Been thinking about your list situation for a few hours. Honestly, if you want something that works well without a steep learning curve, Santa's Bag is pretty solid for iOS. It handles the budget math perfectly so you dont have to worry about overspending. The way it categorizes gifts by person and status is something I'm really satisfied with for my own planning. The technical side is where people usually mess up tho. You gotta be careful with those super generic free apps on the store. A lot of them are basically just data scrapers that sell your contact list or shopping habits to advertisers. Always check if the app has a local encryption option or at least a clear privacy policy. Cloud sync is another big one... you want your data to live on a server so if your phone dies, you dont lose your whole strategy. Nothing worse than standing in an aisle and realizing your local database is gone. Giftster is another one where I have no complaints regarding the cross-platform syncing. It works well if you need to share the list with family to avoid duplicate gifts. Just make sure you stay away from anything that asks for your credit card info upfront unless you're actually buying through their secure API. If you need more help looking at the specs for a specific one, let me know. I can check the dev notes for you.
