Support
Happy to help. Email abduvohid1996@gmail.com and a real person will reply — DueFlow is made by one developer, so please allow a couple of days.
Reporting a problem? It would help a lot if you could include your iPhone model, your iOS version, and the DueFlow version shown in Settings. If you can remember what you were doing just beforehand, that detail is often the whole answer.
Reminders
A reminder didn't arrive
Sorry about that — it is usually one of three things, and they are quick to check:
- Reminders are switched on in DueFlow. Settings → Notifications → Due date reminders.
- iOS is allowing them through. iOS Settings → Notifications → DueFlow. If alerts were declined the first time they were offered, this is where to allow them.
- The cost has reminder days set. Open the cost and check its reminder offsets — 7, 3, 1 or 0 days before. A cost with none chosen won't notify you.
Why do reminders stop if I don't open the app for a long time?
DueFlow has no server, so reminders are scheduled ahead of time on your phone and iOS delivers them. iOS limits how many notifications can be queued at once, so the app schedules as far ahead as that limit allows and tops the queue up each time you open it — including when you open it by tapping a reminder.
How far ahead that reaches depends on how many costs you have and how many reminder days each one uses. With a handful of costs it is many months; with twenty costs on all four offsets it is a few weeks. Whenever the limit is what decides, Settings tells you the date your reminders currently reach, so it is never a mystery.
Can I change the time reminders arrive?
Yes — Settings → Notifications → Reminder time. It applies to all of them.
Costs and dates
I can't find a cost that's due later in the year
The home screen shows this month and next, so it stays quick to read at a glance. Everything else is one tap away behind the list icon in the top right: All costs shows every cost you have, whatever its date.
A cost is billed on the 31st. What happens in February?
It appears on the last day of February and returns to the 31st the following month. DueFlow remembers the real billing day rather than the last date it displayed, so a month-end cost won't drift earlier over time.
What does swiping to mark paid do?
It moves that cost on to its next due date. Rows that are due today or overdue can be swiped. There's no undo yet — it's on the list — so if you catch it straight away, open the cost and set the date back by hand.
Can I pause something I've cancelled?
Yes, and it's usually better than deleting. Open the cost and pause it: it stops appearing in your upcoming charges and stops sending reminders, but stays in All costs with a Resume button whenever you want it back.
Backups and new phones
How do I back up my data?
Settings → Your data → Export a backup. That writes a JSON file and opens the share sheet, so you can keep it in Files, iCloud Drive, or send it to yourself. It contains every cost and your settings.
How do I move to a new phone?
Export a backup on the old phone and save it somewhere the new one can reach — iCloud Drive is usually easiest. Install DueFlow on the new phone, then Settings → Your data → Restore from a backup and choose the file.
What's the difference between Merge and Replace?
Replace clears what is on the phone and restores the backup exactly, which is what you want on a new device. Merge keeps what is already there and adds anything the backup has that the phone doesn't. Merge won't overwrite a cost you edited more recently than the backup, and restoring the same file twice won't duplicate anything, so it's safe to try.
I deleted the app. Can I get my costs back?
Only from a backup file exported before deleting, unfortunately. Nothing is stored on a server, so there's no copy on our side to restore from. If you did export one, reinstall DueFlow and restore it and you should be back where you were.
Money and currencies
Can I mix currencies?
Yes. Each cost keeps the currency you actually pay in, and DueFlow totals each one separately. It won't convert between them or apply an exchange rate, since a total that mixes currencies at yesterday's rate isn't a number you can really act on.
Does DueFlow connect to my bank?
No — and there are no plans to. There's no bank login, no card details and no payment processing anywhere in the app. You enter what you pay, and DueFlow tells you when it is next due.
Privacy
What does the app collect?
Nothing about your costs ever leaves your phone. The app does record three anonymous events — app opened, cost added, marked paid — so we can tell whether it is being useful. The privacy policy sets out exactly what those contain, which is very little.
Can I opt out of that?
Of course. Settings → Privacy → Share anonymous usage data. Everything else in the app carries on working exactly as before.
The app itself
Is it really free?
Yes — unlimited costs, no ads, no paywall and no in-app purchases. Features that ship free stay free.
Is there an Android version?
Not yet, though it is planned. If it would be useful to you, do say — knowing there's demand genuinely helps it move up the list.
Can I suggest a feature?
Please do. The email above reaches the person who writes the app, and suggestions from people actually using it are the most useful thing that lands in that inbox.
