Ratings and Reviews


Great app with configurable possibilities

This is a very simple app to log lots of data to help track your asthma. As well as logging medication and peak flow you can record symptoms, triggers, symptoms, etc. The best thing is that you can customise the app to record anything you want so if there's something missing that you'd like to track it's no problem.

The support from the developers is excellent too. I wanted to transfer the data from my phone to my wife's and they quickly responded to my question and provided a solution (turn off iCloud integration and you then get an option to export data via email).

I do wish it integrated with Health Kit but that's my only (minor) gripe.


Update has screwed everything and lost my data - just endlessly installs

This was the best I found, not bad to use but I made the mistake of getting the update. It just keeps installing, every time I try to open the app it goes back to the beginning and all the links for support, website etc just go to 404, website not up yet etc. And I can't go back to the old version.

Please if ANYONE from dangerdown is actually reading this, can you tell me how to get in touch for tech support asap? I really do need my data and will have to stop using the app if this doesn't get sorted - not impressed at all by this and by the lack of contact options.


Easy to use, configurable

Nice app, easy to use, very customisable
Easy to email the data and charts out
Graphics clear and good
Good value at the price

Few points
Setting fev1 via a slider is a bit tricky, would prefer a keypad
Would be nice to be able to compute fev1 predicted and %fev1 based on height and weight values
Would be nice to plot height and weight as graphs
Fev1 chart could do with auto scale on y axis, found it uses about 8L and all actuals squashed at bottom as using this for a child so i am focused in the sub 2 L area
Units of weight not very clear

Minor stuff
Would prefer use of the word settings to templates
Some of the edit screens in the templates, are a bit tricky to exit from but all works ok
