Are you sure you're building something that fundamentally is valuable enough to an audience that is willing to pay money for it in exchange?
Have you validated that that's true?
I didn't validate the value before building, and justified it because I wanted to use it for myself. So I built a tool for myself and now let others use it.
"Detects project name from repo- so your work is never XXX"
"See logged time per project or branch- so you can see XXX"
Then tell me why I want the investment: "If you value your time at $50/hr then for the price of 11 minutes you can save yourself hours of lost time each month" or whatever the selling point is.
This will have three effects: It will make your pitch more compelling; it will force you to focus on selling the features that matter; and it will allow you to see the features you should add in order to have a more compelling sales pitch.
If you are looking for something to duckduckgo, this is old news, and it comes down to "selling features vs selling benefits" in marketing.
If that rate is under 1% for active free users moving to paying users then it's definitely a value problem. (Active, not just made an account and a capture). If this is the case then you probably need to working on adding additional features that are paid only and valuable.
If the conversion rate is alright but the total number of users is just too low that your paid users is too low, then it's not value problem, but rather a marketing problem. Two options in this case: your product is useful but the people who would use it don't know it exists, or your product is not fitting a market need. I'm pretty sure it's the first case, but validating that is difficult. As it's useful to you and does seem useful, the best step is to just try to get more people aware of the product. I'd recommend writing (or paying someone to write) blog posts detailing how your product is used. Tutorials on starting up a freelance business using your product to keep track of time for clients, or blog posts on time manegement using your product as a center piece would be good. Post those blogs up to twitter, HN, reddit, etc.
