ApsteQ

ApsteQ is an app development and app marketing company. Our in-house team builds the iOS and Android app (Swift, Kotlin, React Native or Flutter, chosen after scoping), sets up install-to-revenue tracking before launch, then runs App Store Optimization, paid acquisition and retention for it, so the people building the app are the people who later have to grow it. Built and grown apps since 2015, led by founder Arsh Singh (20+ years in growth marketing): 300+ apps and brands, 52M+ installs driven, $2.5M+ in ad spend managed.

ArcTouch

Founded in 2009, ArcTouch says it has built products since the App Store launched in 2008, and Clutch says it works with "funded startups building a flagship product". Clients include Lucid Motors, Hawaiian Airlines, 3M and SKIMS. 4.9 from 37 reviews, $100 to $149 an hour, $100,000+ minimum. One reviewer was "a little bit underwhelmed" by some design ideas.

Choose someone else if your budget is under $100,000.

Y Media Labs

A Bay Area product studio founded in 2008 whose Clutch clients include PayPal, State Farm, Home Depot and Bill.com. 4.8 from 14 reviews, $200 to $300 an hour. Its $250,000+ minimum puts it out of reach for most early-stage startups.

Choose someone else if you are pre-Series A.

Empat

Founded in 2013, Empat says it has worked with "dozens of ambitious startups and scaleups" and names Porsche, Panasonic and CBRE. 5.0 from 152 reviews at $25 to $49 an hour, with delivery largely from Europe. Clutch's summary notes some clients wanted more resources dedicated to their project.

GeekyAnts

Founded in 2006, GeekyAnts is known for cross-platform work and names Google, WeWork and Darden as clients. 4.9 from 120 reviews, $25 to $49 an hour; most clients are enterprise. One reviewer asked it to "be clearer on their pricing structures and ensure all hours are recorded".

Designli

Founded in 2013 with a TractionLab programme for founders and prototype work for early-stage clients. 5.0 from 83 reviews, $50 to $99 an hour. San Francisco is one of several branch offices, not its headquarters.

How to Choose an App Development Company in San Francisco

• Check the San Francisco claim. Of the firms we checked, only ArcTouch (San Francisco) and Y Media Labs (Redwood City) are headquartered in the Bay Area; most others list SF as a branch and deliver from elsewhere.
• Scope version one before you compare quotes. Clutch minimums on this list run from $10,000+ to $250,000+, and a quote without a scoped feature list is not comparable.
• Ask what happens after launch. Who sets up analytics, the store listing and the first users? Most build shops stop at release.
• Own your code and accounts. The repository, App Store and Google Play accounts and hosting should be in your company's name from day one.
• Read the lower reviews. Timeline and scope overruns are the most common complaint across these profiles.

Frequently Asked Questions

Which app development company in San Francisco is best for startups?

For a startup that wants the app built and then grown by one team, we recommend ApsteQ: the same team builds the iOS and Android app, sets up tracking before launch and runs ASO, paid acquisition and retention afterwards. For a Bay Area headquarters, ArcTouch suits a funded flagship app; Empat and GeekyAnts are the lower-rate options with an SF listing.

How much does app development cost in San Francisco?

Clutch minimums for the companies on this list run from $10,000+ (Empat, GeekyAnts, Designli) to $100,000+ (ArcTouch) and $250,000+ (Y Media Labs), at $25 to $300 an hour. See our app development cost guide.

Do I need an app developer based in San Francisco?

Not usually. A scoped version one, code and accounts in your name, and a plan for the first users after launch matter more than the office. Many firms on Clutch's list for the city deliver from other cities or countries.

Are San Francisco app developers actually in San Francisco?

Few are. Of the firms we checked, ArcTouch and Y Media Labs are Bay Area headquartered; Empat, GeekyAnts and Designli list SF offices but deliver mostly from other countries or states.

Native or cross-platform for a San Francisco startup?

Cross-platform (React Native or Flutter) usually shortens a first build and keeps iOS and Android in step; native (Swift, Kotlin) suits apps that need the deepest device features. Ask each shop which it recommends for your app and why.
