Z5 allows you to synchronize your account with Strava (Garmin and Wahoo coming soon), where you can select a video and from this video it will try to obtain the metadata of different metrics, such as speed, heart rate among others, which can be added directly to the selected video and this can be shared or exported to your preferred application.

Verdict
The clearest difference is review sentiment: Z5 at 100% against DailyTSS's 33%. Z5 also leads on iOS requirement (12.1 vs 16.6). DailyTSS's advantage is rating (5.0 vs 4.0) and ratings volume (3 vs 1). 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. DailyTSS sells 2 in-app purchases, starting at $3.99 per month and Z5 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
DailyTSS holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews complicate that: 33% of DailyTSS's written reviews are positive against 100% of Z5's, so the app with the better star average is not the one people write more warmly about.
DailyTSS ships an update monthly, Z5 every 2 months. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
