Frequently Asked Questions
What does App369 build for West Palm Beach businesses?

Do you provide ongoing support?
Yes. After launch App369 offers maintenance that covers bug fixes, iOS and Android OS updates, security patches, dependency upgrades and small feature work, so your West Palm Beach app keeps working as the platforms change.
