Verdict

The call

The clearest difference is in-app purchases: SANS OnDemand at none against LetsDefend's 2. SANS OnDemand also leads on ads (none vs shown) and review sentiment (27% vs 9%). LetsDefend's advantage is rating (4.0 vs 3.6) and update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

LetsDefend holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: SANS OnDemand has 32 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 27% of SANS OnDemand's written reviews are positive against 9% of LetsDefend's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SANS OnDemand ships an update every 2 months, LetsDefend every 2 weeks. The most recent releases landed on October 10, 2026 and October 16, 2026 respectively.
