A USSD code directory that works offline, for four countries.
01
Context
In every country, each mobile operator offers its internet bundles, Mobile Money services and balance checks through USSD codes. Touna gathers your operators' codes in a single app.
It covers Congo-Brazzaville, DR Congo, Gabon and Cameroon. Touna is an independent app: it is not affiliated with any operator.
02
The solution
Pick your country, tap a code, check it, and Touna dials it for you. The exact code is always shown before it is launched: the user decides.
Codes are sorted by category (internet, calls, SMS, Mobile Money, balance, services). Search is fast, including by voice, and the app handles dual SIM: the user chooses which SIM dials the code.
03
Works offline
Codes stay on the phone and update as soon as a network is available. Everything therefore also works offline, which matters where coverage is unreliable.
04
Compare and save
An internet bundle comparator across operators shows the best price for a given data volume and duration.
Reminders warn the user before a bundle expires so it can be renewed in one tap, and a spending tracker summarises what the launched codes cost.
05
Privacy and community
No PIN code is requested, displayed or stored. History, favorites, spending and the cart stay on the phone. Google sign-in is optional: it is only used to suggest, vote on or report a code. The account can be deleted at any time.
The community can suggest a missing code or report one that no longer works; every contribution is verified before it is published.
