Instructions about when to turn round at the halfway point particularly so. I’ve used the 5k and the 10k and now on to 21k. Love them. -- Reetlondon, 2024-05-20 ### ***** "Well on my way!!" LOVE this app!! It is keeping me in check with my prep for half marathon and it’s taking me at a pace that is challenging but comfortable at the same time. When I first started using the app I had to have pauses because my endurance was not the greatest but now I can run at a comfortable pace non stop for 45mins and it’s only been just under 2wks!! -- DreaDans, 2024-04-21 ### **--- "Forgets my progress" I like the app for its training plan and badges, but it keeps forgetting my progress and customer support doesn’t get back to me. -- EllieS1307, 2023-09-05 ### ***** "I always use the Fitness 24 Apps for my training" Love the fitness 24 apps for building up my stamina and pace. Used this one for great north run 2021 and after having another baby glad to be back at it again! -- BadgerNanan, 2023-07-19 ### **--- "Easy to follow but glitchy" After using the couch to 5k version of this app I wanted to follow a training plan to comfortably run a HM. The app could do with more advice for strength training as there is none, and more variation including hills, fartlek, pace changes. I am only four weeks in and finding that the plan is a bit boring and having to find my own ways of mixing it up. Each time I open the app I seem to lose anything up to 3-4 days progress and have to declare once more ‘I did it’. They say if you buy cheap you buy twice and I now feel I should have opted for one of the more expensive apps. -- Thatblokedan, 2023-06-17 ### ****- "Love this app but" Love this app well planned runs but find it’s started to not store my run data and twice it would not open. Not big issues just frustrating as having to keep a manual record of where I am at but overall good app and good value -- Dodocat67, 2023-06-16 ### *---- "Appalling customer service" I have sent 3 messages to the support team and several emails to the 21K contact address regarding the loss of data . The issue is that after a run it will record distance and calories burned, but the next day this information has gone . This is very frustrating as I need to now exactly how far I have run in prep for the half marathon. Hence, assuring I am on track with regards to mileage . The fact that this app isn’t free is disappointing. Avoid at all cost as I have received a much better service from free apps . Clearly a no brained for anyone considering whether they should subscribe ! -- soggysocks!, 2023-04-28 ### ***-- "Disappointing" I bought this app after using their excellent 10k app. Unfortunately, this one is nowhere near as polished. No Apple Watch app, the voice prompts are very limited, and the app regularly loses the last couple of runs worth of progress. A real shame. -- appdav, 2023-04-24 ### *---- "So disappointed" I was really enjoying this app but it has stopped logging my runs since week 4. I am still able to use it and do the runs but it’s very disappointing that my total progress is not being recorded and the runs I am completing have disappeared by the next time I log in. I have contacted the app multiple times to report this and have had zero response. Considering I paid this time I am gutted. -- kirstd74, 2023-03-23 ### *---- "Poor version of the 5k amd 10K app" Really disappointed. Loved the 5k and 10K. Jace emailed them with problem in not connecting to apple watch. No reply 3 days later. Really uninspiring it’s a cheap version of the other two. Don’t bother with this version get another. After the 5k amd 10K app expected the same or more and got a lot less! -- Shortstuffblonde, 2023-01-20 ### *---- "Apple Watch" Used 10k which worked with Apple Watch and this doesn’t! Don’t want to carry phone in long runs thanks. -- Degsy34, 2023-01-19 ### **--- "Sorry to say it…" I really loved both the 5 and 10k apps. They totally worked and before that point I couldn’t even run for a bus. They are GOLD! So it was an instant 1-Click purchase for the 21k version. I was so disappointed!!! It’s just not the same. It’s like they couldn’t be bothered! The ladies voice sounds a bit more muffled than previous versions and she just barely speaks! She used to say “you’ve got this!” And other things. But now she just tells you when you are halfway or when to cool down. I just don’t feel this was worth the money when there are other plans out there. It’s a real shame. I won’t be buying the marathon version :( -- jaypeg17, 2022-12-29 ### *---- "Lost data" This app is not saving my runs or keeping track. It’s just wiped a weeks worth of data. -- veggie mark, 2022-11-27 ### *---- "Mint a good app and no support" Paid for the app so I could see all the functionality and I established it wasn’t for me. I’ll continue with Strava and my own training. I mailed support to ask for a refund as I have not used to run and I have not had a response. -- the-scot, 2022-10-21 ### *---- "Not great" There are no motivational prompts so I might as well just run timing it with a watch. -- Wonderous Claire, 2022-10-18 ### *---- "Don’t waste your money" Have emailed customer service numerous times as the 22K doesn’t sync to App, zero response. Contacted apple and they were helpful but ultimately not a fault through them. Into week 4 now and all running data has been lost, shame as I enjoyed 0-5k and 10K. -- Chris197256, 2022-10-06 ### *---- "Much worse than 5k and 10k versions" After using 10k app, I subscribed to 21k assuming that the app would have the same level of integrations and functions. Oh how wrong I was…The minimum prompts are of terrible sound quality, listening Spotify will override the prompts so you can either listen to the music or hear the prompts, the app is not available on Apply watch, the list goes on. Im so disappointed and would like to get an refund. -- GeeJamJM, 2022-09-22 ### ***** "Great App" Simple to use and follow. -- YazzyG, 2022-08-30 ### ***** "Frustrated" Completed! Thank you but how do I reset the app, as I would like to train for another. All runs showing as completed. I have also emailed the developer and not heard back. -- jez71, 2022-07-31 ### *---- "@£&" Apparently this app has been updated (3 years ago) to view on Apple Watch. I don’t se the app on my Apple Watch? -- Westie78, 2022-07-26 [View all Half Marathon Trainer reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Half Marathon Trainer In-App Purchases | Item | Price | |------|-------| | Premium Subscription | £7.49 | | Lifetime Premium | £14.99 | ## Half Marathon Trainer Discovered Keywords -
