First of all, good work devs and I wish you all the best with your project. I have a few suggestions, based on my experience with MCZ since the very beginning. This is meant as constructive criticism
Some points are probably also suggested by other earlier in the thread.
1. Get rid of the timer. Why limit both time and coins per day? It makes it unnecessary complicated, and in addition the timer does not work. Why not leave the app to generate/"mine" coins as long as it is running, just like before?
2. Make it interesting to take part in the project again. In other words, make it easy and make it possible to earn something. Due to problems with the app and the timer this is currently not the case. I would suggest a similar function as you had before. Make it possible to accumulate coins that can be generated. This can be set to expire after say 7 days, so its only the "leftover" coins the last days that contribute to the cap. This will make going on a long run/bike ride of say 5-6 hours worth it. If it is not possible to generate actual value, it won't be used. I'm not gonna bother with MCZ if I workout 5 hours and made 40 USD cents equivalent in MCZ (which is currently not even possible), and I doubt a lot of people will.
3. Sort out and communicate how value will be generated in the future. There was a cap before I think of 16M something. User expect a similar monetary reward, say in USD or BTC, for the same work. How will this work if you get a lot of users? How can you promote positive price / market cap gain?
4. Get the app working BEFORE you do any more promotion or referral campaign. As is it is now, I doubt anyone would stick with it, unfortunately.
5. Make the algorithm that decides rate of generated coins depend on both phone movement and rough distance travelled (using location, from cell towers should be enough to keep battery use low).
6. Find a good strategy to avoid people gaming the system (tumble drying a farm of phones, emulators etc).
7. Don't associate yourself with other cryptos. It's clearly not the same and functions is a widely different manner, and you will receive a lot of criticism for it.
