Software built for pure utility. Zero bloat, zero barriers.
simplebuildapps designs and ships fast, single-purpose Android utilities for students, educators, and everyday operators who need tools that just work.
"I build the apps I couldn't find."
Aryan • Solo Developer & Creator of simplebuildapps
I started simplebuildapps out of pure frustration. As a college student, all I needed was an attendance tracker that told me how many classes I could miss while staying above 75%. Instead, every app on the Play Store demanded mandatory email signups, loaded 10 tracking SDKs, and locked basic timetable math behind $8/month subscriptions.
So I built RollBook alone, without venture funding or monthly active user quotas. When an app is built by a solo developer who actually uses it, there is no investor incentive to degrade the user experience with deceptive paywalls or data harvesting.

"Finally an attendance app that doesn't ask for my phone number or spam notifications during lectures. The safe-bunk calculation saved my semester exam eligibility."
