# Protocol Her vs Lighter

The clearest difference is monetization model: Protocol Her at freemium against Lighter's subscription. Lighter's advantage is ads (none vs shown) and rating (5.0 vs 4.8). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. Protocol Her sells 3 in-app purchases, starting at $9.99 per month and Lighter sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Lighter holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 10 and 24 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

Protocol Her ships an update weekly, Lighter every 4 days. The most recent releases landed on November 5, 2026 and November 10, 2026 respectively.
