### 1/5 — App doesn’t work

*2021-03-02*

Don’t bother with this app. It just stays on loading screen forever

**Developer response:** Thank you for reporting. Version 3.1 fixed some issues, let us know if this solves the bug you experienced, or please report in which circumstances the bug is present, the iOS version, device type etc. You can submit such data on our website via the bug report form.

### 3/5 — Great concept, but needs work

*2020-10-05*

Sadly, poorly designed. Can’t save favorites and search terms are tedious. For example, can’t just search ALT- you have to spell it out. Great concept to have CTC-AE 4 and 5 in one app with performance scales, but please make it more user friendly! For an app that costs 2.99, should be bettter.

**Developer response:** Thank you for your request. The update 3.1 now includes two new views with two separate bookmark lists for CTC-4 and CTC-5. You can add the most common adverse events to these lists for quick access. Please feel free to visit our support website and ask for new features to be implemented in the next major release.

### 5/5 — Search doesn’t work for titles

*2019-06-04*

Edit 2019. Revising as promised due to developer response. 

Search “dyspnea”, nothing comes up.  “Breath” and dyspnea will show as a search result. Same with fever and most of the AEs I search for. 
Make titles of the AE terms somehow searchable and I will revise to 5 stars. Until then I’m looking for a different app.

**Developer response:** Finally CTC-AE has been completely rewritten and the new search feature scans all the fields: MedDRA, SOC, Term, Definition.

### 3/5 — Needs more

*2014-01-11*

The blood disorders section leaves out thrombocytopenia and leukopenia, for example.

### 4/5 — A good start

*2013-07-15*

It is useful to have this information at hand. A favourites list would be very helpful.

### 4/5 — Interesting app

*2012-01-08*

An interesting and easy to use app.  Perhaps adding in more adverse event definitions would be helpful, such as thrombocytopenia and leukopenia.

### 3/5 — Add search tab 4 iPad!

*2011-09-23*

Please add search capacity for iPad.

### 4/5 — great!

*2010-10-10*

so much better than carrying around the "not so little" notebook versions. 
any chance on getting ecog and karnofsky performance scals also?

### 5/5 — Excellent program

*2010-05-08*

As a clinical researcher, I find this program to be a great substitute for the usual spiral notebook!
