FAQ
A few things before you start
Is BanBan just for couples?
BanBan is built around life as a couple, with personal and group ledgers too. Use separate ledgers for your spending, shared bills, trips with friends or roommate costs. You are not limited to two people.
Can iPhone and Android users share a ledger?
Yes. Join the same shared ledger with an invite code to record and sync income and expenses, even when members use different phone systems.
How do splitting and settlement work?
Two-person ledgers offer equal splits, custom ratios or exact amounts. Groups support multiple payers and equal or custom-amount splits. Smart settlement previews offsets and suggested transfers before you confirm actual payment. BanBan never makes payments or transfers for you.
Do cross-ledger insights require duplicate entries?
No. Select ledgers using the same currency unit to review them together, and merge same-name categories if you wish. Analysis uses existing records; it does not add copies to other ledgers.
Can assets link to different ledgers?
Personal assets can link to payment methods across ledgers. Related entries update asset records according to your settings. Shared assets belong to their designated ledger. There is no bank connection or automatic currency conversion.
Can other members see my private entries?
Entries marked visible only to you remain protected by their privacy settings. Sharing a ledger or using cross-ledger analysis does not make them visible to other members.
What else can I organize?
Budgets, recurring entries, savings goals, shared calendars, anniversaries and home screen widgets. On iPhone, V2 Shortcuts can prepare pending entries; you check the destination ledger and details before posting them.
Is everything free?
BanBan is free to download. Some advanced features require membership benefits. Check the membership page in the app for features, sharing eligibility and pricing.
