Every so often someone asks what camera they should buy for a progress-photo project. The honest answer is almost always: the one already in your pocket. Resolution, lens quality, sensor size — none of it matters nearly as much as whether you're standing in the same spot, at the same distance, in the same light, every single time.
What actually ruins comparability
It's rarely image quality. It's a different room, a different time of day, a different angle, a phone held at arm's length one week and propped on a shelf the next. Those variables move the picture far more than a camera upgrade ever would — and they're also the variables you can actually control for free.
A tripod mark beats a better lens
If you want one upgrade that actually helps, it's not a camera — it's a fixed reference point. A piece of tape on the floor, a consistent shelf for the phone, a chair that doesn't move. That single five-minute setup does more for comparability than any hardware purchase.

SeeMyChange's whole design leans into this: instead of asking you to buy anything or learn photography, it shows a faint outline of your last photo on screen while you frame the next one, so "the same spot" stops being something you have to remember and becomes something the app just shows you.
