Share the progress you're making on a goal/habit with one or more accountability partners.

Allow milestones to be broken down into smaller steps.

I have a few tasks where I need to track time. For example playing the piano. I I have a goal of 2 hours a week, and at the moment all I can do it count by minutes then do math to figure out 120 means 2 hours. This get more unweildy when I have a goal of 15-20 for something. It would be nice to be able to set a goal as a unit of Time, then add as units of time.

It is more dynamic, we could put the motivation for each goal than seeing the same popup. Hope this will work :)

Now I am achieving my target of twice per week, I want to increase this to 3 times per week without the past weeks all changing as they failed to achieve the new target, even though I did achieve the target of 2 times per week as it was at the time of logging it.

Add an option to start a timer for a Habit to make sure I did it long enough to count as done. For example, rather than marking "Clean House" as Done, I could set a countdown for 30 minutes to make sure I do it properly. Could apply to meditating, practicing an instrument, learning a language, focusing on deep work, etc.

For goals that have a start date & start value and an end date & end value, show a dotted projected line and an actual line.

For instance, if my current weight is 160, and my goal weight is 140, show a dotted line showing my expected weight any any time to meet my goal, and my progress to date with a solid line to highlight variances.

Productivity coaches such as Jason Selk and others recommend creating a daily success log in which a person records what went well during the day, what can be improved upon, and an action that can be taken toward improvement. You can kind of set something like that up, but only by using notes and kludging it a bit. Being able to create free form questions as a template and recording brief answers would be awesome. It would be an excellent addition to the app.

I track my sleep quality and my exercise, and I would love a feature that allows me to compare the results to find a correlation. Even just being able to visualize the graphs on top of each other would be cool.

I'd like to be able to configure reminders for a task to only be sent when I am (or am not) at a particular location (or locations). For example I'd like a reminder to stand up every 30 min, but only when I'm at my appartment.

Allow pictures to be attached to goals and milestones to help with motivation through visualization

Add some friendly competition with a leaderboard to challenge other people with the same goal.

Provide a way to import data from another app or from Excel. I've been using a tracker app for a few years and would like to switch without having to re-enter data into this app. If import is it possible allow some sort of mass update where user can select a time frame and enter in completion all at once. Or a calendar view where user can select multiple days and enter a habit for them all at once.

I'd really like to be able to add pictures to my log notes. Could this be a premium feature?

I would like to be able to set a group goal. And then the ability to sign people up for my goal (limited to invited guests) so that we all are working towards the same goal and can communicate and send encouragement and pictures etc. But the goal tracking is still at an individual level. Great for corporate, family or school goals.

Can you possibility add a search option. I have lots of trackers (and the tags help), but a search bar would be awesome.

Connecting the dots on a calendar to form a chain is very satisfying. A streak should be represented by a horizontal line running through the days the user has kept the streak. When the user breaks the streak the chain will break. This visual feature will motivate users to avoid ending their streak.
