I use fatsecret on some days, but I'm very mindful not to let it interrupt my progress. I don't want to shoot for a target macro/micro goal because then I'm out of tune with what my body wants and needs. I did a leptin reset and used it mostly then, but now I feel like I can trust my hunger more. If you are gaining unexpectedly, it might be a good idea. I like fatsecret the best, the phone app is amazing.
