Verdict

The call

The clearest difference is review sentiment: Slack at 55% against HighLevel's 25%. Slack also leads on ratings volume (52K vs 3.7K) and chart position (#19 vs unranked). HighLevel's advantage is rating (4.5 vs 4.1) and monetization model (free vs freemium). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

HighLevel holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Slack has 52K ratings behind it against 3.7K, so its average is the more settled of the two. Written reviews complicate that: 55% of Slack's written reviews are positive against 25% of HighLevel's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Slack ships an update weekly, HighLevel every 10 days. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
