Comments on SpotLog for Android

★★★★★ Steve Nixon · Jan 13, 2024
In 2016 (yes, 8 years ago), I was looking for an app to log all my train numbers. Then, I came across this on and will admit for 8 years I've never looked back. I have highly recommended this app to newer people on my travels across the Northwest of England who have started the hobby. (Mark and the team, please keep up the good work. You all are a massive credit to the community of the train family)
★★★★☆ A Google User · Mar 20, 2015
Very good app. I really like this app. It has occasionally annoyed me by crashing but not often. Works well on my Sony Xperia SP. There are a few things I'd like to see in future updates: 1. Being able to 'tick' when you have had a loco/unit as haulage to view separately with something like a blue tick. 2. It'd be nice to be able to produce a report on what locos are unseen from a certain class. i.e. Class 377 requires 377603, 377612 etc. 3. Would like to see datasets for the UK Trams, London Underground, Austrian Urban, Austrian Trams. 4. Maybe a different way of deleting a loco/unit (I deleted a few by accident but restored them using datasets or and undelete function). 5. A better link to website/help function. Maybe have the help file as a PDF or ebook file on the site to download and save to your phone when out of a 4G area. Would I recommend this? I sure would. I have given 4 stars but with the ideas above it would be a flat out 5*. Thanks for a great little program

Unfortunately it always crashes on launch: Get sets: Exception System. NullReferenceException: Object reference not set to an instance of an object at SX2. Services. WebAPIService. GetSets 🤷‍♂️
★★☆☆☆ John M · Aug 19, 2026
The app works OK, but it does have some bugs and has seen better days. We only use it for recording numbers now, which we to export to excel. This year, we noticed a lot of new locos, units and trams are missing across multiple countries. The data updates are less regular, so the loco info is more out-of-date now. Overall, a nice concept for an app, but needs better data input and maintenance to keep it relevant for spotters.
