But it does give some important clues on training and ability. It is an excellent tool, even though at times imperfect in its results. ### 5/5 — Top *2022-02-13* Top ### 5/5 — Útil *2022-02-12* Excelente aplicativo pra quem treina sozinho e possui um conhecimento básico de treinamento esportivo! ### 5/5 — 参考になります *2021-04-04* 日々のランニングやジョグの参考になります。とても良いです ### 5/5 — Russian language *2020-09-20* When will the Russian language appear? Very necessary! ### 5/5 — App *2020-09-15* 👍👍👍 ### 5/5 — Great app for aspiring athletes 🙏🙌 *2020-09-15, version 2.3* If you are serious in running and want to improve, this is the app for you along with VDOT02 app😀 ### 3/5 — Used to be great *2020-08-29* This app used to be my go-to for running based calculations. But the most recent update (Aug 2020) limits you to 3 calculations per day unless you upgrade to the not-so-cheap premium version. Sorry, but there are other free apps out there to do simple arithmetic. Deleted. **Developer response:** Johnny, we just updated the application in version 2.2 so you can do unlimited calculations without having to use premium. Let us know what you think. ### 5/5 — 素晴らしいアプリです *2019-10-26* 大学で5人の自己ベストとVO2maxの値、および閾値強度を比較させていただいきました。相当と妥当性が高いアプリだと思います。 環境がない高校生の選手や、市民ランナーの方は是非活用していただきたいアプリです。 ### 5/5 — Does its job and does it well, but one suggestion... *2019-09-08* Great app and seamless to use. My only suggestion and wishlist for this app would be to add 6k and 8k to the list of common distances (as I believe the 1600 and 1500 were added not that long ago?) as to make it a little easier instead of having to custom distance those every time for the collegiate users out there and these being two standard cross country distances. Otherwise thank you for all the hard work you’ve put into making this app what it is! **Developer response:** We've added 6k & 8k distances! ### 4/5 — Great but it does bin data all the time *2019-05-25, version 1.5* I wish it would remember previous data. It’s a pain to have to re enter data every time you open the app. ### 5/5 — Cannot see definitions *2019-03-15* This app doesn’t allow you to see their definitions of their workouts, making the times it calculates almost useless. If this would be fixed I would rate it a 5! They got back to me and fixed the problem. 5/5 **Developer response:** James, This was due to an issue with the latest iPhone. We went in and fixed this issue. Can you update to the latest version and let us know if you have any problems? If so- you're welcome to email info@vdoto2.com if you have any problems and we will get back to you ASAP. ## Most critical reviews (10 lowest-rated) ### 1/5 — What happened?! *2022-02-24* App was apparently just updated and now won’t open. **Developer response:** We updated the app some time ago and are unaware of any issues with opening it up. Can you send us a message to info@vdoto2.com so we can help you further? ### 1/5 — わかりません *2020-10-17* 使い方派わかりません ### 1/5 — New charges! *2020-08-29, version 2.1* Used to be free now you have to ‘go premium’ to get any more than 3 daily calculations! This used to be a convenient app but not any more... delete! ### 1/5 — Almost there *2020-08-28* If only it would remember the data and not have you enter it every time you open the app.... Update: fixed one thing, broke a few more. Plus added "pro" for smth that was there before.... Too bad. Had such potential, but it's time to delete it. Adios! **Developer response:** Hi Musashi, We updated the application and added your request. Let us know what you think! VDOT O2 ### 1/5 — Doesn't work with custom distances *2015-09-25, version 1.0.2* Useless unless you have race results. Won't do calculation if you input custom distances. So rather pointless for tracking evolution of your fitness from week to week - I don't run races that much but I do track my distances that I run. ### 2/5 — Crashes *2024-12-28* I try to upgrade the app to premium and it crashes and closes abruptly. ### 2/5 — Whats the difference between this one *2022-11-17* Hi Want to ask should this app to be paired with the vo2 app? I don’t get it, what’s the difference between the 2? Don’t tell me I’ll have to purchase both?? **Developer response:** Hi Abby, You might be thinking of the V.O2 training app as that is separate. You don't need to pay for this app to perform calculations. Feel free to send us a message at info@vdoto2.com and we can explain in more detail. ### 2/5 — Completely unusable without quick manual vdot entrance. *2019-05-23* Subj ### 2/5 — Has some bugs *2018-04-11* You can’t see anything beyond 200 and 400m training results (app won’t let you scroll through the table) and when you click on links for definitions of Threshold, Marathon, etc., it takes you to a page, gives you the first part of each definition and ends in “...” with no ability to see the full definition. **Developer response:** We made an entirely new update. Let us know what you think! ### 2/5 — Custom distance fail *2015-05-05, version 1.0.2* It could be as great as web version, but I can use the custom distance option because always crash down. I can't read definitions. ## Most praised reviews (10 highest-rated) ### 5/5 — Referência para treinos *2026-08-17* Excelente aplicativo, que nos mostra de forma prática as métricas que devemos respeitar e cumprir para alcançarmos nossos objetivos de corrida. ### 5/5 — Бесплатно *2026-04-11* Отличная программуля. Откройте на месяц бесплатно разок. ### 5/5 — Great tool *2025-06-05* Very helpful for setting paces in training. Of course it requires you have a few good data points (race times) as a starting point. ### 5/5 — 丹尼尔斯VDOT *2025-02-20* 本人一直使用和研究丹尼尔斯理论，想实践化、本土化，感谢丹尼尔斯教练 ### 5/5 — いいかも *2025-01-14* ジョギングやランはするけど 今のタイムから練習の強度の参考にしたり 夏場に遅くなる時にどの程度なら同じ負荷なのかとか数値で出るのはありがたい！ ランの黙秘作りには良いアプリかなと ### 5/5 — 很棒的跑步工具 *2024-08-12* 非常好，对我帮助很大，希望还能增加更多功能 ### 5/5 — The best *2024-08-09* Simplicity of use is it’s beauty ### 5/5 — V Dot *2024-04-18* Extremely helpful! ### 5/5 — タイムの予想が出来てありがたい！ *2024-01-23* ５キロ走、１０キロ走、ハーフマラソンの結果から、フルマラソンの予想タイムがわかるので、トレーニングの目安になる。ありがたい！ ### 5/5 — V good but make some changes!! *2023-05-31, version 2.10* Great app but please edit the time field to be more inclusive of ultras (up to 24hrs?)! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
