And it doesn’t stay in date as it jumps back a year or a month ### 3/5 — Left right reversal *2019-06-10, version 2.0* I love this app, but the headache location map is reversed. If you click on the “right” slide of the map, it records as left. ### 4/5 — Really useful app *2021-05-27, version 3.0* This is a really useful app. I previously just noted the same information down but this is logged in a much better way, and makes it easier to look at all the data in a structured way. It would be great if the app database could be backed up to iCloud so that when switching to a new phone or using a different phone the data could be retained and synchronised in the app. Thanks. ### 4/5 — Works for tracking CH Attacks *2018-12-18* Works very well for tracking cluster headache attacks. Easy enough to use. A few suggestions: make a quick start button right on the home screen. So I can open the app and hit “start” on an attack. That one less step would be hugely helpful during attacks. Allow the option to search a range on the graph. It only shows one year and one month. It would be great to look at 3 months or even search by attack severity or symptoms. Thanks for the app it has been very helpful! ### 5/5 — Thanks *2025-06-24, version 4.2.6* So much easier to document my CH’s , very good app for sufferers ### 5/5 — Clusters *2023-12-19, version 4.1.13* Really useful app. The best feature is the start finish button... because it is an accurate indication of time spent in pain. Only issue I have with it is that the meds part, usually deletes the wrong item. I have told neurologist about the app, so that he can recommend to others. ### 5/5 — Great app! *2021-09-25, version 4.1.1* Great to record headaches. In the throes of a cluster headache there is not much I can do so to be able to just press a button to start it is great. Keeps running until u stop it. U can export the log in pdf format or spreadsheet to print to take to your doctor. Has a head diagram where u can note where headache occurred and has many options to record symptoms/meds etc. 10/10 recommend. ### 5/5 — Awesome! And very good *2021-09-21, version 3.0* After 30 years of hit and miss on a paper calendar, more misses, this chronic CH fellow really appreciates this app. If I could humbly suggest one item, allow a copy or repeat, it would be easier on this one per hour or every other hour nights. Normally I just don’t grab the phone but enter the next day. Again, great app! ### 5/5 — Tracking the beast *2021-01-21, version 2.2* I was so glad to find this app today! It works, quick, easy & no math! I input my headaches for the last week in less than 20 min & used it last night/this morning to keep track. Easy 1 button design made timing easy. Usually I go to the kitchen (harder for family members to hear me) & use the timer on my oven. This involves subtraction & often I leave a cryptic math problem on my notes pad. *I’d like to ask you to add a button for tracking “shadows” (predome/prodome) before/after the headache. Thanks for this app! ### 5/5 — Perfect way to log attacks *2020-09-13, version 2.2* I got this app to prepare for an appointment with a specialist and it is so nice to have such a good list of symptoms and everything else to choose from, plus the ability to add custom. The dark interface is a godsend when having a nighttime attack. ## Most praised reviews (3 highest-rated) ### 5/5 — Useful app *2020-09-11, version 2.2* This is a great app for tracking clusters 🤕 ### 5/5 — Great app *2018-08-23, version 1.0* I love using this app. However I recently switched from iPhone to android and I do not see an app for Android? ### 5/5 — Good app *2018-06-24, version 1.0* The app does exactly what it’s designed to do. Sometimes the attack comes on so quickly to start the app is next to impossible. Yet having the ability to adjust the times of start and end fixes that. Used this app regularly and I’ve learned some patterns and triggers. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
