DocTracker – track client documents and send reminders
Yet another document tracker, but the accountant niche is specific.

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.

Clever use of Apple Reminders as a cross-device trigger for local CLI agents.
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.
Full-screen break enforcement with skip cooldown—obvious idea, genuinely harder to ignore.
Break reminder app when Time Out and Stretchly already do this for free.
