Hey there!
Great to see you diving back into micro tournaments on GGPoker and PokerStars. It's a vibrant scene, and the right tools can really boost your game.
For your specific needs, here's what I'd suggest:
Hand History Importing and Storage: Look for a tool that offers easy import of hand histories from multiple sites. This is pretty standard, but ensure it supports both GGPoker and PokerStars. A central storage feature is a must, and most tools let you organize your hands in subfolders or something similar for better management.
Graphs and Analysis: You're after something that gives you a clear view of your buy-ins, cash-outs, and a bit of AI-based analysis like equity-to-hand results. This is a bit more niche, but there are tools out there that offer sophisticated post-game analysis, including graphical representations of your performance.
No HUD or Player Stats: Given you're not looking for HUDs or opponent stats, you can skip the more complex (and often pricier) tools. Simpler, analysis-focused software will be your best bet.
Pricing: You prefer a one-time purchase over a subscription model. This narrows the field a bit, as many tools operate on a subscription basis, but there are definitely good options available for a one-off payment.
While I can't recommend a specific tool that ticks all these boxes (since it really depends on personal preference and playing style), I do have a suggestion. Check out this list from Edited. It's a comprehensive guide and should help you find something that aligns with your needs.
Good luck at the tables, and may the flops be ever in your favor!
