Takes the thought out of planning *2026-08-21* Great app. Allows for music to still play. Good run walk run method. **Developer response:** Thank you for your 5-star review!! Don't forget to recommend the app to all your family and friends. ### 4/5 — ALD *2026-08-10, version 7.3.31* 4 stars ### 5/5 — 10K trainer *2026-08-03, version 7.3.31* Easy way to build up to running! ### 5/5 — Amazing *2026-07-25, version 7.3.31* It feels like you have 24/7 Personal trainer ### 5/5 — The best way *2026-07-24, version 7.3.31* The best way ### 1/5 — Requires payment *2026-07-17, version 7.3.31* Boooo. I used C25K to train for my first 5K and loved it. I just downloaded C210K and realized it requires payment to use more than the first 3 runs. Deleting it now. ### 5/5 — Awesome! *2026-07-14, version 7.3.31* Great for beginners! ### 1/5 — Miserable Customer Service *2026-07-12, version 7.3.31* I’ve been trying to get an issue fixed for over a month, but customer service keeps giving me the runaround. All I want to be able to do is correct my distances when I run on a treadmill, but the app only accepts commas for decimals, and a United States keyboard only offers digits and the decimal point. The reps don’t even bother reading my actual complaint, and instead seem to be trying to follow a script that was never intended to be used for my issue. I’m starting to think the rep who emails me is actually a chatbot, and not a human being. ### 5/5 — Free version is great *2026-07-03, version 7.3.31* The free version is great for those on a budget. It does what it says in the tin and keeps you motivated ### 5/5 — Awesome *2026-07-02, version 7.3.31* But with Jasem ## Frequently asked questions about 10K Trainer by C25K® ### What does the 10K Trainer app do?
