Independent app studio · Sheridan, Wyoming
EFN Group LLC — Software worth the home screen.
EFN Group designs, builds, and ships small, sharp consumer apps — a restock radar, a walk-to-unlock for your screen time, a peptide companion, and an atlas of the abandoned world.
The Index
Selected work, 01–04. Every app is designed, built, and operated in-house.
Stepsy
Walk more. Scroll less.
Turns steps into screen time. TikTok, Instagram, YouTube — locked behind your daily walk, powered by Apple Health and Apple's Screen Time controls.
Dosely
The all-in-one peptide tracker.
Log doses, manage vials, plan cycles, and get the exact units to draw every time — reminders, a reconstitution calculator, and a 17-peptide atlas that talk to each other.
uMaps
Map what the city left behind.
A field atlas for urban explorers — documented ruins, honest hazards, and access notes that lead with legal routes. Locations are earned through trust, never sold.
Ethos
How a four-app studio stays sharp.
01
Small, native, fast.
Tiny team, minimal dependencies, platform-first builds. Every app earns its megabytes — nothing ships that doesn't pull weight.
02
Honest by design.
Factual copy, no dark patterns, subscriptions that say exactly what they cost. If a feature isn't shipped, it isn't advertised.
03
Ship, then sharpen.
Real users beat perfect roadmaps. We launch lean, listen hard, and iterate until the product feels inevitable.
