Before we built the coaching layer for GlucoCoachAI, we ran a benchmark.
OpenAI vs Claude vs DeepSeek. Same prompts. Same patient inputs. Compared on accuracy, latency, cost per call.
One won. We committed to it. The health stakes were real. Choosing a model by default was not an option.
Live on both stores since December 2025.
Picking an LLM is an engineering decision. It should be made with data.

Inherited a half-finished app? Check it for ghosts before you write any new code. Here are the 5 things we look at in week one.
Is there a real wall between staging and production? On iPermit, testing a change could break the live app.
Last ones: keys sitting in the code, and crashes that only happen on real phones. Dan Haiem's full triage (6 min): youtu.be/sUsTjVZheSI
Running the best LLM on every step of Echo Journal would have killed the unit economics before we had a business.
We tiered it instead.
Cheaper model: first-pass transcription cleanup. Best model: targeted deep analysis sections only.
Same outputs. Fraction of the cost per entry.
Tens of thousands of users. Tens of thousands in monthly revenue. The model you pick and when it runs are both decisions that affect whether the product can afford to operate.

Months in the React Native video stack. Every crash mode reproduced and resolved.
v2.0 shipped May 2026. Both stores at 4.3 stars.
Rio Wilson came to us with an app he did not build. He bought it. It crashed on init, mid-playback, and remount.
The previous team was gone. The code was ours to trace.
When we take over a stalled app, no new code gets written until the audit is done.
Add code on top of code you don't understand and you can't tell your bug from the last team's.

Our CEO Dan Haiem published a new article in Medium. Would love to hear your thoughts. Here's the link: medium.com/@dan_appmakersceo…
Three of the biggest threads in app dev this month:
"After 11 years in mobile development, where should I go next in the AI era?" r/FlutterDev
"Is it still worth learning app development?" r/androiddev
"AI writes better code than me. How do I keep my identity?" HN
These are real developers who are good at their craft asking whether it still counts. The ones doing well right now are using their judgment to direct AI, not competing with it.
