knowwhy is for makers who want the diagnosis and the next fix without building dashboards and tracking plans first.
- Do I have enough users?
- If a handful of people use your app (testers, first users, first subscribers), that's enough. If no one's using it yet, that's a different problem (getting users), and knowwhy can't help with that part.
- Is my data private?
- Yes. No ad tracking, and you approve every change before it ships. We can also help you think through App Store privacy questions, though it's not legal advice.
