Verdict
The clearest difference is rating: Walker's Link at 4.5 against SIG BDX's 3.4. Walker's Link also leads on ratings volume (3K vs 68) and iOS requirement (14.0 vs 16.0). SIG BDX's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support 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. Neither carries in-app purchases, so what you see is what you pay.
Walker's Link holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: Walker's Link has 3K ratings behind it against 68, so its average is the more settled of the two. Written reviews complicate that: 33% of SIG BDX's written reviews are positive against 14% of Walker's Link's, so the app with the better star average is not the one people write more warmly about.
SIG BDX ships an update every 3 weeks, Walker's Link every 2 months. Both last shipped on October 22, 2026.
