No secret. A little puzzle app company I’ve been running for a while: www.eggheadgames.com. No ads or gamification. Just classic paper magazine puzzles. Pay for more or subscribe for unlimited play.
"Another vote for s7. We successfully embedded it and SQLite as the (non graphics) engine for otherwise native apps on iOS and Android. Super fast. Great FFI. Reliable. Small. Huge benefits from shared code across our mobile apps, insanely fast unit tests and a clean set of tooling.
Ultimately we switched to Fennel as a more pragmatic Lisp for mobile. AFAIK we were alone using s7 on mobile whereas Lua especially is a common mobile extension. Partly also this reflected the state of r7rs Scheme compatibility. We were running Guile on the desktop for development while shipping s7 and subtle incompatibilities would bite us regularly (a fun one was parameter evaluation order).
Thumbs up to both s7 and fennel for their great projects and community."
