- [Case study: An alarm that rings through Silent Mode](https://necatidogrul.dev/work/wakora.en.md): The notification-based alarm went quiet under Focus. A system-level alarm with protected background audio that keeps ringing until the task is done; then a trademark dispute and a rename.
- [Case study: A photo can't see the oil](https://necatidogrul.dev/work/kaloro.en.md): Vision models undercount home cooking by 20 to 50 percent. The fix is not a better model but an interface that shows its assumptions and lets you correct them in one tap: cooking-oil and portion chips.
- [Case study: An honest range, not a prediction](https://necatidogrul.dev/work/ebb.en.md): Perimenopause does not keep a schedule; period apps print a date anyway. Ebb shows a range, models HRT with dose and site rotation, and found the cause of zero installs in a screenshot.
- [Note: Why photo calorie counting runs 40 percent low, and the chip fix](https://necatidogrul.dev/notes/photo-calorie-undercount.en.md): A vision model cannot see oil or plate size. A bigger model is not the cure; an interface that shows its assumptions and lets you fix them in one tap is.
- [Note: A .md twin for every page, and llms.txt: a site for AI engines](https://necatidogrul.dev/notes/markdown-twins-llms-txt.en.md): Google, ChatGPT and Perplexity read the same page differently. The method I put on eight sites: a Markdown twin of every page, one llms.txt, and schema generated from the same data. What it does, and what it does not.
- [Note: How an alarm app rings through Silent Mode](https://necatidogrul.dev/notes/alarm-silent-mode.en.md): A local notification is not an alarm. Ringing through Silent Mode and Focus takes an owned audio session, a layered fallback, and an honest "scheduling was interrupted" warning.
- [Note: Agent loops: plan, tool, verify, repeat](https://necatidogrul.dev/notes/agent-loops.en.md): Whether an AI agent works is decided by the loop, not the model. What I learned about loop design shipping ten apps solo and writing DevDNA.
- [Note: App Store rejection lessons from ten apps](https://necatidogrul.dev/notes/app-store-rejections.en.md): 3.1.2, 2.1, 4.3 and the cart lock. Most rejections live in metadata, not code; you get one appeal per submission, so build the gate before you submit.
- [Note: Why revenue shows zero in RevenueCat observer mode](https://necatidogrul.dev/notes/revenuecat-observer-mode.en.md): With StoreKit 2 in observer mode, purchases never appear unless you call recordPurchase. Notes from a bug I chased for a week thinking revenue was zero.
