Verdict
The clearest difference is rating: Coordinates at 4.6 against Maplet's 3.8. Coordinates also leads on ratings volume (6.8K vs 4) and review sentiment (64% vs 50%). Maplet's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model 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. Coordinates sells 6 in-app purchases, starting at $1.99 per month and Maplet sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Coordinates holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: Coordinates has 6.8K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 64% of Coordinates's written reviews are positive against 50% of Maplet's.
Coordinates ships an update monthly, Maplet fortnightly. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
