Oh as PP said, no need for apps, not sure what it would tell you. I am a biiiiiig fan of baby led weaning.
Have a google, there's a few good books on it and helpful supportive fb groups too. Basically give small finger food portions of whatever you're having and let them pick and play with it. They'll eventually eat it. Even without teeth they can get through anything cut appropriately.
Key things are: cut anything that is somewhat spherical into quarters: grapes, cherry tomatoes etc. Everything else can be in finger size pieces for them to hold. Our little one just eats whatever we eat and he never had anything mashed or blended. One of her first "meals" was spag bol. Messy but fun. She's a great eater.
It seems a bit strange (and new to people of previous generation who were used to blending or purring everything) but BLW is the older version of weaning again, and is back in vogue.
Means we don't need to meal prep etc, just serve a small, unsalted portion of whatever we're having. At 6m I just did one meal a day and slowly increased.
Today (at 12months) she's had weetabix and fruit, curry for lunch whilst out with us in a restaurant and having roast chicken now.
It's been so fun watching her explore and try things. I'd really recommend, though if you're nervous about gagging/choking I'd watch some YouTube videos to educate yourself but it's been fine for us.
But if you do want to purée there's loads of books out there
