# LotDate vs ScentMax

LotDate and ScentMax both sit at 4.8 stars, but that hides the real split: 91% of ScentMax's written reviews are positive against 47% of LotDate's. ScentMax also leads on iOS requirement (15.1 vs 18.0). LotDate's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 4 days vs every 3 weeks).

Both are free to download. LotDate sells 3 in-app purchases, starting at $2.99 per month and ScentMax sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
