Mobile, multilingual, and manga: how Africa's youngest readers are reshaping what a platform must be

Post 13 of 17 · The Somastars Phygital Thesis · Africa & Kenya

There is a version of a literacy platform that was designed in 2010 for a child with a school laptop, a stable WiFi connection, and 45 minutes of supervised screen time per day. That version of the platform is irrelevant to most children in Nairobi, Mombasa, Kisumu or Nakuru in 2026. The child who uses SomaStars is more likely to have a Tecno Spark or a Samsung A-series phone, a Safaricom data bundle that costs KSh 20 and expires overnight, and seven minutes between arriving home from school and the start of the evening meal.

A platform that does not account for these constraints is not a literacy platform for East Africa. It is a literacy platform for East Africa in a brochure.

The visual-to-text design standard

SomaStars' engineering team works to a visual-to-text ratio specification that is directly tied to the 15-level taxonomy. Levels 1 and 2 (board books, ages 5 to 6): 90 percent visual, 10 percent text. High-contrast art with clear panel boundaries that the computer vision system can segment reliably on a low-resolution phone camera. Levels 6 to 8 (early readers): 50 percent visual, 50 percent text, with half-page and spot illustrations. Levels 12 to 15 (middle grade and YA novels): less than five percent visual, and the CV system is used only to identify the book cover, not to extract panel-level content.

These ratios are not aesthetic choices. They are cognitive and engineering constraints simultaneously. A board book with 80 percent visual content and 20 percent text — rather than 90/10 — increases the decoding load for a Level 2 child and reduces the CV system's ability to cleanly segment the image. The ratio is determined by what the child's brain needs and what the phone camera can handle at the same time.

The typography constraint

For Levels 3 to 5 (early readers aged 6 to 7), SomaStars specifies Sassoon Primary typeface at 20 to 24 points. Sassoon Primary was designed specifically for beginning readers, with open counters that distinguish letters that children commonly confuse (b, d, p, q). Reducing the point size below 20 on a phone screen — for a child at this level — increases decoding time and error rates.

For readers with dyslexia, the OpenDyslexic font is available as a toggle from Level 1 onwards. This is not an accessibility afterthought. Given that Kenya's dyslexia diagnosis rate is almost certainly lower than its actual prevalence, many 'slow readers' in Kenyan primary schools are undiagnosed — the toggle is designed to be on by default until a child demonstrates reliable decoding speed at their level.

"A platform that ignores the Tecno Spark and the 20-shilling data bundle is a platform for East Africa in a brochure."

The manga question

Manga — Japanese comics read right to left, with a visual vocabulary distinct from Western comics — is now among the highest-circulating material in Nairobi's school libraries. Titles like Attack on Titan, Demon Slayer and My Hero Academia are read by Kenyan teenagers who have never been to Japan and may never have read a Western novel. SomaStars maps these titles to Levels 11 through 15, where the narrative complexity, vocabulary density and thematic depth justify the placement. The panel-reading direction is a brief orientation task. The cognitive demands of the texts are real.

The takeaway

The platform that reaches African children is the one built for the phone they actually own, the data they can actually afford and the books they actually want to read. Engineering for the ideal user is engineering for nobody. SomaStars was built for Grace in Eldoret, Kamau in Kasarani, and every child between them.
