About this Gig
Vetted Pro
Hey,
We've been fixing mobile apps for the last 12 years. My team worked with good, bad, and ugly applications, and our expertise allows us to make each app do what it should do - make money for your business and provide value for your clients.
This Gig is for you if you:
- Have a mobile app live in a store, and would like to add a few tweaks here and there
- Tired of looking for a developer each time you need an update for your app
- Had 15 new bugs after 5 were fixed in the last release
- Are not 100% sure how well your app is coded
How work is done:
- You send us a list of tasks/ requirements.
- After a code check, we give an approximate estimate for each task/requirement.
- After your approval, we track the time internally and send you reports upon completion of each task.
- You become another happy buyer!
This gig is mostly for custom offers, as each case is special.
Cheers,
Stan
