It would also be great to have a space to add other species recorded at specific sites like RsPB bird count offers. It would probably provide a fuller picture overall especially in SSSIs etc. Just something that would make it better for me. ### 1/5 — Annoying *2026-03-01, version 8.5.3* It isn’t letting me to count the butterflies ### 5/5 — Great butterfly id app *2025-08-12, version 8.5.2* I used this app for the last 3 Big Butterfly Counts, one improvement I would like to see is the ability to save a profile including location, number of counters, as filling it out each time is tedious. Otherwise great app. ### 5/5 — Working again 2025! *2025-07-26* After not working at the start of the count (on my phone anyway!), when the version said it should work, I deleted and then downloaded the version available from just a few days ago! Now off to count those butterflies. Yay! Thanks to those who fixed things, really good! ### 5/5 — Broken 16 July 2025 *2025-07-25* App freezes on launch. iOS 15.8.4 Removing and reinstalling makes no difference. This is very disappointing as I make many recorded counts over the years. Edit: app update version 8.5.2 posted on the 23rd of July has fixed the app and it is now working on iOS 15.8.4 ### 5/5 — Fritillary *2025-07-24, version 8.5.2* I can’t add silver washed fritillary ### 1/5 — Fix the bug! *2025-07-20, version 8.5.1* App freezes on opening. Deleting and re downloading has made no difference. iOS 15.8.4 and according to the description, it should work on iOS 14. Disappointing as I was going to take part for the first time ### 1/5 — App not working *2025-07-18, version 8.5.1* App feeezes on iPad and iPhone OS15.8.4 despite saying it should work for OS14 and above. Disappointed. ### 1/5 — 2025, not working! *2025-07-18, version 8.5.1* I have taken part in the Count for a lot of years, but this year the app wont work, only get a full screen banner saying Butterfly Count. Have deleted, re - downloaded, checked and it says ‘works on this phone’. No controls visible, or tabs to open. A pity, was looking forward to the count as there seem to be a lot of butterflies this year. Just thought I’d write, as I see just one other person saying its not working this year. ### 4/5 — Different species *2025-07-18, version 8.5.1* What do I do if I observe a species not on your id list. I saw a butterfly with similar colouring but very different wing shape. ## Frequently asked questions about Big Butterfly Count ### What is the Big Butterfly Count app?
