Look for a good day to start something important ! In addition, you can take note of anything happening on that day so that you can later compare with the accuracy of the prediction. You will be surprised to see what happens if you go back to those really bad days and check in retrospective and keep adding notes. You can also generate lottery numbers on the fly.

Verdict
The clearest difference is ads: AstroLuck. at none against Tio! 4D's shown. Tio! 4D's advantage is update cadence (every 2 months vs every 18 months) and iOS requirement (11.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.
