Verdict
The clearest difference is monetization model: RLM at free against LogTen Pilot Logbook's free with in-app purchases. RLM also leads on rating (5.0 vs 4.7). LogTen Pilot Logbook's advantage is ratings volume (10K vs 2) and chart position (#109 vs unranked). 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. LogTen Pilot Logbook sells 10 in-app purchases, starting at $9.99 per month and RLM sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
RLM holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: LogTen Pilot Logbook has 10K ratings behind it against 2, so its average is the more settled of the two.
LogTen Pilot Logbook ships an update fortnightly, RLM every 3 weeks. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
