Really solid work. Picked up this mobile template for a client app — Components are cleanly separated and easy to extend. Docking half a star only because I wanted a couple more examples.
Clean and well thought out. Used "Service Booking App Template" to build my app and it cut days off the build. Will definitely check their other products.

Punches well above its price. As someone who builds these all day, components are cleanly separated and easy to extend.
Great starting point. TypeScript types are actually accurate, no fighting the compiler, and examples matched the actual API, which is rare.
Rock solid so far. As someone who builds these all day, the abstractions are sensible and easy to swap out.
Clean and well thought out. Dropped this mobile template straight into the app; even the tricky env setup was explained well.
Genuinely impressed. Picked up this mobile template for a client app — Components are cleanly separated and easy to extend. No regrets.
Exactly what I needed. TypeScript types are actually accurate, no fighting the compiler, and the README covered every config I needed. Five stars, would recommend to my team.
Dropped it into my stack and it just worked. Picked up "Service Booking App Template" for a client app — Zero mystery dependencies, everything is documented.
