21K App Review

The app has several glitches. Sometimes it stops working, stops tracking, restarts run, and doesn’t save a run. It can be very frustrating and I’ve given up on it. I’d say steer clear and save yourself some frustration.

Disappointing that it doesn’t count up in 5min increments as the 10km app does

Just finished the 10K training scheme and immediately downloaded the 21K app. Unfortunately, the 21K app is not as much developed as the 10K app. There are less instructions on the run, no encouragements during the run, the voice of the coach sounds robotic and there are bugs in the app (it does not register the information I provide on the date I performed the training). Overall, disappointing.

Fine app. Not a lot of details in the runs. Like speed and stuff, so If you want more details your better off with something else!

Would be perfect if it also had an Apple Watch companion app like the 5 and 10K apps do.

⭐️⭐️⭐️⭐️⭐️ ¡Perfecta para mi primer 21K! Hace 6 meses empecé a trotar, comenzando con la app de 5k, luego la de 10k y hoy corrí mi primer medio maratón gracias a esta app. Su planificación, consejos y herramientas de seguimiento son increíbles. Me ayudó a mantenerme motivado, a mejorar mi resistencia y a llegar preparado al gran día. Los entrenamientos están bien estructurados y son ideales tanto para principiantes como para corredores más avanzados. ¡Sin duda, la mejor inversión para alcanzar tus metas de running!

Great app, as I’ve already used the 5K and 10K apps and loved those! I’d be more than happy to pay for a lifetime subscription for the 21K app, but please provide Apple Watch support first!

Love the app but this version seems to lack the iwatch support that i realy like from the 10k runner app. Could this be added for the 21k runner version as well? Thanks a lot team! :)

Logré correr 10K con la App 10K runner empezando desde cero. Lo hice de manera progresiva y lo podido mantener en el tiempo. Confío que ahora podré correr los 21K con este excelente método.
