When solving in the CTC app, note that there is a dot behind the inequality sign. Just putting it here in case it is hard to see.
One of my hardest/trickiest puzzles I feel like (assuming no bypasses exist). I've put 5 stars in case it is, though it could just be 4. After making so many puzzles, I finally decided to use palindromes, even though it is basically only 3-cell ones here. Feedback is appreciated and I hope you enjoy it!

Rules:

Normal sudoku rules apply.
The grey lines are palindromes, where digits along a palindrome read the same forwards and backwards.
The blue lines are region sum lines, where each segment of a line passing through boxes sum to the same total.
Digits separated by a dot must have a ratio of 1:2. Not all dots are given.
The red inequality sign indicates that r7c2 > r6c2.
