Twitter encourages people to summarise their thoughts in 140 characters, but you are bound to end up in situations where you need more than one tweet to express yourself. In such cases, all you can do via Twitter's website and official apps is reply to your own tweets to create a chain of linked thoughts, something that's often called a 'tweetstorm'.
Not everyone is a fan of tweetstorms - they can be quite annoying as they fill up the entire timeline of people following you, who might not be interested in the particular topic you're mass-tweeting about. If you don't mind subjecting people to that from time to time though, then we've got a good app you can check out.
Storm It, by Chennai-based NFN Labs, which gets its name from the term tweetstorm, is an app that breaks your thoughts into tweets and adds a number to chain them together. Apps such as Tweetbot already let you link multiple tweets to one long conversation. Storm It has a different solution to the problem. Instead of typing multiple tweets, you type as much as you want and then hit the Tweet button. The app will automatically break down text to tweets, and add a number to indicate that this is a chain of tweets (1/10, 2/10, etc).
This is among the simplest apps we've used. It does just the one thing - convert a big message into a series of tweets. That allows the app to be minimalist and clean, which is a plus. As soon as you open the app, you can start typing. It's great that the typing area isn't hidden behind a menu, and you don't have to tap a button to start typing. A button on the top right shows you all of your tweetstorms, so you can quickly reference them. The gear icon on the top left shows you the settings menu. There's just one preference toggle here - switching from 1/n style to 1/ style. N is the total number of tweets in the sequence. If you want to let your followers know how many tweets are there in the chain, the 1/n style is good.
Before you hit the tweet button, you can tap the eye icon next to it to see how your thoughts will appear as tweets. This is a decent feature but we feel that the app should show you a preview before publishing on its own. This should ideally be a preference but if the developers have made this as a design decision, then we can't complain much. Tapping the eye icon is easy enough.
We did miss an autocomplete feature for mentions and hashtags. If you want to mention any accounts or add hashtags, you'll have to type them manually. This is quite cumbersome. We also missed the ability to separate tweets manually. The current format of Storm It automatically breaks down your long thoughts into tweets, but we felt we could do with a bit more control. This could help you avoid tweets breaking off mid-sentence. Otherwise, the app worked more or less as expected. It's targeted at a small niche and is totally free without ads.
There are a few other apps that we came across - pmarc and WriteRack - that allow you to quickly and easily send off a tweetstorm. These apps are all fairly similar as the basic concept is really simple, so there's not too much to choose from between them. If you tweet a lot and want an app that lets you chain your tweets, Storm It is a pretty good choice.
