Web application development
Customer portals, booking systems, dashboards and internal tools built with modern, well-documented technology that another developer can pick up years from now.
Read moreEnterApp designs, builds and maintains web platforms, mobile apps and internal tools for small and mid-sized American companies. We are a small senior team โ you talk directly to the people writing your code, and to the owner, Daniel Smith, whenever you want.
Most of our clients arrive with a spreadsheet that outgrew itself, an outdated website, or an idea that needs a first working version. We cover the whole path from the first sketch to the running product.

EnterApp was started in 2017 by Daniel Smith after a decade of building software inside larger agencies, where clients were often three layers away from the engineers. We kept the engineering standards and removed the layers.
No project starts without a written plan, and no invoice arrives without an agreed milestone behind it.
We listen to the problem, ask about your current tools, users and deadlines, and tell you honestly whether we are the right fit.
Within three to five business days you receive a document with deliverables, milestones, assumptions, exclusions and a fixed price or a capped range.
Wireframes and a clickable prototype come first, so changes cost minutes rather than development weeks.
Every sprint ends with a working build on a private staging link and a short recorded walkthrough.
Cross-browser and device testing, performance tuning, documentation, and a training session for your team.
Optional monthly care plan: monitoring, backups, security updates and a budget of improvement hours.
"We ran our rental business on three spreadsheets and a shared inbox. EnterApp replaced all of it in eleven weeks and stayed on for support. The weekly demo calls were the part I appreciated most โ nothing was ever a surprise."
"Daniel told us in the first call that half of what we asked for wasn't needed yet. That cut our budget by a third. Two years later we're on version four and still working with the same two engineers."
"Our old app crashed constantly and the previous developer disappeared. EnterApp audited the code, gave us a written report, and rebuilt the broken parts instead of pushing a full rewrite. Refreshingly honest."

Our studio sits at 1960 North Piedra Road, Sanger, California 93657, about twenty minutes east of Fresno. Clients in the Central Valley are welcome to visit by appointment; everyone else works with us the way modern teams do โ scheduled video calls, shared boards and a staging link that is always current.
We serve clients in all fifty states and keep our working hours on Pacific Time, 8:00 AM to 6:00 PM, Monday through Friday. Support-plan clients also have an emergency contact route for outages outside those hours.
Send us a short description of what you need. Daniel or a senior engineer will reply within one business day with honest feedback, a rough budget range and a realistic timeline โ no sales scripts.
