### 5/5 — Great free app

*2025-02-04, version 4.4*

Does exactly what it says: provides details of the MARILYNS of Wales. I’ve seen some reviews commenting that hills are missing snd sadly they don’t seem to have read what they have downloaded. For a free app I highly recommend

### 1/5 — Incomplete

*2024-10-15, version 4.2.1*

So many missing off this

### 1/5 — Many missing hills

*2023-10-15, version 3.0*

I don’t know what ‘prominent’ in your opinion is.. to include Tal y Fan but not Drum or Foel Fras? Or why not Pen Yr Ole Wen? Quite ‘prominent to their surroundings’. Feels like some strange criteria for hills in North Wales. Won’t use as it doesn’t count so many great welsh mountains.
