MenuHow difficult is it (in terms of programming) for a mobile app to track a user's mileage without displaying a map?
Would this use a large amount of mobile data?
Would having this running in the background use as much battery power as say Google maps (without ever having to display a map)?
Note:It's okay if the app is measuring in intervals (every 1/8 mile) if that would help reduce the data or battery useage...

Assuming you are looking for software, not in-car telematics, and you are willing to integrate rather than build it yourself, you could try using ZenDrive. That would give you a lot more than mileage too (eg, driving behavior).
This should neither use a large amount of mobile data nor use as much battery as Gmaps. Can't speak for iOS but this is what the Android documentation below has to say on location strategies and what it boils down to is that you need to determine how much accuracy your app needs, pick your strategy and maybe implement it as a background service that talks to your app. Someone who coded for Android before should have a prototype up and running within a few days. I assume however that this involves extensive testing on various devices and OS versions (the tricky part of mobile development).

Yep, you would be polling intervals/speed and saving those locally during a drive session then you would post those numbers back to the server for calculation. No need to show a map.

What is the best way to implement sharing in a native app and mobile website?
I've been developing web and iPhone apps for a while and I usually recommend to first use the provided sharing mechanisms. They provide great flexibility and as well don't require your app to request permissions on external networks. Using the iOS SDK sharing components will also save you precious development time. The most important part is the content that will be shared. On that side, make sure all the content has a unique URL, and can be properly consumed on all plateforms, desktop and mobile. Pay a particular attention to the head meta tags of those pages. Open graph and Twitter tags are not optional anymore and help driver a better visibility on the networks your content is being shared onto. Don't forget to track with an appropriate analytics tool how your users use the sharing module. Then you can evaluate the pertinence of building something custom.FV

How do you take an app idea and turn it into an app? Who will help make the app? How do you connect it through social media? How much does it cost?
Having gone through this multiple times either in new startups or for side projects, here is how I would approach turning your idea into an app. 1. Defining the Minimum Viable Product Your first goal with any new idea should be about proving the idea and finding a market that wants the app you want to build. Achieving that quickly is probably one of the most important thing. To achieve that, you will need to write the specifications that will constitute your MVP. The MVP is basically the simplest expression of your idea to prove it. This step should not cost you much as you can do this on your own. 2. Design the app Before starting any development work, I would suggest you work with a good UX/UI designer to create wireframes and mockups of the app based on the specifications you came up with in step 1. You can find good designers in meetups & hackathons or on website like Dribbble or 99designs. If you want to reduce your costs, you can give shares in the project to the designer. Otherwise, it really depend on the size of the MVP but I would say it will probably cost between $5K-$10K. 3. Develop the app Once you have the specifications and the design of the app, you now need to find a good developer that will build it. Again, you can find good developers in meetups & hackathons or on sites like Github. If you want to reduce your costs, you can give shares in the project to the developer. Otherwise, it really depend on the size of the MVP but I would say it will probably cost between $10K-$25K. For this part however, I would recommend the developer becomes part of the project as his engagement will most likely be higher. 4. Test the app This step is not only about making sure the app is bug free, it's also making sure the app does what was intended in the specifications. To test the app, you can use platforms like BrowserStack or SauceLabs which gives you access to multiple devices/browsers. You can do this step on your own so the cost will be for the subscription to the test platform which would be around $100/month. Hope this helps and good luck with your project.VL

What is the best way to do a permissions system for a low traffic administration system, PHP preferred, but general suggestion is also valuable.
Hi, I have been a PHP developer for 13 years and have experience building enterprise applications. What framework are you using? Most PHP frameworks have a built in authentication and authorization mechanism. For example, Yii has a builtin RBAC system that allow you to define a hierarchical permission system. If you're not using a framework or you just want to implement your own system for whatever reason then you can utilize Object Oriented Design and implement a Base controller (if MVC) that checks the permission for each request. That won't use a lot of if statements. Probably need more info, to give definitive guidance. Hope that helps.AP

Programming language for web platform?
NOT Wordpress! Facebook uses PHP among other languages, if that tells you anything. Every programmer will be bias toward what they like and what they are used to coding with. The bigger question for you is, have you completed your due diligence? Is there a real need for another crowd funding platform? Why would yours be so different that it would stand out among the others? Who is you target market? What is your unique selling proposition? How big is your potential market? Should you go vertical or horizontal? You may have already answered these and the two dozen other questions every entrepreneur must ask before they waste valuable time and money to become another business start up statistic. Assuming you have a strong grasp of where you are heading and a solid strategic blueprint to be able to predict your growth, the last thing I will leave you with is this. The programing language is not nearly as important as your database structure and IT infrastructure for the purpose of scale. Not to say the language is not important - all three components work together. Spend time on the other two and work backwards. If you would like to discuss this further at no charge, use the link below. I provide a free 30 minute consultation to first time callers. https://clarity.fm/kevinmccarthy/FreeConsult Best regards, Kevin McCarthy www.kevinmccarthy.comKM

If I'm looking to create a mobile app for my startup, should I first hire a designer or a developer?
Designer. Specifically a UX "designer" as you say, who doesn't just draw screens, and won't draw any for weeks or months. They will not just use their knowledge but will go out and talk to users, observe how they solve the same problem today, and help create the scope of work, and design the basic functionality. If you hire a developer first, they will build stuff that may or may not be of any value. If the company survives the first few rounds of building the wrong thing, you are still spending a hell of a lot in rebuilding, re-marketing, etc. etc.SH
