RoomScore – Measure conference room acoustics with iPhone Lidar
LiDAR + RT60 physics for meeting rooms, but AV consultants already solve this.

Tracks alcohol by ABV and size, but generic drink counters already handle this.
iPhone users who want to monitor alcohol intake without judgment or recovery focus

I like to track my drinkng, but the idea of "one drink" in a world where beer varies be tween 4.5 and 8% seemed weird. Also, a lot of existing drink trackers are (understandably) aimed at people who want to stop drinking.
Anyways, I made an iPhone app to fix these things. Free for five different drinks, one-time in app purchase to unlock unlimited, plus a few other features.
I actually hand-coded a version of this years ago; this version is pointing LLM's at that codebase and guiding it through the iOS 26 rewrite.

It turns screen time into a hydration gate: apps stay locked until the phone detects a face, a container, and a drinking gesture for about 15 seconds. Doing all inference on-device and using Apple's Screen Time APIs with no accounts or uploads is the genuinely smart part — it's an unusual, privacy-minded technical prank that actually solves the stated problem. Reliability in varied lighting/angles and easy workarounds will decide whether it's clever or just cute, but the engineering is impressive.
LLM cost calculator with current pricing, but spreadsheets and existing tools already do this.
Glass metaphor makes water inequality visceral, but static data viz without interaction depth.
One-click batch export and mobile-friendly UI, but removes.bg and Figma already dominate screenshot tooling.
Focused on one job: set intake goals, fire timed reminders, and track quick pours — all on-device with a tiny 3.2 MB binary and a no-data-collection claim. It looks clean and feels lightweight, but there’s nothing here that meaningfully differentiates it from the dozen similar single-purpose water apps on every platform.
