Yes indeed @elianaicgomes has said the biggest truth its really very difficult to choose the best hive dapp.
In my view @actifit app is the best app so far cause because of these features:

• It counts your every physical activity.
• Does not asks the presence of internet to count your activities.
• At night it only takes 5 to 10 mins at max to use internet and submit your post.
• Light weight than any other DAPP.
• Runs in background passively without draining your battery and without consuming mobile resources.
• Introduced DeFinance as well within the app.
• Can submit your post both to Steemit and Hive.
• Gives you the option to make same passwords for both above mentioned blockchains.
• Bringing easy to use token bridging from hive to Bsc(Binance chain)
• You can buy physical gadgets from the app.

Most important feature makes you Healthy by encouraging to take part in Physical Activities Contest.

They say Health is your Wealth.
