About

NxN Browser

Read full description

An independently developed web browser app I created it because existing browsers were difficult to use. Major companies all provide browsers, but I will continue improving this app with the goal of creating an experience that cannot be found in any of them. - Gesture features γ€€Reload, new tab, close, restore, back, and forward. Once you get used to them, they become indispensable. - Tab group feature γ€€Every browser can manage tabs, but tab groups are not very common, are they? γ€€You can switch between many open tabs while still viewing the web page. γ€€There is also a tab group screen where you can view multiple tab groups at the same time, so even your tab groups can be checked at a glance. - Full-screen display γ€€Full-screen display is available in many browsers, but this app allows detailed setting changes, such as keeping the URL bar visible. - Settings screen γ€€Since everyone uses browsers differently, I have made it possible to adjust a wide range of detailed settings.

About

Allergy Diary

Features
Read full description

Record the severity of sneezing, runny nose, nasal congestion, itchy eyes, cough and skin rash, with notes. Edit daily entries and review symptom intensity on the calendar. The app interface is in Korean. Review trends, symptom distributions and weekday patterns from your entries. Copy a summary to discuss with a clinician. These statistics summarize self-reported records and do not diagnose an allergen or a condition. Symptoms vary between people; consult a doctor or pharmacist. The app does not recommend medication timing or doses. When pollen data is available, the app displays Korea Meteorological Administration predictions for a representative location in the selected Korean region, with the target date. These are not measurements or assessments of your personal allergy risk. Oak and pine data cover April through June; weed data covers August through October. Mugwort, dates outside the supported season, missing data and failed connections are shown as unverified, without a risk grade. Symptom recording remains available when pollen data cannot be provided. Enable reminders and allow device notification permission to receive a diary reminder at your chosen time. Pollen reminders ask you to check data in the app; they do not predict the next day's risk. No account is required. Record symptoms offline and keep entries on your device. The app is free to use, with no ads or tracking permission prompts. The iOS Home Screen widget shows whether you recorded today and your consecutive recording days.
