Too ugly for dating apps? M25

I've been on dating apps since I was 25 and I've never had a date despite constantly updating my profile with new pictures and updating the bio so it's relevant to my current situation.
Some quick info on me I'd say I was a 3 or 4 out of 10 in looks. I've got a fat face despite having a low body fat. I work out regularly and am toned. I am an aerospace engineer and I earn well above the national avg for my age. I'm 5'7. I've got an upturned nose so I look a bit pig like tbh. I like travelling and seeing new stuff.
I was very fat in school and was bullied relentlessly so I had literally no friends from the age of 11 to 19 so I never really learned how to talk to people my own age, this obviously didnt help with asking women out. I spent most of my time with my mum so my hobbies are like hers.
After i lost all the weight and got my life together I've realised i might have a shot with women now but I keep getting rejected for silly things.
Any advice on how to be nore successful on these apps?

Have you been receiving any messages on the apps, and if so, at what point have you been asking people whether they’d like to meet up?

You won’t be successful on dating apps unless your reasonably attractive.
Dating apps are a cancer to long term dating selection because they force women to select men (even for long term) based on short term aesthetic considerations which means that according to academic studies, around 80% of men are rejected.
You would be highly advised to meet somebody via real life in a social context (walking club, social events ect..).

Any advice on asking someone out in person?

Don’t overthink it, converse about something and then say ‘your pretty, meet me for x tomorrow’.

OK do I ask for their phone number?

I’d just get the number afterwards personally otherwise you’re just adding an extra step.

The convo usually ends before I get the chance

If you are getting a few messages then your pics aren't a dealbreaker.
You will always find that most conversations die out before getting anywhere. It's not reflective of you, just the nature of online dating. Keep things light and friendly, demonstrate that you have read the other person's profile and if you are having fun chatting ask them if they would like to meet up for a coffee. That's about all there is to it.

if you're making a lot of money perhaps invest that into something to make yourself look petter (plastic surgery) Don't be ashamed, a lot of men do it.

I was told my texting felt like an interrogation but I was just asking questions.

You have a decent salary, by the sounds of things. How come you are still living with your mum in your mid 20s? This is likely to put some women off.
