OneVault

OneVault keeps everything in your life that happens on a date โ and tells you what needs you today. Insurance renewals. Medicine refills. Passport expiry. Property tax. The car service. Your sister's birthday. All of it in one place, sorted so the urgent thing is the biggest thing on screen. WHAT IT DOES Open the app and it answers one question: what needs my attention? Past due items come first and largest. This week next. Then this month, then later. Nothing else competes for your eye. Tap "Mark as done" and OneVault records what happened โ the date, the amount, a note, a receipt โ then moves the reminder forward one cycle automatically. Weekly, monthly, quarterly, half-yearly or yearly. Your history builds itself. NINE CATEGORIES, THREE GROUPS Recurring โ Insurance, Health, Bills & Subs Assets โ Gold & Jewelry, Electronics, Vehicles, Property Records โ Documents, Dates to Remember Each category has its own fields. Insurance asks for the policy number, cover and nominee. Health asks for dosage and hospital. Documents asks for the issuing authority. You can add your own categories too. NOTES, FOR THINGS WITHOUT DATES WiFi passwords. Blood groups. Locker combinations. Bank login hints. The stuff that never expires but that you can never find. Titles only on the list โ no preview line, because these hold passwords. REMINDERS THAT DON'T NAG Two notifications per item: one before it's due, one on the day. Set the lead time per item โ 60 days for a passport, 2 for a refill. Never a daily drumbeat on something overdue. WIDGETS Lock Screen and Home Screen widgets show the most urgent item at a glance, in four sizes. PRIVATE BY DESIGN Everything lives on your device and syncs through your own private iCloud account. No servers of ours. No accounts to create. No analytics. No tracking. Nobody sees your passport number, least of all us. Lock the whole app behind Face ID if you like. BUILT FOR IPHONE AND IPAD A focused single column on iPhone; a proper two-column layout on iPad. Full Dark Mode. Text scales with your system size setting. PRICING 30 days free, with everything working. After that, you keep full use of everything you've already added โ marking things done, editing, attaching files, reminders, search, all of it. Adding new items needs a one-time purchase. No subscription. Ever.

Verdict
The clearest difference is in-app purchases: Notes Den at none against OneVault's 1. Notes Den also leads on iOS requirement (16.4 vs 18.0). OneVault's advantage is update cadence (daily vs fortnightly). On price, ads and device support there is nothing between them.
