Would be better with some progress trackers and interactive notes ### 1/5 — Lost my progress at day 70 *2023-10-12* App lost all my data at day 70 ! Don’t buy this app ! ### 3/5 — Separate the two workouts *2023-09-16, version 4.0* Is it possible please to edit the title of the fixed tasks? Also I would love if the two workouts were separate tasks so then when I finish one I can actually tick something off- please separate them. Every app has them together and it’s frustrating ### 1/5 — Terrible *2023-09-13* I wish I would have been able to view the app prior to purchasing because it’s not useful to me at all. If they would add a grid so that you could view your progress for the entire 75 days it would be so much better. ### 1/5 — DONT BUY *2023-07-10* Absolute waste of money. ### 2/5 — Lacking *2023-03-20* While the idea of this app is nice, I downloaded it a day prior to starting my challenge and it won’t update to the next day, it stays stuck on the day I downloaded the app. None of my options save either- when I mark off a task, it still says I didn’t do it. ### 1/5 — Won’t refresh the days. *2023-01-12* The app is stuck on the previous day and won’t go to the right day until the evening, so you’re operating a day behind. ### 1/5 — Unintuitive *2022-11-14, version 3.6* The free version is buggy and the flow doesn’t make any sense. Do not recommend. ### 1/5 — Would not recommend *2022-11-12* You could do everything this offers on your own 🗣for free ## Frequently asked questions about 75 Day Challenge ### What is the 75 Day Challenge app?
