Cozy-themed Personal Diary Mobile App Design

I need a (quite simple) mobile app design, for a personal diary app. The design should be cozy and mostly girly (it's light and dark brown in my mind [monchromatic], but up to what i've tried to get done, I couldn't get the colors to work together). The app should have the following screens: - An onboarding screen, where the user is shown a welcome message and prompted to log in with Google to continue - A subscription screen, where the user subscribes either monthly or anually - A home screen, where the user can see their entries - A writing screen, where the user can write new entries. This'd have basic formatting options, which would include bold text, italic text, underlined text, and bullet/numbered lists. The buttons must only include - A profile/account screen, where the user can check their subscription, billing, delete their account, etc., plus editing some settings (which could be in a separate screen?). I'm a software developer and I've tried to get the app's design done, but had a not-so-good time trying to get things to look together. I've already got the icons for the app from MingCute Pro (I bought the license today). The design should be clean and intuitive. I'm looking for a pretty flat-looking app, if you could say it that way. Basically, no shadows nor elevated buttons/cards. A dark theme that is also dark brown would be really good too, definitely a plus. To get an idea of the theme I'm looking for, you can search for "iOS theme cute cozy" on Etzy (dot com), the results that pop up at the top (first rows) get quite close to what I'm looking for, but without the hand drawn style (im looking for a flatter, more minimalist look and feel). I'll be attaching some examples downloaded from there which get relatively close to what I'm looking for. I'd need the font(s) and colors to be chosen to fit the theme, and then design the app with those. I don't have any specific ones in mind, but something playful-ish like Nunito could work. The fonts must be free for commercial use, e.g. Google Fonts, fit the theme, and be easy to read since it's a book app where users can write for themselves (while having it's bit of style, i.e. not Roboto/Inter/Similar). I'll need the color palette's colors named (primary color, secondary, background, etc.) so that I can implement that programatically easily. Also, smooth subtle animations should be added for transitioning between screens, and maybe even icons too if they're in the animation pack from the icons. I don't have any animations/transitions in mind for the app, so you can surprise me with that. About navigation within the app, it'll ideally be a floating bar at the bottom of the home screen, which'll have 3 buttons: - My Book - Write - My Profile/Account I have specific icons in mind for each of the navigation button. Also, the write button should be different to the My Book and the My Account ones. I imagine it as a floating brown bar with a big border radius (the whole navigation bar) with the My Book and My Account at the sides, each of them with their icon on top which will be filled on select and their label under them, and in the center would be a circle button with no label, and just a pencil icon which would navigate to the writing screen. The subscriptions in the subscription screen could be a big header image with a title below (or no image) and cards displayed either side by side or vertically (there's a single price, which can be billed either monthly or anually with discount, so side-by-side cards could work but I feel that in smaller devices it won't resize well so a vertical list would be better for those cases. Maybe making it responsive?). You're do not need to make any illustrations/images for the app, like headers or banners. Upon full payment, all rights, including intellectual property rights, to the design will be transferred to the client (me). The freelancer waives any claims to ownership or future use of the design, except for the right to use images of the design in their portfolio and for self-promotion purposes. The freelancer is not permitted to replicate, reuse, or incorporate the design (or portions of it) into any other project or product, including but not limited to creating a similar app or product. I won't be working with Freelancers who spam automated messages without addressing this posting. I'm not looking for a rushed design, you can take your time with it as long as the outcome is well polished. A Figma file or similar will do the job perfectly well.
