Our thanks to Tapstream for sponsoring MacStories this week. Tapstream helps app developers earn more from their apps.

For those of you who don’t advertise your app, Tapstream is completely free. You can embed it in your website to understand which referring sites and which landing pages are responsible for the biggest share of installs. Alternatively, use Tapstream’s URL shortener to get this same data from social networks, email or anywhere else on the web. If you decide to spend money on mobile ads, Tapstream is partnered with the best ad networks out there to help you advertise and make sure you’re not double-charged for your users.

Beyond just telling you how your users are getting to your app, Tapstream keeps track of exactly how valuable each channel is. Automatic In-App-Purchase reporting tells you where you get the most of your revenue from. Add to that a bevy of features like device-aware shortlinks (that discriminate between iPhone, iPad and Android visitors to send them to the correct destination), cohort tracking and integrations with HootSuite, KISSmetrics and MixPanel.

Tapstream is already on your iPhone in many of the apps you use today - it should be in your app too.

Our thanks to MacPaw for sponsoring MacStories this week with CleanMyMac 2. CleanMyMac is the simplest, fastest way to clean your Mac and remove unnecessary junk that your computer doesn’t need or has accumulated over time.

CleanMyMac can scan your Mac and find – besides unnecessary system files – files that you haven’t opened in a long time and that you likely don’t need anymore. CleanMyMac’s algorithms will find cache files, system and user logs, broken login items and preferences, old iOS software updates, hidden iPhoto files, and other large files that only waste space on your Mac; with an intuitive interface, the app will allow you to safely remove them and regain space without causing any issue with OS X (the app is ready for Mavericks).

In order to ensure that CleanMyMac would always remove the right files from OS X, MacPaw built a Safety Database for the app – a set of rules and exceptions that CleanMyMac uses to properly clean up junk files without doing any harm to the user’s system. The developers published a blog post on this feature, which you can read here.

CleanMyMac 2 is available at $39.95. A free trial is available at MacPaw’s website.

My thanks to Backblaze for sponsoring MacStories this week. You need a backup of all the data on your computer, and Backblaze offers unlimited and unthrottled backup at just $5 /month per computer. Backblaze automatically backs up all your files – not just a subset of them – every day, all the time, so you won’t lose any of your data in case of theft, fire, flood, stolen or broken computer.

Backblaze was created by former Apple engineers, and the company understands the needs of Apple users. Backblaze has a native Mac app for Mavericks and it comes with an iOS app to remotely access, view, and share your files. Secure and offsite, Backblaze’s continuous backup ensures you can always view and restore files; once installed, you don’t have to think about complicated options and configurations – if it’s installed, Backblaze will do the rest for you.

Among other features, Backblaze supports external drives, uses military-grade encryption for your files, and it has a free web restore feature that also has file versioning built-in. Backblaze is online backup made easy, and you can check it out and sign up for a plan here.

My thanks to Flexibits for sponsoring MacStories this week with Fantastical. Both on the Mac and iPhone, Fantastical lets you create and manage events using a beautiful and intuitive interface with an expressive and accurate natural language parser. With Fantastical, you can type something like “Lunch with Michael at 1 PM tomorrow” and the app will create a calendar event for it, filling all the necessary date and time fields for you. Same for reminders, recurring events, and other commands. It’s great.

I’ve been using Fantastical for years now, and I wouldn’t be able to go back to using Apple’s default apps for events and reminders. Fantastical 2, which is my iPhone app of the year, introduced an iOS 7 redesign and new features such as direct Reminders integration, a new week view, a dark theme, and more. For power users, Fantastical 2 has a powerful scheme that lets you chain it to other apps to build handy automated workflows.

For a limited time only, Fantastical 2 for iPhone is $1.99 (60% off) and Fantastical for Mac is $9.99 (50% off). You can find out more about Fantastical 2 for iPhone and Fantastical for Mac here and here.

Our thanks to Ohai for sponsoring MacStories this week.

Ohai is a journal app for keeping track of memories. Save thoughts, photos, and locations into a beautiful digital book, and flip back in time day by day. Check in to places, either privately, or to Foursquare, Twitter, and App.net. Your journal entries and photos are stored securely on App.net, even free accounts, so your data is always portable and recoverable. It’s the perfect way to capture memories for the holidays.

With the recently released 1.1 update, Ohai added a new design for iOS 7, Foursquare check-ins, and the ability to edit and delete journal posts. You can now create posts for events in the past, and you can also add new thoughts and photos without locations.

Ohai is currently on sale at $2.99 on the App Store (regular price $4.99).

MindNode makes mind mapping easy. Mind maps are a visual representation of your ideas, starting with a central thought and growing from there. This allows you to brainstorm and organize your thoughts in an intuitive way, so you can focus on the idea behind it.

MindNode 3 for iOS was just released and it comes with a completely new user interface designed for iOS 7. New features like MyMindNode - a service that allows you to embed your MindMaps on any website - and iCloud folder integration mean sharing your documents between all your devices has never been easier.

I’ve been using MindNode for years and I’m a fan of version 3.0 (my review). What I like about MindNode is that Smart Layout makes it easy to build large maps without having to worry about rearranging nodes, and the beautiful new default theme on iOS 7 looks great on the iPhone and iPad. In the new version, MindNode also supports keyboard shortcuts on the iPad: this allows me to create a map in a few minutes like on my Mac while retaining the iOS app’s handy Inspector menu. I rely on MindNode to organize topics for my longer articles and reviews, and I highly recommend it.

MindNode 3 for iOS is available on the App Store.

Our thanks to Smile for sponsoring MacStories this week with PDFpen.

PDFpen is the premiere Mac app for editing PDFs to add signatures, text, and images, as well as make changes to correct typos. PDFpen can perform OCR (Optical Character Recognition) so that pictures of text in your document will be turned into real text that you can use. With support for cloud services, PDFpen can keep your documents available across OS X and iOS thanks to PDFpen for iPhone and iPad.

With version 6.1 of PDFpen, Smile added support for PDF stamps: you can now browse a library of standard business stamps (e.g. Approved, Confidential, Sign Here) to quickly apply to your documents without complex editing required. In this version, Evernote users can also save PDFs directly to Evernote Business notebooks.

PDFpenPro –  the advanced version of PDFpen – received some cool new features as well. The new version adds support for automatically detecting and creating form fields for an entire document (in addition to per page) and there’s a new “Create Links from URLs” command to detect and create links in a document.

PDFpen is available on the Smile Store and the Mac App Store. A free demo can be downloaded on the Smile site.

Our thanks to Doxie for sponsoring MacStories this week.

Doxie Go is the tiny, rechargeable mobile paper scanner that scans anywhere with no computer required. Scan paper, receipts, and cards, then sync to Doxie’s elegant Mac software.

Doxie makes it easy to go paperless, create searchable PDFs with integrated ABBYY FineReader OCR, and send scans to your favorite Mac and cloud apps – Dropbox, Evernote, and more.

It’s time to finally go paperless. Get your new Doxie Go direct from Doxie, from Amazon.com in the USA, or from Amazon.co.uk in Europe.

Federico’s note: I have two Doxie scanners at home and my family and I have been using them for almost two years to scan important work/health-related documents and old photographs. I like the Doxie scanners because they produce higher-quality scans than what you’d normally get with an iPhone’s camera, but they’re portable and they don’t require much desk space.
