For those who want to just have fun instead of burning their brains when solving word puzzles... This app is meant to be used with word puzzle games whose goal is to guess 5-letter word in up to 6 attempts by indicating which letters in the guessed word are right, misplaced or wrong. Solvre will suggest the next word to guess in order to find the right word within the 6 attempts available. Once the game responds by changing background color of each letter of the last guessed word, simply tap on the letters in Solvre to change their background color to match the game's response. Here, grey color means the letter is not present in the word (or, if it has already been marked green on another position, that there is no more instance of it) yellow means the letter is present in the word but on a different position, and green means the letter is in the word exactly at the same position. Hard mode (available in settings) means that any subsequent guess must use the letters which have already been marked as green or yellow. Once you have marked each letter with green, yellow or grey, tap on Next Guess to get the next suggestion. Sometimes Solvre will offer multiple choices, then it's up to you to pick one and try it out. Have fun!

Verdict
The clearest difference is in-app purchases: Solvre at none against SpectraScan's 1. Solvre also leads on device support (3 vs 1) and iOS requirement (13.2 vs 18.6). On price and ads there is nothing between them.
