Ideas can strike at any time. Inspiration can come and go in an instant, and being slow on the draw can cost you a good opportunity.

When it comes to note-taking software, Evernote is the literal elephant in the room. Evernote is a comprehensive suite that turns photos, web pages, sound clips and even handwriting into notes. You can attach files, create annotations or comments, organize by folder and search through collections of notes. Best of all, Evernote automatically syncs your data across your devices so you can instantly retrieve your notes on your computer. Evernote is free for personal use with premium subscriptions for additional features.

2. OneNote

OneNote is Microsoft’s entry in the mobile note-taking market. As a Microsoft Office product, it has the prestige of being part of the world’s most popular office suite. OneNote separates collections of notes into sections, which are further broken down into pages. Pages can be sorted in a hierarchy, making it possible to form logical relationships between different pages. You can attach files to pages, insert images, and handwrite notes. Pages grow dynamically to be almost infinite in size, resulting in a smooth uninterrupted workflow. Since OneNote is part of Office 365, your notes are automatically saved to the cloud and can be accessed through any web browser. The OneNote app is free, but requires an active Microsoft account.

3. Google Keep

Google’s Keep is a great way to not only take notes, but also find information related to your notes. Keep integrates with other Google components to provide audio transcription, search for data related to a topic and even store location data to pull up notes when you need them. With newer Android phones, using Keep is as simple as saying “OK Google, take a note.” Keep automatically syncs to your Google account, making it easy for you to share your notes with others and to retrieve them later. Google Keep is free and works on almost all Android phones.

For those of us who are attached to hand-writing our notes, there’s Write. Write’s interface mimics a traditional college-ruled notebook, making it possible to jot down thoughts or ideas as if you were writing on a sheet of paper. Write supports pressure-sensitive styli, document attachments, comments, different “paper” types, copy/paste and split-screen viewing with a web browser. Write is freely available for Android and all major desktop operating systems.

Keeping your thoughts organized can seem like a daunting task. These apps can help you get on the road to becoming more centered, more organized and more productive.

How Do Free Mobile Apps Make Money?

How Do Free Mobile Apps Make Money

You love your smart phone and the unlimited access you have to free mobile apps, but have you every wondered how developers of mobile apps actually make money from your free download? Apps like Angry Birds report annual revenues in the hundreds of millions of dollars. How is this possible? Mobile app developers use several strategies to make money off your free downloads.

How to Plan Your Next Crowdfunding Campaign

Why the Freemium Model Is the Best Option for Newbie App Developers


As the modern adage goes, “if you didn’t pay for it, you are the product”. Mobile app developers are literally selling your eyeballs to the highest bidding advertisers. Downloads essentially amount to traffic, and traffic can be monetized through advertising. Most free apps use advertisements of some kind to make money off downloads.

Premium Versions

Apps often offer a free download of their app (often called the “lite” version) which offers some of the features - but not all of them. The only way to get the full app benefits is to upgrade to their premium version. This is a clever marketing tactic, though developers have to strike a good balance of features offered on each version. The challenge with this tactic is to make the free version appealing enough that people want to use it, but lacking enough that they eventually want to upgrade to the premium version.

In-App Purchases

This model is similar to the “lite vs. premium” model. The basic app is free to download, but if you want to use the app to its fullest extent, you will need to purchase additional features.

Free for a Limited Time

The immensely successful text messaging app WhatsApp offers free downloads, but only for the first year. After that, you have to pay $0.99 annually to renew app access. WhatsApp gives away one year free to convince you that you can’t live without their app. Then they make one dollar per year off you indefinitely. WhatsApp has hundreds of millions of users worldwide and produces enormous revenues through the app renewal fees.

Are Any Apps Truly Free?

There’s no such thing as a free lunch, so is there any such thing as a free app? Apps can be considered free because you can download and use them without paying any money. Nevertheless, you should be aware of how developers are planning to make money off your download.

Aside from a warning notification, your mobile device’s LED flash will glow red to indicate that a critical temperature has been reached. When that happens, close all apps immediately and allow your device to cool down in a well-ventilated area.

Metal Sniffer

When a call comes in, the app says the caller’s name over the ringtone. If the caller is not in your contacts list, the caller’s number is then read aloud.

Its reverse phone lookup functionality works for both landline and mobile phone numbers. Offering coverage worldwide, this app shows you the caller’s name and location whenever a call comes in.

So, it is highly likely that your unknown caller is readily recognizable through the app’s caller ID. The free app also comes with a built-in blocker to filter out unwanted numbers.
