DiwaliLight is a respectful planning companion for Diwali week. Choose a region, follow a countdown, organize preparation tasks, draft greetings, browse original decor ideas, and review source notes for bundled date records. The app is built for families and communities whose dates, names, and customs may vary. Regional content is clearly marked as draft material pending native reviewer sign-off, and the Sources tab keeps citations visible so you can compare with your own family or community calendar. Features: - Countdown to the next bundled Diwali day - Preparation checklist for home, lamps, gifts, sweets, and greetings - Editable greeting drafts with a free starter set - Original decor ideas with safety notes where relevant - Regional date notes and reviewer-needed labels - Local reminders requested only when you choose to enable one - Offline storage with no account, analytics, ads, tracking, or cloud sync Premium is a one-time purchase that unlocks unlimited greeting drafts plus the full greeting template and decor idea libraries. DiwaliLight is not a religious authority. It does not provide ritual instruction, generate mantras or sacred text, predict outcomes, or certify dates as final for every community. Please follow your family or community practice.
Custos

One forgotten subscription at $12 a month is $144 a year that nobody decided to spend. It is almost never the price that catches you out β it is the date. Contracts renew on their own, and the notice period expires weeks before the charge. By the time the line shows up on your statement, it is already too late. Custos watches that date. Not the payment date β the one before it, the only one you can still act on. Free, no account, no ads. YOUR SUBSCRIPTIONS ARE NOBODY ELSE'S BUSINESS Custos has no server. Your data stays on your devices and, if you turn syncing on, in your private iCloud space β which we cannot access. The app's only network traffic goes to Apple's own services. WHAT CUSTOS DOES β’ Warns you on the right day β The cancellation deadline, worked out from the notice period and the next payment. A notification on the exact day, plus calendar reminders at 1 month, 15 days, 7 days, 1 day and the day itself. β’ Tells you what it all costs β Adjusted monthly and yearly cost, whatever the billing cycle, and a breakdown by category. β’ Spots free trials β "Free untilβ¦" while the first payment is still ahead. A trial never inflates your monthly cost, but it does trigger the alert: that is where it has to stop you. β’ Writes the letter for you β Email or registered letter, ready to copy, with your details already filled in. β’ Keeps the proof β Date sent, channel, reference, acknowledgement. Something to point to if you get charged anyway. β’ Catches silent price rises β Three dollars more goes unnoticed; Custos works out what it costs over a year. β’ Reads your bank statement β Drop in a CSV or OFX file: Custos spots the recurring debits and suggests the subscriptions behind them. The file is read on your device, with no connection to your bank, and nothing is saved until you confirm. β’ Shows what is about to leave your account β This month's outgoings, split by account, and a day-by-day schedule. β’ Knows who pays for what β Bank accounts and subscribers, for a household or a small team. β’ Explains it all β Twelve illustrated chapters inside the app, on Custos and on cancellation notice periods. β’ Lets you leave β CSV export and a full backup, whenever you want. ON IPHONE, IPAD AND APPLE WATCH β’ Home Screen widgets in three sizes, and Lock Screen widgets. β’ Live Activity β The countdown to your next deadline on the Lock Screen and in the Dynamic Island. β’ Apple Watch β The watch app and its "Cancellation deadline" complication. β’ Siri and Shortcuts β Ask out loud for your deadlines over the next 30 days. β’ On iPad β The list and the details side by side, with the handbook in the left column. β’ Full Dark Mode, Dynamic Type and VoiceOver. β’ Optional iCloud sync with the Mac. Install Custos, enter your subscriptions once, and let it watch the dates for you.

Verdict
The clearest difference is in-app purchases: Custos at none against DiwaliLight's 1. Custos also leads on device support (4 vs 2). DiwaliLight's advantage is iOS requirement (17.0 vs 26.0). On price and ads there is nothing between them.
