Verdict

The call

The clearest difference is review sentiment: LM at 88% against OBS 4K's 22%. OBS 4K's advantage is rating (4.7 vs 4.2) and update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. LM sells 1 in-app purchase, starting at $9.99 per month and OBS 4K sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

OBS 4K holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: OBS 4K has 25 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 88% of LM's written reviews are positive against 22% of OBS 4K's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

LM ships an update every 3 weeks, OBS 4K weekly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
