A few words about Android

Android is a widely used OS and together with its ecosystem a massive distribution of technology. What makes Android great is its openess, offering unlimited options for customization.  Android openess and footprint is very appealing for individuals and companies to develop applications and offer diversity. The diversity of solutions exploded the Android ecosystem as many users are thrilled to use countless solutions that solve real problems or offer recreation.

The many different options are welcome to the most of the users but seem chaotic to others. Users new to Android face difficulties to use Android phones, especially users with physical and mental limitations like seniors have a slow learning curve. For these users who need harmonious unified interfaces Katsuna is the subtle base needed for exploration of all the different apps.

Inclusivity on Android  

The majority of mobile solutions are designed for a young audience without physical limitations. There are plenty mobile solutions which people with additional needs and especially seniors struggle to utilize. Android as the major mobile platform is affected by this phainomenon.

Ignoring people needs breeds exclusion: exclusion breeds isolation; isolation breeds insecurity; insecurity breeds fear. There is a need to invite people with diverse needs. There is a need to be inclusive.

Katsuna ROM amplifies the Android offering by simplifying the user experience

At Katsuna we rethink Android and we optimize it for seniors. Katsuna ROM consolidates a number of changes and brings a tailored optimal experience across the operating system interfaces and a portofolio of basic apps. With Katsuna ROM as a base the Android world becomes accessible for seniors.

Smoother Android experience

We design and port a number of solutions to the Katsuna ROM based on Android 8.1 . The systematic application helps seniors to face their challenges. Moreover the coherency of the interfaces and the common logic behind similar interactions make the Katsuna ROM smooth and consistent. Below we describe shortly the areas we changed the AOSP code for improving the experience for older users.

The possible customization of an Android OS has a very wide scope. At Katsuna, we are based on AOSP and we are performing changes that have user impact on System Apps, on the Java API Framework and we are also delivering on top an ecosystem of apps. For the scope on lower layers we rely and endorse the incredible good work already done on Android. Katsuna thanks anyone who contributed to Android and produced software so that we are able to build products on top. We also thank Opera Software for allowing us to distribute the Opera for Android browser.

Benefits

Katsuna Android customization is the catalyst for enabling more seniors to Android. The majority of Android devices have similar hardware characteristics. Most of them have standard 4,5-5,5 inches screens and 3 hard buttons. We give the best experience for seniors and for people seeking simple accessible solutions when using standard devices. The distribution of this product will benefit users, companies and the Android itself. With the adoption of this solution there are great benefits at stake as:

  1. Seniors will be able to use smartphones with convenience
  2. OEMs will diversify their terminal portofolio with products that matter
  3. Telcos will have accelerated ARPU as a migration from feature phones to smartphones means a migration from prepaid to postpaid customers
  4. The systemic effects of having accessible technology will grow the Android community with benefit the Android ecosystem itself

Especially OEMs will bring value and diversity to their terminal portofolio. Devices with the Katsuna OS can be a key differentiator and attract new customers. OEMs can distribute more devices increasing their volumes while there are no research & development inhouse costs. The Katsuna solutions are designed for a global audience and have multicultural fit.

We would like to work together with companies able to create and distribute mobile devices to reach happy out-of-the box customers.
