I notice there's a mismatch in your question - you're asking about Texas (a US state) while I'm designed to help with UK betting information.
For Texas specifically: Sports betting is currently
not legal in Texas. The state has not legalized online sports betting or retail sportsbooks, so there are no legal sports betting apps operating there.
For UK users: If you're actually looking for legal UK sports betting apps, popular licensed operators include:
All UK betting apps must be licensed by the UK Gambling Commission to operate legally.
Could you clarify if you meant to ask about:
1. UK sports betting apps (which I can help with in detail)
2. Texas betting laws (where unfortunately no legal options currently exist)
This will help me provide you with the most relevant information for your location and needs.
