Online Maths program, similar to something like Spellzone? Any recommendations?

[Scream2019]

Hello all, I would be grateful for any recommendations for online maths programs, please. Spellzone has been popular here so if there's anything out there similar or that does an initial test to set level, then that would be much better for us than starting at pre-set Y1, Y2, etc.

TIA

My daughter uses matific. She is 8, and it is mainly for primary school children. Many schools use this program for maths education. You have to pay a membership fee, but it isn't too much and you get feedback on student progress by email which is handy to know strengths/ weaknesses.

My daughter's school are obsessed with Mathletics. All their maths homework appears to be mathletics
