Verdict
The clearest difference is ratings volume: LectMate at 665 against 格式转换器's 2. 格式转换器's advantage is rating (5.0 vs 4.8) and iOS requirement (12.0 vs 15.0). On price, update cadence, ads 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. LectMate sells 8 in-app purchases, starting at $5.99 per 7 days and 格式转换器 sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
格式转换器 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: LectMate has 665 ratings behind it against 2, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 25, 2026 and June 7, 2026 respectively.
