Hi @Alexander1102, I have been using AirDna for a while now, was in my budget, but the data seemed off on many parameters, I didn't found it to be accurate, After some trial and error i settled on Airbtics which seems like a far better alternative than I have been using since January this year, you can use my referral code "Shivam15", you'll get 15% off using this code and ill also get 15% off on my next month's subscription, just mail this discount code to jae@airbtics,com and they'll send you a signup link. Hope it helps
