Depends what you are looking to have developed. Are you looking to have a game or a business app developed. I live in Dundee. I would ask any of the gaming companies here to make a business app. There are however a shed load of companies here who make businesses apps (including me) who are more than capable of handling any size and type of business app.
I would give you two pieces of advice, don't go for the cheapest option and buy on reputation.
If you're trying to cut corners at the very start of your project that does not bode well for the long term. The world of mobile phone apps is no different to any other business, you get what you pay for.
Here are the reflections to trust in mind prior to hiring services from mobile app development companies. • Choose the Mobile App Development Companies Based on Customers' Reviews and Feedback • Security of the App Idea • Effective Delivery Management • App Designing Standards
