Stop your morning alarm. That’s all it takes to let someone know: “I’m okay.” UOK turns a simple daily habit—stopping your alarm—into an effortless safety check-in. If the alarm isn’t stopped, a “Not Confirmed” alert is automatically sent to the person you chose in advance. UOK is built around two principles: simple and non-invasive. It does not require always-on GPS sharing, and it’s designed to deliver reassurance without tracking your daily life. How it works (3 steps) 1 Set an alarm (your usual wake-up time is fine) 2 Add people who check in on you (family, friends, coworkers, etc.) 3 Each morning, just stop the alarm • Stopped = “I’m okay” signal • Not stopped = “Not Confirmed” notification What you can do • Daily safety check-in via alarm dismissal (easy to keep up) • Not Confirmed alerts sent automatically if the alarm isn’t stopped • Your check-in circle can be anyone (not limited to family) • No always-on location sharing (privacy-first, avoids the feeling of being watched) • Connect via a shared link (send through any messaging app) Recommended for • People living alone who feel that “daily messages” to family or close friends are a burden • Anyone worried about a parent or loved one, but who wants to avoid surveillance-style monitoring • Those who want a system for peace of mind—without extra effort Pricing • Free to use (with ads) • Ad-free subscription: JPY 120/month or JPY 1,080/year (auto-renewing) ■ Subscription & Disclaimer A subscription is required to remove ads and extend the number of follow users to 30.

Verdict
The clearest difference is update cadence: UOK at weekly against Review Notebook 2's every 2 months. Review Notebook 2's advantage is device support (3 vs 1) and iOS requirement (10.0 vs 16.6). On price, ads and in-app purchases there is nothing between them.
