Verdict

The call

The clearest difference is rating: Topo Maps+ at 4.7 against SIKU's 4.0. Topo Maps+ also leads on ratings volume (9.4K vs 4) and chart position (#91 vs unranked). SIKU's advantage is in-app purchases (none vs 10) and review sentiment (80% vs 62%). On price, update cadence, ads and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Topo Maps+ holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Topo Maps+ has 9.4K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 62% of Topo Maps+'s written reviews are positive against 80% of SIKU's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 12, 2026 and November 6, 2026 respectively.
