Do you have an Android Phone?
Do you need something to make your spotting life easier?
Fed up with your books getting messy?
All kidding aside folks, I dicsovered this via various sources and I have to say I am exceptionally impressed. Go to Google play store and search for spot log.
There are some European datasets but there is a very well maintained UK dataset. Also there is a preserved dataset with the steam and modern traction listed in it. The people behind it are working on a UK:70 one with all previously locos from 1970 to 2000 on the database so old sightings can be logged too 🙂
I used it previously to put in a lot of old 40s, 45s, 47s, 37 etc. and the UK:70 has them all listed from trips to Crewe Works Open days, Tyseley Open Days etc,. I am working on updating the Austrian traction list (anyone that can provide info let me know).
Honestly I like the notepad function when I am at work, there is a log you can make reports from, and the datasets can be viewed as a book making it easy to know if you have seen a loco (or Unit) before.
Honestly for a FREE app it is amazing and if it cost £5 then it would still be worth it.
There is a forum to use if (Click for forum) you can log an issue on and also if you want to help then that’s the place. Good friendly bunch too 🙂
