Localization is key to local app adoption and revenue growth. A new guest post from Dimitris Glezos, founder and CEO of Transifex, explores the various translation solutions and workflows available today. Then he introduces the concept of Continuous Localization, a modern way of doing localization.

Using a Backend-as-a-Service (BaaS) can reduce development cost and time-to-market. It’s a simple way of getting a highly scalable backend solution without significant upfront investment. In a world where an app that hits the store top charts might gain more than a million new users before you complete your next iteration of development this is worthy of serious consideration.

Testing any mobile app presents a wide range of challenges. The often repeated but rarely followed software best practice of test early, test often is harder to adhere to than usual due to the fragmentation of the target environment and the relative maturity of tools. The increased acceptance of apps by mainstream consumers and intense competition have raised the bars for user experience and quality. There is more to test than ever, yet often very limited budget for doing so. Fortunately every challenge presents an opportunity and a vast array of tools vendors are racing to fill the gaps.

Usage Analytics tools help developers understand their users and the way they interact with their apps. Measuring app usage in this way and using the data to help target improvements to the app can significantly improve revenues. We asked developers to rate their primary analytics tool across a range of criteria. The results tell us which are developers’ first choice tools and how they compare.

Alexis Piperides, co-founder and CEO of Proto.io, takes us on a tour across the fascinating landscape of prototyping tools. In these early days of iterative design of mobile applications, can tools and services help to drive perfection?

There’s been much talk about App Store Optimizations (ASO) and tools are emerging to get that extra attention in app store search rankings. The good folks at XYO have been studying app search behavior since 2010. Recently, they talked to all the major ASO companies and got their feedback for their presentation on the topic. In this guest post, they’re happy to share the comments of ASO players and their own insights on the state of ASO.

The world is getting ‘App’ified – and India is entering the fray at full force! With India rapidly growing as a major app destination, it is important to understand the underlying drivers of this rapidly growing ecosystem. Is there an “apportunity” for your app in India?

The “write once, run anywhere” concept may be pure fantasy for most apps but sharing code across platforms is desirable and in some cases essential to making projects economically viable. With the application frameworks for all the biggest platforms being in different languages, the market for Cross-Platform Tools (CPTs) to enable code reuse is understandably the largest one (in terms of number of competing solutions) we track. The time required to evaluate all of them is far beyond what most developers can afford to spend on such research. So, which tools are the best?

As mobile apps become more sophisticated and expand their user base, the requirement for remote storage and user management becomes more important in terms of both functionality and scalability. Off-the-shelf mobile Backend-as-a-Service can save a considerable amount of time for developers that require backend support for their apps. Our Developer Economics 2013 report puts Parse firmly in the lead of BaaS services. But which selection criteria and features do developers really value?

Advertising is the most popular revenue model, while ads can also act as a promotion channel that facilitates app discovery. With 100+ ad networks and exchanges, there is intense competition, regional specialisation and niche solutions, but out of the fray, one service emerges as a leader: AdMob.
