Adobe Acrobat Reader
On your iPhone you'll already be able to view and synchronise PDFs via Safari and Apple Books, but Adobe Acrobat Reader adds that that extra bit of functionality. Most importantly, it allows you to edit and annotate PDF Files.
Any.do is a free productivity app for iPhone that delivers in just about every way. It's great to look at, easy to use, and effective at helping users get stuff done.
In either the category or schedule view, the task list is presented in a clean, spare format, and Any.Do has many layers of organisation. It's both easier to use and more pleasing to look at than the native Reminders app in iOS.

Documents is, as the name suggests, an app for keeping your documents in one convenient place, particularly when on the move. Those documents include text, audio, music files and web and email content. It's been awarded 'Editors' Choice' by Apple in more than 70 countries, which is a fair reflection of the app's quality and usefulness.
Dropbox's cloud service lets you store and sync files online, so they're accessible from multiple computers. And with the company's free iPhone app, you can access your Dropbox files on the go.
It's a reliable and user-friendly offering. But Dropbox has an ace up its sleeve in the form of Photo Uploads. Install the Dropbox iOS app and switch this on and any pictures snapped in your iPhone will be copied to your Dropbox cloud storage, making it easy to quickly view the files and share them with other people.

This note and snippet managing service lets you type text notes and take photo notes with your iPhone's camera. After you capture a note, Evernote automatically uploads everything that you put into it to the company's servers, where your notes are indexed for easy search and retrieval, and become available for syncing to all your devices. Fast, smooth and extremely functional.

Excel is used all over the world to view and edit spreadsheets, it's available on your iPhone too - a worthy recommendation. However, you'll only be able to view spreadsheets via the app, as if you want to edit or create them you'll need an Office 365 subscription.
PowerPoint is used all over the world to view and edit presentations, and is available on your iPhone too. However, you'll only be able to view presentations via the app, as if you want to edit or create them you'll need an Office 365 subscription.
Word for iPhone is a worthy recommendation. However, as with the other Office products on iPhone, you'll only be able to view documents via the app, as if you want to edit or create them you'll need an Office 365 subscription.
If you're looking for a word-processing app that doesn't require a pricy subscription, Google Docs is a solid free option. It provides many of the same features as Microsoft's offering, and is linked to your Google account so you can create, edit and access your documents from anywhere - not just your iPhone. You can even export files as Microsoft Word-friendly documents, so there's no real reason not to give it a go.
There's also Google Sheets, a strong free alternative to Microsoft Excel for iPhone.

MultiTimer might be a bit of a niche app, but it provides a great service for those that require it. Say, for example, you want to cut down smoking and want to increase the time between cigarettes. You could use the iPhone's built-in Timer function, but it requires you to manually restart it every time it ends.
The easier option is to download MultiTimer, an app that provides the ability to set multiple recurring timers - great for quitting smoking, managing cook times and more. The Today Widget and Apple Watch companion app allow you to check in at-a-glance too.

Everyone's using Slack by now, aren't they? Well, possibly not. But there are certainly a lot of workplace teams out there who could benefit from it.
Slack is a simple private messaging system, organised by team (your colleagues) and then subdivided by channel (specific areas of interest). Anyone who is a member of a channel can post and read messages on it, and invite other members of the team to join.
You can leave channels, you can mute them, you can dip in and out; it's a clever and highly customisable way of organising the way various parts of your team can let each other know what needs doing - and post web links, images and documents too, where applicable.
The iPhone app, which is also free, makes it easy to stay in touch, but not overwhelmed, when you're out of the office. Although judicious use of the app-specific do not disturb feature is recommended.

Having the ability to convert money on the fly, using the latest exchange rate (provided you've connected to the internet at some point) is extremely handy. The app is useful especially when you're abroad and want to know the conversion rate or even how much the currency exchange booth is ripping you off by.
