What we do
Five services, one accountable team
Most of our clients arrive with a spreadsheet that outgrew itself, an outdated website, or an idea that needs a first working version.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.
📱
Mobile app development
Native-quality iOS and Android applications, including App Store and Google Play submission, release management and post-launch monitoring.

UX & interface design
Research, wireframes and clickable prototypes so you can see and test the product before development budgets are committed.

API & systems integration
Connecting the tools you already pay for — accounting, CRM, payments, shipping, ERP — so that data stops being re-typed by hand.

Maintenance & support
Monthly care plans covering updates, security patches, backups, uptime monitoring and a named engineer who already knows your system.

Technical consulting
Second opinions, code audits and platform reviews for owners who need clarity before spending on a rebuild. Delivered as a written report.

Why owners hire us
A studio small enough to care, senior enough to deliver
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.
- Direct access. You have the owner's phone number and email from day one.
- Written scope. Every engagement starts with a document describing what will be delivered, when, and for how much.
- No lock-in. Source code, repositories, domains and hosting accounts are registered in your name.
- Weekly demos. You see working software every week, not status slides.
- Honest refusals. If an off-the-shelf product solves your problem for $40 a month, we will tell you so.

How we work
A predictable process, from first call to launch
No project starts without a written plan, and no invoice arrives without an agreed milestone behind it.
Discovery call (free, 45 minutes)
We listen to the problem, ask about your current tools, users and deadlines, and tell you honestly whether we are the right fit.
Written proposal & fixed scope
Within three to five business days you receive a document with deliverables, milestones, assumptions, exclusions and a fixed price or a capped range.
Design & prototype
Wireframes and a clickable prototype come first, so changes cost minutes rather than development weeks.
Development in two-week sprints
Every sprint ends with a working build on a private staging link and a short recorded walkthrough.
Testing, launch & handover
Cross-browser and device testing, performance tuning, documentation, and a training session for your team.
Support & iteration
Optional monthly care plan: monitoring, backups, security updates and a budget of improvement hours.
Client feedback
What working with EnterApp is like
★★★★★
"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 — 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."
Where we are
Based in Sanger, California — working across the United States
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 — 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.
