Useless *2025-10-01* There‘s no voice, so the app seems to no longer work with iOS 26 or even lower. ### 5/5 — アップルウォッチに対応して *2023-09-26* 有料で良いのでアップルウォッチで使いたいです。 ### 1/5 — Doesn’t work *2023-08-04* I see that the app haven’t been updated in 8 years (it’s currently 2023). That should have been my first clue. The app doesn’t work, I tried multiple times. Every time when I went to take my phone out of my pocket after doing a start, it was on some random app download screen lol. Too bad, would have been great if it worked. ### 4/5 — とっても重宝してます。 *2023-04-23* 1人の練習でもSDができる優れもの。リアクションも見れるので素晴らしい。 【要望】 Marksの前に空白の時間を作ってくれるとありがたいです。 Marks-setの時間を長くすればいいのですが、1人だとその前の時間もあると最高です。 ### 5/5 — Fantastic *2021-08-29* Very simple app for starting races in training runs ### 4/5 — An outstanding tool for block starts! *2020-07-09* Works well to monitor start technique and assess/compare each block release. ### 4/5 — Sprint start *2020-07-09* Would be better if times were recorded. If you are not quick enough to get back to the blocks you miss your times. App has been a favourite of my junior sprinters ### 5/5 — It works *2019-04-09* Pretty neat ### 1/5 — No updates. Bugs. *2018-12-12* Purchased the updated version to use the camera interface. The app won’t even ask me to allow the use of the camera. So I went ahead into the privacy -> camera -> and start meter isn’t even listed in the app section. There is a bug here he hasn’t fixed in years. Hopefully the developer will get back to me or I will need my $$ back. ### 2/5 — Audio *2018-07-12* Wie spricht die App zu mir? Gibt keinen Ton! ## Frequently asked questions about SprintStart ### How does SprintStart work? SprintStart provides audio commands and a shot sound to simulate a race start.
