What’s New

Version 1.8.1

This version adds support for new devices.

Important note for users who used a linked Dropbox account: This version updates to the new version of the Dropbox API, and requires that you re-link your account from the settings screen.

Changes in Version 1.8:
- Resolves a crash on load that effected a small number of users. Sorry about that!
- This version should better preserve data in the case of an application crash.
- Removes support for daily step tracking. This feature is better implemented in the native Apple Health app (and other third party applications), and has consistently been a source of bugs.

Changes in Version 1.8.1
- Improved icon locations on the iPhone X.
- Changed the "Vampire" theme to use a true black color, for a great look on the iPhone X.

Really good app

Update: it’s working fine now, and it does a great job of calculating totals, averages, and producing a graph of results by date.
I’m now very satisfied and glad to have it.

Some months ago:
Hey developer: you got something good here. Fix it and I'll write a proper review.

Developer Response ,

Sorry for the crashes. A new version coming in the next few days should solve a few of the most common crashes. If you are still experiencing issues, please email me with details about when the crashes are happening and I will do what I can to resolve them. Thanks for the feedback, and sorry again for the inconvenience.

Handy app and helpful developer

I think that this will be a very helpful data tracking tool on iOS. I like the layout and feel of the app. After asking about URL schemes via Twitter, I found that the developer was very responsive and open to suggestions to help make Quantifier a more robust app.

Quantifying at its finest

Quantifier offers tracking databases, for number fanatics. It never crashes, and the developer support is top notch.
