Verdict
The clearest difference is monetization model: Mello at free with in-app purchases against Lighter's subscription. Lighter's advantage is rating (5.0 vs 4.5) and ads (none vs shown). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mello sells 4 in-app purchases, starting at $14.99 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 4.5. That said, the two scores are not equally well evidenced: Lighter has 24 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on October 31, 2026 and November 3, 2026 respectively.
