Different products, built the same way.

  • Start with the phone people own

    A shopkeeper should not need a rented machine, and a visitor should not need a stack of guides. Both products run on an ordinary Android phone.

  • Speak the local language

    MerchantVoice talks in Hindi, English and Bengali. HoiHoi is rooted in one place and its food, festivals and streets.

  • Be plain about data

    Each product publishes what it collects, who processes it and how to delete it. We do not sell personal data.
